Open session on geoscience instrumentation and methods
The Open Session on Geosciences Instrumentation is the European forum with an open call for professional conference papers in the field of Geosciences Instrumentation, Methods, Software and Data Systems. The session aims to inform the scientific and engineering geosciences communities about new and/or improved instrumentation and methods, and their related new or existing applications. The session also deals with new ways of utilizing observational data by novel approaches and the required data infrastructure design and organization.
The session is open to all branches of geosciences measurement techniques, including, but not limited to, optical, electromagnetic, seismic, acoustic and gravity. The session is intended as an open forum and discussion between representatives of different fields within geosciences is strongly encouraged. Past experience has shown that such mutual exchange and cross fertilization between fields have been very successful and can open up for a break-through in frontier problems of modern geosciences.
The session is also open for applications related to environmental monitoring and security providing, like archeological surveys, rubbish deposits studies, unexploded ordnance and/or mines detection, water dam inspection, seismic hazards monitoring etc.

Autonomous Uncrewed Aircraft Systems (UAV): Geoscience Research Platforms for the 21st century
Autonomous and unmanned systems are changing the way that we collect and process geoscience data. Their capabilities and potential applications will only continue to grow. Automated systems are now used for routine data collection in high risk environments, emergency response activities, and precision agriculture for species composition monitoring and evaluating vegetation health. The aim of this session is to bring together geoscience researchers to present on the newest systems, payloads, and research goals. We invite contributions from those integrating these autonomous systems into their scientific research, system and sensor development teams, as well as those operators working on the integration of unmanned aircraft systems into manned airspace. The session brings together experts in all aspects of autonomous and unmanned system mission planning, regulations, operations, data collection, processing, and analysis to foster interdisciplinary research and knowledge-transfer across the sciences.

Beyond the unconstrained: Driving and assisting cryospheric models with observations
This interdisciplinary session brings together modellers and observationalists to present results and exchange knowledge and experience in the use of inverse methods, geostatistics and data assimilation - including machine learning - in cryospheric science.
In numerous research fields it is now possible not only to deduce static features of a physical system but also to retrieve information on transient processes between different states or even regime shifts. In the cryospheric sciences a large potential for future developments lies at the intersection of observations and models with the aim to yield prognostic capabilities in space and time. Compared to other geoscientific disciplines like meteorology or oceanography, where techniques such as data assimilation have been well established for decades, in cryospheric sciences only the foundation has been laid for the use of these techniques, one reason often being the sparsity of observations.
We invite contributions from a wide range of methodologies - from satellite observations to deep-looking geophysical methods and advancements in numerical techniques, and from topics including permafrost, sea ice and snow to glaciers and ice sheets, covering static system characterisations as well as transient processes.

New data and methods to explore the interplay between natural hazards and social vulnerability
Increasing effects of climate change, urbanization, and increased interconnectedness between ecological, physical, human, and technological systems pose major challenges to disaster risk management in a globalised world. Economic losses from natural hazards and climate change are still increasing, and the recent series of catastrophic events across the world together with the COVID-19 crisis has manifested the urgent need to shift from single-hazard-based approaches to new and innovative ways of assessing and managing risk based on a multi-hazard and systemic risk lens. This calls for novel scientific approaches and new types of data collections to integrate the study of multiple natural processes and human influences triggering hazards, including studies of ecological, physical, socioeconomic, political, and technical factors that shape exposure and vulnerability of humans, sectors and systems across borders and scales.
Tackling the above challenges, this session aims to gather the latest research, empirical studies, and observation data that are useful for understanding and assessing the interplay between multiple natural hazards and social vulnerability to: (i) identify persistent gaps, (ii) propose potential ways forward, and (iii) inform resilience building strategies in the context of global change.

Soil pollution versus natural background as a source of ecological and geochemical risk and imbalance of elements in biota and spread of endemic diseases
The soil is a key system of the biosphere that supports the existence and development of human civilization. However, the growing anthropic activities are accompanied by an expansion of soil pollution. From a geochemical point of view, anthropic activities lead to the emergence of a new state of the biosphere - the noosphere, when anthropogenic chemical elements and their compounds are added to natural soil. This determines the current spatial heterogeneity of the chemical composition of the soil and vegetation cover. Such an alteration to soil composition/properties can cause negative biological impacts on both native and introduced species in local biocenosis, as well as the emergence of endemic diseases among plants animals, and humans. Human diseases can be aggravated by the fact that Homo sapiens evolving as a species under certain environmental/geochemical conditions inherited a corresponding need for certain dietary elements to maintain homeostatic regulation. As a result, people, like other organisms, need to ingest elements in the correct amounts, otherwise, they suffer from a deficiency or excess of these elements. A negative reaction may occur when the species’ natural metabolism fails to compensate for this imbalance in the life cycle. Therefore, complex studies on the identification, spatial distribution, migration, and concentration of the contaminants in soils, plants, and surface and groundwater in urban, mining, agricultural/forest, and natural areas, as well as its biological effects, is an essential issue and important task for 1)identification of zones of different natural and man-made ecological risks; 2)understanding contaminants’ pathways and impact, and 3)mitigation or elimination of negative biological effects, including the spread of non-communicable endemic diseases.
At this session, participants are invited to present their new data on soil pollution, as well as to show ideas and approaches to the solution of the problem of soil reclamation, to show results that contribute to modern knowledge on the ecological and geochemical assessment of various regions of the world exposed to anthropic geochemical impact, including industrial pollution, transport, mining and use of fertilizers and biocides. We also welcome presentations devoted to methodological problems on soil pollution assessment, the creation of ecological and geochemical databases, and compiling risk maps. We hope that live discussion will contribute to each study.

Geoscience and health during the Covid-19 pandemic
The virus is still with us, with more potent variants. It remains the most immediate challenge for geosciences and health, including its impacts on geoscience development (data collection, training, dissemination) and the achievement of the UN Sustainable Development Goals, in particular that urban systems should increase well-being and health.
Long-term visions based on transdisciplinary scientific advances are therefore essential. As a consequence, this session, like the ITS1.1 session in 2021, calls for contributions based on data-driven and theory-based approaches to health in the context of global change. This includes :
- main lessons from lockdowns?
- how to get the best scientific results during a corona pandemic?
- how to manage field works, geophysical monitoring and planetary missions?
- qualitative improvements in epidemic modelling, with nonlinear, stochastic, and complex system science approaches;
- eventual interactions between weather and/or climate factors and epidemic/health problems
- new surveillance capabilities (including contact tracing), data access, assimilation and multidimensional analysis techniques;
- a fundamental revision of our urban systems, their greening and their need for mobility;
- a special focus on urban biodiversity, especially to better manage virus vectors;
- urban resilience must include resilience to epidemics, and therefore requires revisions of urban governance.

