GI – Geosciences Instrumentation & Data Systems

GI1 – General sessions on geoscience instrumentation

GI1.1

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.

GI1.2

Environmental systems often span spatial and temporal scales covering different orders of magnitude. The session is oriented in 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, a special attention is devoted to the studies focused on the development of new techniques and integrated instrumentation for multiscale monitoring high natural risk areas, such as: volcanic, seismic, energy exploitation, slope instability, floods, coastal instability, climate changes and other 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.

ITS1.2/GI1.3 EDI

Corona pandemic significantly affected our livies and scientific activities. All institutions, both scientific and high-education, had to find their own tips to keep the science activities. Such knowledge is often common across different scientific disciplines. This session aims to exchange such know-how. The following topics are just examples and all related contributions are welcome.

(1) How can we meet the deadlines, particularly for planetary missions with limited launch window, under corona pandemic? What are the difference between different institution and how was the result?

(2) How can we mange field works and geophysical monitoring (e.g., maintenance of instruments on sites)?

(3) Non-uniform global distribution and its time profiles of the corona pandemic suggest some geophysical (not only geographical) factors. Does geophysical condition (gradient of UV, gradient of air temperature/humidity, wind) have any correlation to the pandemic?

(4) Can we apply our analyses method on corona data? Isn't it useful to apply our multi-dimension analyses, data assimilation of different sources of data, evaluation and correction of data (and its pipeline), fractal analyses of local distribution, etc?

(5) Air pollution that reflects the human activity is known to have quickly responded to this pandemics. Are there any other geophysical monitoring method of spread and human reactions?

(6) If you or your colleague have been infected, what was the consequence to your science and science colleague

(7) What will be the optimum method to have the highest science output during corona pandemic?

GM2.11 EDI

Recent advances in image collection, e.g. using unmanned 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 landscape scale.

For both historic and contemporary scenarios, the rise of techniques with ‘structure from motion’ (SfM) processing has democratized data access 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 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) modelling technologies, iv) data processing tools, for instance, using machine learning approaches.

GI2 – Data networks and analysis

GI2.1

Non-destructive testing (NDT) methods have been increasingly employed in a wide range of engineering and geosciences applications and their stand-alone use has been greatly investigated to date. New theoretical developments, technological advances as well as 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 different 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.

Within this framework, this Session primarily aims at disseminating contributions from state-of-the-art NDT methods and 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;
- assessment and monitoring methods for material and site investigations;
- 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).

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 relation 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);
(e) Forestry;
(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.

GI2.3 EDI

The interactions between geo-environmental and anthropic processes are increasing due to the ever-growing population and its related side effects (e.g., urban sprawl, land degradation, natural resource and energy consumption, etc.). Natural hazards, land degradation and environmental pollution are three of the possible “interactions” between geosphere and anthroposphere. In this context, spatial and spatiotemporal data are of crucial importance for the identification, analysis and modelling of the processes of interest in Earth and Soil Sciences. The information content of such geo-environmental data requires advanced mathematical, statistical and geomorphometric methodologies in order to be fully exploited.

The session aims to explore the challenges and potentialities of quantitative spatial data analysis and modelling in the context of Earth and Soil Sciences, with a special focus on geo-environmental challenges. Studies implementing intuitive and applied mathematical/numerical approaches and highlighting their key potentialities and limitations are particularly sought after. A special attention is paid to spatial uncertainty evaluation and its possible reduction, and to alternative techniques of representation of spatial data (e.g., visualization, sonification, haptic devices, etc.).

GI2.4

Climate study related experiments and observational stations are getting bigger and number of sensors and instruments involved is growing very fast. Experiments like SPRUCE, NGEE-Arctic, NEON have to deal with hundreds of sensors and instruments. The most effective way to manage such large installations is to incorporate all equipment in to a network. At this session we would like people to share their experience in establishing, maintaining, and managing a fixed environmental sensor networks on or near surface measurements (it does not cover remotely sensed data - satellite imagery, aerial photography, etc.). This session is open for all works about an existing system, planning a completely new network, upgrading an existing system, improving streaming data management, and archiving data.

ESSI1.2

Source of most progress in artificial intelligence (AI) and machine learning (ML) can be traced back to data. Data, specifically, large-scale and openly-accessible training data are critical in adoption and acceleration of ML. While there are successful applications of ML in Earth science, the wider adoption of ML has been limited. Access to high-quality labeled training data is required to entice ML practitioners to tackle supervised learning problems in Earth science. However