Advances in geomorphometry and landform mapping: possibilities, challenges and perspectives
Geomorphometry and landform mapping are important tools used for understanding landscape processes and dynamics on Earth and other planetary bodies. The recent rapid advances in technology and data collection methods have made available vast quantities of geospatial data offering unprecedented spatio-temporal range, density, and resolution, but it also created new challenges in terms of data processing and analysis.
This inter-disciplinary session on geomorphometry and landform mapping aims to bridge the gap between process-focused research fields and the technical domain where geospatial products and analytical methods are developed. The increasing availability of a wide range of geospatial datasets requires the continued development of new tools and analytical approaches as well as landform/landscape classifications. However, a potential lack of communication across disciplines results in efforts to be mainly focused on problems within individual fields. We aim to foster collaboration and the sharing of ideas across subject-boundaries, between technique developers and users, enabling us as a community to fully exploit the wealth of geospatial data that is now available.
We welcome perspectives on geomorphometry and landform mapping from ANY discipline (e.g. geomorphology, planetary science, natural hazard assessment, computer science, remote sensing). This session aims to showcase both technical and applied studies, and we welcome contributions that present (a) new techniques for collecting or deriving geospatial data products, (b) novel tools for analysing geospatial data and extracting innovative geomorphometric variables, (c) mapping and/or morphometric analysis of specific landforms as well as whole landscapes, and (d) mapping and/or morphometric analysis of newly available geospatial datasets. Contributions that demonstrate multi-method or inter-disciplinary approaches are particularly encouraged. We also actively encourage contributors to present tools/methods that are “in development”.

GI2 – Data networks and analysis
Programme group scientific officer:
Data fusion, integration, correlation and advances of non-destructive testing methods and numerical developments for engineering and geosciences applications
Non-destructive testing (NDT) methods are employed in a variety of engineering and geosciences applications and their stand-alone use has been greatly investigated to date. New theoretical developments, technological advances and the progress achieved in surveying, data processing and interpretation have in fact led to a tremendous growth of the equipment reliability, allowing outstanding data quality and accuracy.
Nevertheless, the requirements of comprehensive site and material investigations may be complex and time-consuming, involving multiple expertise and multiple equipment. The challenge is to step forward and provide an effective integration between data outputs with different physical quantities, scale domains and resolutions. In this regard, enormous development opportunities relating to data fusion, integration and correlation between different NDT methods and theories are to be further investigated.
This Session primarily aims at disseminating contributions from state-of-the-art NDT methods and new numerical developments, promoting the integration of existing equipment and the development of new algorithms, surveying techniques, methods and prototypes for effective monitoring and diagnostics. NDT techniques of interest are related–but not limited to–the application of acoustic emission (AE) testing, electromagnetic testing (ET), ground penetrating radar (GPR), geoelectric methods (GM), laser testing methods (LM), magnetic flux leakage (MFL), microwave testing, magnetic particle testing (MT), neutron radiographic testing (NR), radiographic testing (RT), thermal/infrared testing (IRT), ultrasonic testing (UT), seismic methods (SM), vibration analysis (VA), visual and optical testing (VT/OT).
The Session will focus on the application of different NDT methods and theories and will be related –but not limited to– the following investigation areas:
- advanced data fusion;
- advanced interpretation methods;
- design and development of new surveying equipment and prototypes;
- real-time and remote assessment and monitoring methods for material and site inspection (real-life and virtual reality);
- comprehensive and inclusive information data systems for the investigation of survey sites and materials;
- numerical simulation and modelling of data outputs with different physical quantities, scale domains and resolutions;
- advances in NDT methods, numerical developments and applications (stand-alone use of existing and state-of-the-art NDTs).
Geoscience problems related to massive release of radioactive materials by nuclear accidents and other human activities
The session gathers geoscientific aspects such as dynamics, reactions, and environmental/health consequences of radioactive materials that are massively released accidentally (e.g., Chernobyl and Fukushima nuclear power plant accidents, wide fires, etc.) and by other human activities (e.g., nuclear tests).
The radioactive materials are known as polluting materials that are hazardous for human society, but are also ideal markers in understanding dynamics and physical/chemical/biological reactions chains in the environment. Thus, the radioactive contamination problem is multi-disciplinary. In fact, this topic involves regional and global transport and local reactions of radioactive materials through atmosphere, soil and water system, ocean, and organic and ecosystem, and its relations with human and non-human biota. The topic also involves hazard prediction and nowcast technology.
By combining 35 years (> halftime of Cesium 137) monitoring data after the Chernobyl Accident in 1986, 10 years dense measurement data by the most advanced instrumentation after the Fukushima Accident in 2011, and other events, we can improve our knowledgebase on the environmental behavior of radioactive materials and its environmental/biological impact. This should lead to improved monitoring systems in the future including emergency response systems, acute sampling/measurement methodology, and remediation schemes for any future nuclear accidents.
The following specific topics have traditionally been discussed:
(a) Atmospheric Science (emissions, transport, deposition, pollution);
(b) Hydrology (transport in surface and ground water system, soil-water interactions);
(c) Oceanology (transport, bio-system interaction);
(d) Soil System (transport, chemical interaction, transfer to organic system);
(f) Natural Hazards (warning systems, health risk assessments, geophysical variability);
(g) Measurement Techniques (instrumentation, multipoint data measurements);
(h) Ecosystems (migration/decay of radionuclides).
The session consists of updated observations, new theoretical developments including simulations, and improved methods or tools which could improve observation and prediction capabilities during eventual future nuclear emergencies. New evaluations of existing tools, past nuclear contamination events and other data sets also welcome.
Cryospheric Data Science and Artificial Intelligence: Opportunities and Challenges
Machine learning, artificial intelligence and big data approaches have recently emerged as key tools in understanding the cryosphere. These approaches are being increasingly applied to answer long standing questions in cryospheric science, including those relating to remote sensing, forecasting, and improving process understanding across Antarctic, Arctic and Alpine regions. In doing so, data science and AI techniques are being used to gain insight into system complexity, analyse data on unprecedented temporal and spatial scales, and explore much wider parameter spaces than were previously possible.
In this session we invite submissions that utilise data science and/or AI techniques that address research questions relating to glaciology, sea ice, permafrost and/or polar climate science. Approaches used may include (but are not limited to) machine learning, artificial intelligence, big data processing/automation techniques, advanced statistics, and innovative software/computing solutions. These could be applied to any (or combinations) of data sources including remote sensing, numerical model output and field/lab observations. We particularly invite contributions that apply techniques and approaches that reveal new insights into cryospheric research problems that would not otherwise be achievable using traditional methods, and those that discuss how or if approaches can be applied or adapted to other areas of cryospheric science. Given the rapid development of this field by a diverse group of international researchers, we convene this session to help foster future collaboration amongst session contributors, attendees, and international stakeholders and help address the most challenging questions in cryospheric science.

Long time-series of geophysical observations
Long term observations are of vital importance in the Earth Sciences, yet often difficult to pursue and fund. The distinction of a fluctuation from a long-term change in Earth processes is a key question to better understand processes within the Earth and in the Earth system. Likewise, it is a prerequisite for the assessment of the Earth's climate change as well as risk assessment. In order to distinguish fluctuations from a steady change, knowledge on the time variability of the signal itself and long term observations are required. Exemplarily, due to the decadal variability of sea level, reliable sea level trends can only be obtained after about sixty years of continuous observations. Reliable strain rates of deformation require a minimum of a decade of continuous data, due to ambient and anthropogenic factors leading to fluctuations. This session invites contributions demonstrating the importance of long term geophysical, geodynamic, oceanographic, geodetic, and climate observatories. Advances in sensors, instrumentation, monitoring techniques, analyses, and interpretations of data, or the comparison of approaches are welcome, with the aim to stimulate a multidisciplinary discussion among those dedicated to the accumulation, preservation and dissemination of data over decadal time scales or beyond. Studies utilizing novel approaches such as AI for analysis of long time series are very welcome. Likewise, studies that show the mutual transfer of knowledge of terrestrial and satellite observations are a topic of interest. With this session, we also would like to provide an opportunity to gather and exchange experiences for representatives from observatories both in Europe and worldwide.
Innovative and holistic approaches to prevent, assess and mitigate soil pollution: integrating natural solutions with advanced data analysis and digital tools
Soil pollution is a worldwide problem, which can result in a negative impact in (terrestrial) ecosystems, surface and groundwater, and the food chain. According to the European Commission, there are around 2.8 million soil pollution events contributing to soil pollution. Of these, 25 % have been identified and registered, but only 5% need mitigation strategies. In order to address soil pollution and develop preventive and mitigation strategies, it is necessary to invest in (i) the identification and characterization of these sites, from contaminant identification to ecosystem characterisation, and (ii) the identification of potential solutions. This requires linking new strategies (e.g. machine learning, artificial intelligence, digital data mapping) with natural solutions (e.g. soil-microorganisms-root-plant interaction). We welcome our colleagues to present their latest and ongoing findings and look forward to establishing new partnerships to create holist strategies that can help to prevent, assess and mitigate soil pollution consistently and swiftly.
Data assimilation techniques and applications in coastal and open seas
Since its inception, data assimilation has proven to be enormously useful in the most varied fields throughout the Earth Sciences. It is certainly essential in meteorology, where the short-range forecasts would otherwise be almost impossible. In oceanography, its development has been slower, partly due to the smaller number of continuous and stable observations, and partly due to the fewer studies that show the importance of ocean forecasts for societal benefit. However, recently, these techniques are used more and more widely, both in operational oceanography and to produce climate reconstructions. Although the techniques are similar to those used in the atmospheric field, they have to deal with particularities due to the different environment, where the boundary conditions, open and closed, have greater importance, and the sparsity of observations poses unique challenges.
In this session, we welcome contributions describing data assimilation techniques, both methodological and case studies, in the oceanographic field. We welcome presentations of new techniques or new types of observations that cover every aspect of data assimilation, including varied applications of data assimilation, both in coastal seas and the open ocean.

Strategies and Applications of AI and ML in a Spatiotemporal Context
Modern challenges of climate change, disaster management, public health and safety, resources management, and logistics can only be addressed through big data analytics. A variety of modern technologies are generating massive volumes of conventional and non-conventional geospatial data at local and global scales. Most of this data includes geospatial data components and are analysed using spatial algorithms. Ignoring the geospatial component of big data can lead to an inappropriate interpretation of extracted information. This gap has been recognised and led to the development of new spatiotemporally aware strategies and methods.
This session discusses advances in spatiotemporal machine learning methods and the softwares and infrastructures to support them.

Making Geoanalytical Data FAIR: Managing Data from Field to Laboratory to Archive to Publication
Globally, geoscience and research analytical laboratories collect ever increasing volumes of data: an acute challenge now is how to collate, store and make these data accessible in a standardised, interoperable and machine-accessible form that is FAIR. Many solutions today are bespoke and inefficient, lacking, for example, unique identification of samples, instruments, and data sets needed to trace the analytical history of the data; and there are few community agreed standards to facilitate sharing and interoperability between systems.
The push for a solution is being driven by publishers and journals who increasingly require researchers to provide access to the supporting data from a trusted repository prior to publication of manuscripts or finalisation of grants. We urgently need community development of systems to facilitate easy and efficient management of geoanalytical laboratory data. We need to address the lack of global standards, best practices and protocols for analytical data management and exchange, in order for scientists to better share their data in a global network of distributed databases. Buy-in from users and laboratory managers/technicians is essential in order to develop efficient and supported mechanisms.
This session seeks a diversity of papers from any initiative around the world that organises and structures sample/field metadata and research laboratory data at any scale to facilitate sharing and processing of geoanalytical data. We welcome papers on data and metadata standardisation efforts and papers on data management and systems that transfer data/metadata from instruments to shared data systems and relevant persistent repositories. Efforts on how to collate, curate, share and publicise sample/data collections as well as papers on the social dynamics of building sharing systems/frameworks are also welcome.

geophysical imaging, modelling and inversion using active- and
passive-source seismic measurements as well as other geophysical
techniques (e.g., gravity, magnetic and electromagnetic) to
investigate properties of the Earth’s lithosphere and asthenosphere,
and explore the processes involved. We invite contributions focused on
methodological developments, theoretical aspects, and applications.
Studies across the scales and disciplines are particularly welcome.

gnssrefl: an open source GNSS reflections software package for measuring snow accumulation and water levels
We have developed an open source software package in python for ground-based GNSS reflections – gnssrefl (https://github.com/kristinemlarson/gnssrefl). This new software supports geoscientists wishing to measure in situ snow accumulation, permafrost melt, firn density, tides, and lake/river levels. We have developed videos (hosted on youtube) to help new users understand both the basic concepts of GNSS reflections and how to install and run the gnssrefl code. More than a dozen use cases are available online; Jupyter Notebooks have been developed as well. We envision the EGU tutorial session to be hands-on and interactive, with a focus on demonstrating the gnssrefl software and online tools (https://gnss-reflections.org), examining and discussing environmental results derived from GNSS data taken from public archives, and analyzing new datasets suggested by the students.
Advanced geostatistics for water, earth and environmental sciences
Geostatistical methods are commonly applied in the Water, Earth and Environmental sciences to quantify spatial variation, produce interpolated maps with quantified uncertainty and optimize spatial sampling designs. Space-time geostatistics explores the dynamic aspects of environmental processes and characterise the dynamic variation in terms of correlations. Geostatistics can also be combined with machine learning and mechanistic models to improve the modelling of real-world processes and patterns. Such methods are used to model soil properties, produce climate model outputs, simulate hydrological processes, and to better understand and predict uncertainties overall. Big data analysis and data fusion have become major topics of research due to technological advances and the abundance of new data sources from remote and proximal sensing as well as a multitude of environmental sensor networks. Methodological advances, such as hierarchical Bayesian modeling, machine learning, sparse Gaussian processes, local interaction models, as well as advances in geostatistical software modules in R and Python have enhanced the geostatistical toolbox.
This session aims to provide a forum where scientists from different disciplines can present and discuss innovative geostatistical methods targeting important problems in the Water, Earth and Environmental sciences. We also encourage contributions focusing on real-world applications of state-of-the-art geostatistical methods.
The topics of interest include:
1) Space-time geostatistics for hydrology, soil, climate system observations and modelling
2) Hybrid methods: Integration of geostatistics with optimization and machine learning approaches
3) Advanced parametric and non-parametric spatial estimation and prediction techniques
4) Big spatial data: analysis and visualization
5) Optimisation of spatial sampling frameworks and space-time monitoring designs
6) Algorithms and applications on Earth Observation Systems
7) Data Fusion, mining and information analysis
8) Geostatistical characterization of uncertainties and error propagation
9) Bayesian geostatistical analysis and hierarchical modelling
10) Functional data analysis approaches to geostatistics
11) Multiple point geostatistics

Remote sensing big data analysis and applications in geosciences
Remote sensing techniques, such as radar (e.g., synthetic aperture radar - SAR), optical, Lidar and hyperspectral imagery, together with hydroclimatic, geological, and geophysical data, as well as in-situ observations, have been widely employed for monitoring, and responding to natural and anthropogenic hazards and assessing environmental resources. Especially with the unprecedented spatio-temporal resolution and the rapid accumulation of remote sensing data collections from various spaceborne and airborne missions, we have much more opportunities to exploit hazard- and environmental- related signals, to classify the associated spatio-temporal surface changes such as deformations and landform alterations, and to interpret the primary and secondary driving mechanisms. Yet, when archiving, processing, and analyzing abundant remote sensing data, the ad hoc artificial intelligence (AI), like machine/deep learning and computer vision, is urgently required.
In this session, we welcome contributions that focus on new AI-based algorithms to retrieve remote sensing products related to environmental resources and hazards in an accurate, automated, and efficient framework. We particularly welcome contributions for applications in (1) mining, oil/gas production, fluid injection/extraction, civil infrastructure, sinkholes, land degradation, peatlands, glaciers, permafrost, and coastal subsidence; (2) emergency response based on remote sensing data to landslides, floods, winter storms, wildfires, pandemics, earthquakes, and volcanoes; and (3) mathematical and physical modeling of the remote sensing products for a better understanding on the surface and subsurface processes.
Very high resolution proximal remote sensing applications for natural hazards processes and impacts analysis and mitigation
The number of possible operative solutions currently adopted to study and monitor natural hazards processes has progressively increased in the last decades. Nowadays, UAV (Uncrewed Aerial Vehicles), terrestrial radar interferometry, and terrestrial digital photogrammetry are among the most diffuse systems adopted to identify precursor elements for detailed hazard assessment and support decision-makers during emergencies.
In particular, the use of these systems is very useful for creating high-resolution 3D models of the study area and monitoring natural hazards processes. The adoption of multi-scale and multi-sensor approaches can be beneficial for studying the same phenomenon from different points of view and can support a detailed description of the studied process and the most critical parameters that can be adopted for its characterization. The availability of many technical solutions represents an additional value, but the lack of defined methodologies can limit these systems' standardized use, particularly during emergencies.
This session aims to explore the use of proximal remote sensing systems in different scenarios related to natural hazards, from the preliminary characterization of possible (dangerous?) processes and the evaluation of the level of risk to the management of the emergency phase and the support of recovery and post-emergency reconstruction.
Interferometric Synthetic Aperture Radar added value products for Natural & Anthropogenic hazard assessment at local, regional and national scale.
Synthetic aperture radar (SAR) remote sensing is an established tool for natural and anthropogenic hazards mapping and monitoring. The new generation of radar satellite constellations along with a consistent repository of historical observations is fostering comprehensive multi-sensor hazard analyses. New constellations’ capabilities rely on innovative techniques based on high-resolution/wide-swath and short-temporal Interferometric SAR (InSAR). While acknowledging the benefits brought by these recent developments, the scientific community is now defining a new paradigm of techniques capable of: extracting relevant information from SAR imagery, designing proper methodologies for specific hazards, managing large SAR datasets (e.g. National ground motion services, Copernicus EGMS), and integrating radar data with multispectral satellite observations.

Remote Sensing and GIS for climate-related hazards in natural and man-made environments
The increase in recent decades of the occurrence of climate-related hazards and the subsequent consequences has been driven by climate change, the increasing human activities and infrastructure development, particularly in vulnerable areas. In order to reduce the damages and/or losses, more efforts should be directed towards effective disaster risk management, with a focus on hazard, vulnerability and elements-at-risk mapping.
Remote Sensing (RS) and Geographic Information Systems (GIS) have been proved to be powerful tools in monitoring, and mapping change and rate of change in relation to hydrological hazards, particularly in data scarce environments, thanks to the great advantage of sensing extended areas, at low cost and with regular revisit capability. Furthermore, it offers the opportunity to gain fresh insights into biophysical environments through the spatial, temporal, spectral and radiometric resolutions of satellite systems. The advantages of RS are further supported by the analytical and geospatial data integration capabilities of GIS.
The main goal of this session is to present the recent advancements and range of applications in the fields of hazard monitoring and early warning, using RS (active and passive sensors, Lidar, UAVs, thermal, etc.) supported by GIS for the successful assessment and management of climate-related hazards. In particular, this session intends to give the floor to novel studies and applications in the analysis of Earth Observation (EO) and other geospatial data for the detection, monitoring, modeling and mapping of phenomena such as floods, landslides, soil erosion, droughts, etc. Water resources management, urban and cultural heritage management, and agriculture adaptation to address extreme conditions will be thoroughly discussed.
The session aims to serve a diverse community of research scientists, practitioners, end-users and decision-makers. Early Career Scientists (ECS) are strongly encouraged to present their research.
Application of remote sensing and Earth-observation data in natural hazard and risk studies
Remote sensing and Earth Observations (EO) are used increasingly in the different phases of the risk management and in development cooperation, due to the challenges posed by contemporary issues such as climate change, and increasingly complex social interactions. The advent of new, more powerful sensors and more finely tuned detection algorithms provide the opportunity to assess and quantify natural hazards, their consequences, and vulnerable regions, more comprehensively than ever before.
Several agencies have now inserted permanently into their program the applications of EO data to risk management. During the preparedness and prevention phase, EO revealed, fundamental for hazard, vulnerability, and risk mapping. EO data intervenes both in the emergency forecast and early emergency response, thanks to the potential of rapid mapping. EO data is also increasingly being used for mapping useful information for planning interventions in the recovery phase, and then providing the assessment and analysis of natural hazards, from small to large regions around the globe. In this framework, Committee on Earth Observation Satellites (CEOS) has been working from several years on disasters management related to natural hazards (e.g., volcanic, seismic, landslide and flooding ones), including pilots, demonstrators, recovery observatory concepts, Geohazard Supersites, and Natural Laboratory (GSNL) initiatives and multi-hazard management projects.
The session is dedicated to multidisciplinary contributions focused on the demonstration of the benefit of the use of EO for natural hazards and risk management.
The research presented might focus on:
- Addressed value of EO data in hazard/risk forecasting models
- Innovative applications of EO data for rapid hazard, vulnerability and risk mapping, the post-disaster recovery phase, and in support of disaster risk reduction strategies
- Development of tools for assessment and validation of hazard/risk models
The use of different types of remote sensing (e.g. thermal, visual, radar, laser, and/or the fusion of these) is highly recommended, with an evaluation of their respective pros and cons focusing also on future opportunities (e.g. new sensors, new algorithms).
Early-stage researchers are strongly encouraged to present their research. Moreover, contributions from international cooperation, such as CEOS and GEO initiatives, are welcome.

Novel data, methods and applications in Geomorphometry
Geomorphometry, a science of quantitative land surface analysis, gathers various mathematical, statistical and image processing techniques to quantify morphological, hydrological, ecological and other aspects of a land surface. The typical input to geomorphometric analysis is a square-grid representation of the land surface: a digital elevation model (DEM) or one of its derivatives. DEMs provide the backbone for many studies in Geo sciences, hydrology, land use planning and management, Earth observation and natural hazards.
One topic of active research concerns compromises between the use of global DEMs at 1-3 arc second, ~30-90 m grid spacing, and local LiDAR/structure from motion (SFM) elevation models at 1 m or finer grid spacing. Point clouds from LiDAR, either ground-based or from airborne vehicles, are a generally accepted reference tool to assess the accuracy of other DEMs. SFM data have a resolution comparable to LiDAR point clouds, but can cost significantly less to acquire for smaller areas. Globally available DEMS include the recently published Copernicus GLO-90 and GLO-30. This session provides an exciting forum to show the potential applications of this new DEM and its improvements over SRTM. We would like to investigate the tradeoff between the employment of the two kinds of data, and applications which can benefit from data at both (local and global) scales.
The improvements in the global DEMs, as well as the increasing availability of much finer resolution LiDAR and SFM DEMs, call for new analytical methods and advanced geo-computation techniques, necessary to cope with diverse application contexts. We aim at investigating new methods of analysis and advanced geo-computation techniques, including high-performance and parallel computing implementations of specific approaches.
Commercial applications of DEM data and of geomorphometric techniques can benefit important business sectors. Besides a proliferation of applications that can tolerate low accuracy geographical data and simple GIS applications, a large base of professionals use high-resolution, high-accuracy elevation data and high-performance GIS processing. We would like to survey and investigate professional, commercial and industrial applications, including software packages, from small enterprises to large companies, to ascertain how academic researchers and industry can work together.

Lidar remote sensing of the atmosphere
This session invites contributions on the latest developments and results in lidar remote sensing of the atmosphere, covering • new lidar techniques as well as applications of lidar data for model verification and assimilation, • ground-based, airborne, and space-borne lidar systems, • unique research systems as well as networks of instruments, • lidar observations of aerosols and clouds, thermodynamic parameters and wind, and trace-gases. Atmospheric lidar technologies have shown significant progress in recent years. While, some years ago, there were only a few research systems, mostly quite complex and difficult to operate on a longer-term basis because a team of experts was continuously required for their operation, advancements in laser transmitter and receiver technologies have resulted in much more rugged systems nowadays, many of which are already operated routinely in networks and some even being automated and commercially available. Consequently, also more and more data sets with very high resolution in range and time are becoming available for atmospheric science, which makes it attractive to consider lidar data not only for case studies but also for extended model comparison statistics and data assimilation. Here, ceilometers provide not only information on the cloud bottom height but also profiles of aerosol and cloud backscatter signals. Scanning Doppler lidars extend the data to horizontal and vertical wind profiles. Raman lidars and high-spectral resolution lidars provide more details than ceilometers and measure particle extinction and backscatter coefficients at multiple wavelengths. Other Raman lidars measure water vapor mixing ratio and temperature profiles. Differential absorption lidars give profiles of absolute humidity or other trace gases (like ozone, NOx, SO2, CO2, methane etc.). Depolarization lidars provide information on the shapes of aerosol and cloud particles. In addition to instruments on the ground, lidars are operated from airborne platforms in different altitudes. Even the first space-borne missions are now in orbit while more are currently in preparation. All these aspects of lidar remote sensing in the atmosphere will be part of this session.

Open session on atmosphere, land and ocean monitoring
The Open Session on atmosphere, land and ocean monitoring aims at presenting highlights of recent results obtained through observations and modelling as well as relevant reviews in these fields.
We shall connect with Earth Observations programmes at ESA, EU and worldwide, using new satellites and oberving platforms, as well as new techniques for distributing, merging and analysing EO data using AI.
The session is intended as an open forum for interdisciplinary discussion between representatives of different fields. Thus, we welcome especially overarching presentations which may be interesting to a wider community.
Observations are one major link to get an overall picture of processes within the Earth environment during measurement campaigns. This includes application to derive atmospheric parameters, surface properties of vegetation, soil and minerals and dissolved or suspended matter in inland water and the ocean. Ground based systems and data sets from ships, aircraft and satellites are key information sources to complement the overall view. All of these systems have their pros and cons, but a comprehensive view of the observed system is generally best obtained by means of a combination of all of them.
The validation of operational satellite systems and applications is a topic that has come increasingly into focus with the European Copernicus program in recent years. The development of smaller state-of-the-art instruments, the combination of more and more complex sets of instruments simultaneously on one platform, with improved accuracy and high data acquisition speed together with high accuracy navigation and inertial measurements enables more complex campaign strategies even on smaller aircraft or unmanned aerial vehicles (UAV).
This session will bring together a multidisciplinary research community to present:
• Atmosphere-land-ocean (or inland water) system modelling and validation
• new instruments (Lidar, etc), platforms (UAV etc.), setups and use in multidisciplinary approaches
• Larger scale in-situ and remote sensing observation networks from various platforms (ground based, airborne, ship-borne, satellite)
• recent field campaigns and their outcomes
• (multi-) aircraft campaigns
• satellite calibration/validation campaigns
• sophisticated instrument setups and observations
• advanced instrument developments
• UAV applications

Ground Penetrating Radar: Applications and Advancements
The never-ending growth of the ground penetrating radar applications reserves continuously small and less small discoveries, and deserves a space for discussion and reciprocal listening also at the EGU conference.
The pandemic has meaningfully hindered many activities but to our knowledge not too much the interest in the GPR instrumentation and technique at an applicative level, even if exchanges of experiences at international conferences have been of course necessarily reduced. So, we hope that this session can meet the interest of many researchers, professionals, PhD students as well skilled GPR users as geologists, engineers, geophysicists and possibly archaeologists and architects.
Contributions are welcome with regard to all the aspects of the GPR technique, ranging from the hardware of the systems to the data processing and any theoretical aspect, including innovative applications or procedures as well as results of particular relevance, possibly achieved within an integrated measurement campaign including also different data.
Hope to see you in Vienna.

Geo-infrastructure monitoring: complex data analysis and instrument application
Continues monitoring of infrastructure systems are essential to ensure a reliable movement of people and goods, which involves in the economy growth and human interaction. The wide variety of instruments available allows diverse applications to increase data availability for a better understanding of geotechnical surroundings which are directly linked to the safe operation of infrastructures to prevent catastrophise such as soil erosion, settlements, liquefaction, landslides, seismic activities, flooding and even wildfires close to the highways. Understanding mentioned events are vital to provide a safe infrastructure in extreme climate conditions. This session focus on the application of geosciences and geophysical instrumentation including sensors on the infrastructures monitoring and data analysis from critical infrastructures (e.g., roadways, railway system, bridges, tunnels, water supply, underground utilities, electrical grids, and other embedded facilities in cities). The session aims to increase knowledge on geo-infrastructure management to overcome future challenges associated with the societal and human interaction, present advance knowledge research and novel approaches from various disciplines with a vibrant interaction to economy and human-interaction studies to provide an efficient infrastructure management system. The session is considered inter-and transdisciplinary (ITS) session. The applications and topics include but are not limited to: (1) Advance knowledge of the destructive and non-destructive geoscience and geophysical techniques including contactless and non-contactless techniques such as sensors. (2) Intelligent data analysis approaches to analyse accurate and precise interpretation of big data sets driven from various technologies (e.g., computer vision and image, and signal processing). (3) Influence of the surrounding areas on infrastructure management systems linked to natural events such as soil erosion, settlements, liquefaction, landslides, seismic activities, flooding, wildfires and extreme weather condition. (4) Continuous real-time monitoring to provide smart tools such as an integration of geosciences data with BIM models, Internet of Things, digital twins, robotic monitoring, artificial intelligence, automation systems based on machine learning and computational modelling for better decision-making for infrastructure owner/operators. (5) Human-interaction computer-based aided to generate reliable infrastructures.
Characterizing Submarine Active Faults: From Local and Regional Observations and Monitoring to Seismic Hazard Characterization
Since the beginning of the XXI Century, our society has witnessed a number of catastrophic offshore earthquakes with devastating consequences (e.g., Sumatra 2004, Japan 2010, Palu 2018 or Samos-Izmir 2020). Localizing the offshore active faults and understanding their earthquake history is key to improve modern probabilistic seismic hazard assessment (PSHA) and, thus, to be able to mitigate the consequences of future offshore events.
In the last few years, the development of new geological and geophysical instrumentation has made possible the acquisition of offshore data at various scales with unprecedented detail and resolution, as for example deep and shallow boreholes, wide-angle seismic profiles, tomography, 3D and 2D seismic reflection surveys, or ultra-high-resolution bathymetry. In addition, these instrumentation is also allowing to carry on long-term monitoring (i.e., seismology, seafloor geodesy or pore pressure) and repeat surveys (i.e., time-lapse bathymetry). These new data is leading to achieve major advances in the study of active faults in offshore areas and the characterization of their recent activity, seismogenic potential and related secondary effects (i.e., mass wasting).
The aim of this session is to compile studies that focus on the use of geological and geophysical data to identify offshore active structures, to quantify the deformation that they are producing in the seafloor, to evaluate their seismogenic and tsunamigenic potential, to characterize possibly related secondary effects such as submarine mass transport deposits, and to estimate the related hazards. Accordingly, we welcome studies and/or new perspectives and ideas in marine active tectonics, turbidite paleoseismology, offshore on-fault paleoseismology or tectonic geomorphology, and seismotectonics, from local to regional scale analysis. We also encourage the submission of studies that explore the application of new ideas to estimate coseismic seafloor deformation, to constrain earthquake timing, long-term offshore monitoring of active structures, as well as the application of fault geometrical and kinematic reconstruction to seismic and tsunami hazard analysis.

Advances in fiber-optic sensing technologies for geophysical applications
Recently, there have been significant breakthroughs in the use of fiber-optic sensing techniques to interrogate cables at high precision both on land and at sea as well as in boreholes and at the surface. Laser reflectometry using both fit-to-purpose and commercial fiber-optic cables have successfully detected a variety of signals including microseism, local and teleseismic earthquakes, volcanic events, ocean dynamics, etc. Other laser-based techniques can be used to monitor distributed strain, temperature, and even chemicals at a scale and to an extent previously unattainable with conventional geophysical methods.
We welcome any contributions to recent development in the fields of applications, instrumentation, and theoretical advances for geophysics with fiber-optic sensing techniques. These may include - but are not limited to - application of fiber-optic cables or sensors in seismology, geodesy, geophysics, natural hazards, oceanography, urban environment, geothermal application, etc. with an emphasis on laboratory studies, large-scale field tests, and modeling. We also encourage contributions on data analysis techniques, machine learning, data management, instruments performances and comparisons as well as new experimental field studies.
Geophysical and in situ methods for snow and ice studies
Geophysical and in-situ measurements offer important baseline datasets, as well as validation for modelling and remote sensing products. They are used to advance our understanding of firn, ice-sheet and glacier dynamics, sea ice processes, changes in snow cover and snow properties, snow/ice-atmosphere-ocean interactions, permafrost degradation, geomorphic mechanisms and changes in englacial and subglacial condition.
In this session we welcome contributions related to a wide spectrum of methods, including, but not limited to, advances in radioglaciology, active and passive seismology, geoelectrics, acoustic sounding, fiber-optic sensing, GNSS reflectometry, signal attenuation and time delay techniques, cosmic ray neutron sensing, ROV and drone applications, and electromagnetic methods. Contributions could be related to field applications, new approaches in geophysical or in-situ survey techniques, or theoretical advances in data analysis processing or inversion. Case studies from all parts of the cryosphere such as snow and firn, alpine glaciers, ice sheets, glacial and periglacial environments, permafrost, or sea ice, are highly welcome.
The focus of the session is to compare experiences in the application, processing, analysis and interpretation of different geophysical and in-situ techniques in these highly complex environments. We have been running this session for nearly a decade and it always produces lively and informative discussion. This session is offered as a fully hybrid vPICO: an engaging presentation format in which all authors will present their research orally as a quick-fire 2-minute overview, and then further present and discuss their research.

Short-term Earthquakes Forecast (StEF) and multi-parametric time-Dependent Assessment of Seismic Hazard (t-DASH)
From the real-time integration of multi-parametric observations is expected the major contribution to the development of operational t-DASH systems suitable for supporting decision makers with continuously updated seismic hazard scenarios. A very preliminary step in this direction is the identification of those parameters (seismological, chemical, physical, biological, etc.) whose space-time dynamics and/or anomalous variability can be, to some extent, associated with the complex process of preparation of major earthquakes.
This session wants then to encourage studies devoted to demonstrate the added value of the introduction of specific, observations and/or data analysis methods within the t-DASH and StEF perspectives. Therefore, studies based on long-term data analyses, including different conditions of seismic activity, are particularly encouraged. Similarly welcome will be the presentation of infrastructures devoted to maintain and further develop our present observational capabilities of earthquake related phenomena also contributing in this way to build a global multi-parametric Earthquakes Observing System (EQuOS) to complement the existing GEOSS initiative.
To this aim this session is not addressed just to seismology and natural hazards scientists but also to geologist, atmospheric sciences and electromagnetism researchers, whose collaboration is particular important for fully understand mechanisms of earthquake preparation and their possible relation with other measurable quantities. For this reason, all contributions devoted to the description of genetic models of earthquake’s precursory phenomena are equally welcome.
Rockfalls, rockslides and rock avalanches are among the primary hazards and drivers of landscape evolution in steep terrain. The physics of rock slope degradation and dynamics of failure and transport mechanisms define the hazards and possible mitigation strategies and enable retrodictions and predictions of events and controls.
This session aims to bring together state-of-the-art methods for predicting, assessing, quantifying, and protecting against rock slope hazards across spatial and temporal scales. We seek innovative contributions from investigators dealing with all stages of rock slope hazards, from weathering and/or damage accumulation, through detachment, transport and deposition, and finally to the development of protection and mitigation measures. In particular, we seek studies presenting new theoretical, numerical or probabilistic modelling approaches, novel data sets derived from laboratory, in situ, or remote sensing applications, and state-of-the-art approaches to social, structural, or natural protection measures. We especially encourage contributions from geomechanics/rock physics, geodynamics, geomorphology and tectonics to better understand how rockfall, rockslides and rock avalanches act across scales.

Towards reliable Landslide Early Warning Systems
Among the many mitigation measures available for reducing the risk to life related to landslides, early warning systems certainly constitute a significant option available to the authorities in charge of risk management and governance. Landslide early warning systems (LEWS) are non-structural risk mitigation measures applicable at different scales of analysis: slope and regional.
Independently by the scale of analysis, the structure of LEWS can be schematized as an interrelation of four main modules: setting, modelling, warning, response. However, the definition of the elements of these modules and the aims of the warnings/alerts issued considerably vary as a function of the scale at which the system is employed.
The session focuses on landslide early warning systems (LEWSs) at both regional and local scales. The session wishes to highlight operational approaches, original achievements and developments useful to operate reliable (efficient and effective) local and territorial LEWS. Moreover, the different schemes describing the structure of a LEWS available in literature clearly highlight the importance of both social and technical aspects in the design and management of such systems.
For the above-mentioned reasons, contributions addressing the following topics are welcome:
• rainfall thresholds definition for warning purposes;
• monitoring systems for early warning purposes;
• warning models for warning levels issuing;
• performance analysis of landslide warning models;
• communication strategies;
• emergency phase management;

The role of temperature in landslide monitoring, activity, and dynamics
Temperature and heat transfers can affect the hydraulic and mechanical properties of soils and rocks in multiple ways. Heat dissipation by friction can control the runout of landslides via strengthening or weakening mechanisms. Surface and deep temperatures can inform on geomaterial properties and structures, and can be used to enhance monitoring data and warning systems. Thermal inputs from the surface to the subsurface can affect the stability of slopes, even in temperate and warm regions. Climatic forcing in the short and long terms (e.g., driven by climate change) can alter landslide patterns and trends in response to thermo-hydro-mechanical processes.
In this session, we aim to bring together scientists interested in all aspects of landslide thermo-hydro-mechanics, from experimental studies to field and remote-sensing monitoring, from microstructural analyses to geomechanical and geostatistical modelling at various spatial and temporal scales.
The session is organized in cooperation with NhET (Natural hazard Early career scientists Team).
The 2021 eruption of Cumbre Vieja volcano (Canary Islands)
This session is devoted to the most recent eruption of the Cumbre Vieja volcano, which started on Sept. 19, 2021, on the island of La Palma after 50 years of repose. Volcanic unrest was recorded in Oct. 2017, when a seismic swarm was located at more than 20 km depths. Nine additional swarms followed, the last one was recorded in June 2021. Geochemical anomalies followed this increased seismicity indicating a magmatic recharge at depth. On Sept. 11, 2021, a new seismic swarm was observed at shallower depths (10-12 km), indicating a possible magmatic intrusion. This was confirmed when geodetic monitoring networks on the island started showing clear signs of inflation. The seismicity increased in frequency and intensity with many felt earthquakes. Seismic activity accelerated in the morning of Sept. 19 when a strong shallow earthquake was widely felt on the western part of the island. This was the precursor of the eruption, which started at about 14:10 UTC on the same day. A series of vents opened along a fissure close to Los Llanos on the western flank of Cumbre Vieja volcano. The eruption displayed vigorous lava fountaining and powerful Strombolian explosions while lava effusion produced a compound Aa flow field. The eruption has destroyed hundreds of buildings, plantations as well as cutting vital transport routes.
This session is open to contributions aimed at geological, geophysical, geochemical and volcanological studies of the eruption and its precursors and, more in general, to studies that can help better understanding the eruptive dynamics. We also welcome contributions focused on the management of scientific communication during this crisis and the management of the volcanic emergency.

Assessing and monitoring geomorphic processes across scales
Transport of sediments in geophysical flows occurs in mountainous, fluvial, estuarine, coastal, aeolian and other natural or man-made environments on Earth, while also shapes the surface of planets such as Mars, Titan, and Venus. Understanding the motion of sediments is still one of the most fundamental problems in hydrological and geophysical sciences. Such processes can vary across a wide range of scales - from the particle to the landscape - which can directly impact both the form (geomorphology) and, on Earth, the function (ecology and biology) of natural systems and the built infrastructure surrounding them. In particular, feedback between flow and sediment transport as well as interparticle interactions including size sorting are a key processes in surface dynamics, finding a range of important applications, from hydraulic engineering and natural hazard mitigation to landscape evolution and river ecology.
Specific topics of interest include (but are not restricted to):
A) particle-scale interactions and transport processes:
-mechanics of entrainment and disentrainment (for fluvial and aeolian flows)
-momentum (turbulent impulses) and energy transfer between turbulent flows and particles
-upscaling and averaging techniques for stochastic transport processes
-interaction among grain sizes in poorly sorted mixtures, including particle segregation
B) reach-scale sediment transport and geomorphic processes
-bedform generation, evolution and disintegration dynamics (e.g. for dunes and other formations)
-discrete element modelling of transport processes and upscaling into continuum frameworks
-derivation and solution of equations for multiphase flows (including fluvial and aeolian flows)
-shallow water hydro-sediment-morphodynamic processes
C) large-scale, highly unsteady and complex water-sediment flows:
-flash floods, debris flows and landslides due to extreme rainfall
-natural and build dam failures and compound disasters (due to landslides, debris flow intrusion and downstream flooding)
-reservoir operation schemes and corresponding fluvial processes
-design of hydraulic structures such as fish passages, dam spillways, also considering the impact of sediment
-dredging, maintenance and regulation for large rivers and navigational waterways
New approaches for monitoring and modelling sediment transport
Sediment transport is a fundamental component of all geomorphic systems (including fluvial, aeolian, coastal, hillslopes and glacial), yet it is something that we still find surprisingly difficult both to monitor and to model. Robust data on where and how sediment transport occurs are needed to address outstanding research questions, including the spatial and temporal controls on critical shear stress, the influence of varying grain size distributions, and the impact of large magnitude events. Recent developments have provided a) new opportunities for measuring sediment transport in the field; and b) new ways to represent sediment transport in both physical laboratory models and in numerical models. These developments include (but are not limited to) the application of techniques such as seismic and acoustic monitoring, 3D imaging (e.g. CT and MRI scanning), deployment of sensors such as accelerometers, replication of field topography using 3D printing, use of luminescence as a sediment tracer, remote sensing of turbidity, discrete numerical modelling, and new statistical approaches.
In this session we welcome contributions from all areas of geomorphology that develop new methods for monitoring and modelling all types of sediment transport, or that showcase an application of such methods. Contributions from ECRs and underrepresented groups are particularly encouraged.

Remote sensing for environmental monitoring
Remote sensing measurements, acquired using different platforms - ground, UAV, aircraft and satellite - have increasingly become rapidly developing technologies to study and monitor Earth surface, to perform comprehensive analysis and modeling, with the final goal of supporting decision systems for ecosystem management. The spectral, spatial and temporal resolutions of remote sensors have been continuously improving, making environmental remote sensing more accurate and comprehensive than ever before. Such progress enables understanding of multiscale aspects of high-risk natural phenomena and development of multi-platform and inter-disciplinary surveillance monitoring tools. The session welcomes contributions focusing on present and future perspectives in environmental remote sensing, from multispectral/hyperspectral optical and thermal sensors. Applications are encouraged to cover, but not limited to, the monitoring and characterization of environmental changes and natural hazards from volcanic and seismic processes, landslides, and soil science. Specifically, we are looking for novel solutions and approaches including the topics as follows: (i) state-of-the-art techniques focusing on novel quantitative methods; (ii) new applications for state-of-the-art sensors, including UAVs and other close-range systems; (iii) techniques for multiplatform data fusion.
Airborne observations in multidisciplinary environmental research using European Research Infrastructures; observations, campaigns and future plans
Observations from aircraft, remotely piloted aircraft systems (RPAS/UAV/UAS) and balloons are an important means to obtain a broad view of processes within the Earth environment during measurement campaigns. The range of available instruments enables a broad and flexible range of applications. It includes sensors for meteorological parameters, trace gases and cloud/aerosol particles and more complex systems like high spectral resolution lidar, hyperspectral imaging at wavelengths from the visible to thermal infra-red, solar-induced fluorescence and synthetic aperture radar. The use of small state-of-the-art instruments, the combination of more and more complex sets of instruments with improved accuracy and data acquisition speed enables more complex campaign strategies even on small aircraft, balloons or RPAS.
Applications include atmospheric parameters, structural and functional properties of vegetation, glaciological processes, sea ice and iceberg studies, soil and minerals and dissolved or suspended matter in inland water and the ocean. Ground based systems and satellites are key information sources to complement airborne datasets and a comprehensive view of the observed system is often obtained by combining all three. Aircraft and balloon operations depend on weather conditions either to obtain the atmospheric phenomenon of interest or the required surface-viewing conditions and so require detailed planning. They provide large horizontal and vertical coverage with adaptable temporal sampling. Future satellite instruments can be tested using airborne platforms during their development. The validation of operational satellite systems and applications using airborne measurements has come increasingly into focus with the European Copernicus program in recent years.
This session will bring together aircraft, balloon and RPAS operators and researchers to present:
• an overview of the current status of environmental research focusing on the use of airborne platforms
• recent observation campaigns and their outcomes
• multi-aircraft/balloon/RPAS and multi-RI campaigns
• using airborne and ground-based RI to complement satellite data, including cal/val campaigns
• identifying and closing capability gaps
• contributions of airborne measurements to modelling activities
• airborne platforms to reduce the environmental footprint of alternative observation strategies
• airborne instruments, developments and observations
• future plans involving airborne research

New frontiers of multiscale monitoring, analysis, modeling and decisional support (DSS) of environmental systems
Environmental systems often span spatial and temporal scales covering different orders of magnitude. The session is oriented toward collecting studies relevant to understand multiscale aspects of these systems and in proposing adequate multi-platform and inter-disciplinary surveillance networks monitoring tools systems. It is especially aimed to emphasize the interaction between environmental processes occurring at different scales. In particular, special attention is devoted to the studies focused on the development of new techniques and integrated instrumentation for multiscale monitoring of high natural risk areas, such as volcanic, seismic, energy exploitation, slope instability, floods, coastal instability, climate changes, and another environmental context.
We expect contributions derived from several disciplines, such as applied geophysics, geology, seismology, geodesy, geochemistry, remote and proximal sensing, volcanology, geotechnical, soil science, marine geology, oceanography, climatology, and meteorology. In this context, the contributions in analytical and numerical modeling of geological and environmental processes are also expected.
Finally, we stress that the inter-disciplinary studies that highlight the multiscale properties of natural processes analyzed and monitored by using several methodologies are welcome.

Cosmic rays across scales and disciplines: the new frontier in environmental research
Cosmic rays carry information about space and solar activity, and, once near the Earth, they produce isotopes, influence genetic information, and are extraordinarily sensitive to water. Given the vast spectrum of interactions of cosmic rays with matter in different parts of the Earth and other planets, cosmic-ray research ranges from studies of the solar system to the history of the Earth, and from health and security issues to hydrology and climate change.
Although research on cosmic-ray particles is connected to a variety of disciplines and applications, they all share similar questions and problems regarding the physics of detection, modeling, and the influence of environmental factors.
The session brings together scientists from all fields of research that are related to monitoring and modeling of cosmogenic radiation. It will allow sharing of expertise amongst international researchers as well as showcase recent advancements in their field. The session aims to stimulate discussions about how individual disciplines can share their knowledge and benefit from each other.
We solicit contributions related but not limited to:
- Health, security, and radiation protection: cosmic-ray dosimetry on Earth and its dependence on environmental and atmospheric factors
- Planetary space science: satellite and ground-based neutron and gamma-ray sensors to detect water and soil constituents
- Neutron and Muon monitors: detection of high-energy cosmic-ray variations and its dependence on local, atmospheric, and magnetospheric factors
- Hydrology and climate change: low-energy neutron sensing to measure water in reservoirs at and near the land surface, such as soils, snow pack, and vegetation
- Cosmogenic nuclides: as tracers of atmospheric circulation and mixing; as a tool in archaeology or glaciology for dating of ice and measuring ablation rates; and as a tool for surface exposure dating and measuring rates of surficial geological processes
- Detector design: technological advancements for the detection of cosmic rays
- Cosmic-ray modeling: advances in modeling of the cosmic-ray propagation through the magnetosphere and atmosphere, and their response to the Earth's surface
- Impact modeling: How can cosmic-ray monitoring support environmental models, weather and climate forecasting, irrigation management, and the assessment of natural hazards

Geoscience applications of environmental radioactivity
Natural radioactivity is ubiquitous in the environment as a result of i) cosmic radiation from space and secondary radiation from the interaction of cosmic rays with the atmosphere, ii) terrestrial sources from soils and rocks and particularly Potassium, Uranium and Thorium and their decay products among which Radon gas stands out. Artificial radionuclides from nuclear and radiation accidents and incidents makes up an additional contribution to the environmental radioactivity.
Nuclear techniques enable the measurement of radioactivity in air, soils and water even at trace levels, making it a particularly appealing tool for tracing time-varying environmental phenomena. This session welcomes contributions addressing the measurement and exploitation of environmental radioactivity in all areas of geosciences, including, but not limited to:
- geological and geomorphological surveys;
- mineral exploration;
- groundwater contamination;
- coastal and marine monitoring;
- soil erosion processes;
- Naturally Occurring Radioactive Materials (NORMs);
- geostatistical methods for radioactivity mapping;
- airborne and drones surveys;
- novel methods and instrumentations;
- atmospheric tracing, mixing and transport processes;
- public health including the EU BSS directive and Euratom-Drinking Water Directive

Geospatial analysis for sustainable development
The session “Geospatial analysis for sustainable development” welcomes submissions related to global or regional applications of geospatial data analysis techniques to address sustainability challenges (land, energy, water, climate, infrastructure, vegetation, health etc.) and their interactions. Contributions aiming at improving the understanding, planning, and evaluation of technological, environmental and policy solutions pursuing the achievement of one or more Sustainable Development Goals (SDGs) will be considered. The main methodological requirement is the use of GIS data (from earth observation, in-situ collection, or statistical offices) and manipulation tools to develop and apply innovative methodologies leveraging bottom-up, spatially-explicit information and highlighting their benefits vis-à-vis aggregated, top-down analysis. Preference will be given to studies which are broader in geographical scope, and which can be scaled to other contexts.
From historical images to modern high resolution topography: methods and applications in geosciences
Recent advances in image collection, e.g. using unoccupied aerial vehicles (UAVs), and topographic measurements, e.g. using terrestrial or airborne LiDAR, are providing an unprecedented insight into landscape and process characterization in geosciences. In parallel, historical data including terrestrial, aerial, and satellite photos as well as historical digital elevation models (DEMs), can extend high-resolution time series and offer exciting potential to distinguish anthropogenic from natural causes of environmental change and to reconstruct the long-term evolution of the surface from local to regional scale.
For both historic and contemporary scenarios, the rise of techniques with ‘structure from motion’ (SfM) processing has democratized data processing and offers a new measurement paradigm to geoscientists. Photogrammetric and remote sensing data are now available on spatial scales from millimetres to kilometres and over durations of single events to lasting time series (e.g. from sub-second to decadal-duration time-lapse), allowing the evaluation of event magnitude and frequency interrelationships.
The session welcomes contributions from a broad range of geoscience disciplines such as geomorphology, cryosphere, volcanology, hydrology, bio-geosciences, and geology, addressing methodological and applied studies. Our goal is to create a diversified and interdisciplinary session to explore the potential, limitations, and challenges of topographic and orthoimage datasets for the reconstruction and interpretation of past and present 2D and 3D changes in different environments and processes. We further encourage contributions describing workflows that optimize data acquisition and processing to guarantee acceptable accuracies and to automate data application (e.g. geomorphic feature detection and tracking), and field-based experimental studies using novel multi-instrument and multi-scale methodologies. This session invites contributions on the state of the art and the latest developments in i) modern photogrammetric and topographic measurements, ii) remote sensing techniques as well as applications, iii) time-series processing and analysis, and iv) modelling and data processing tools, for instance, using machine learning approaches.
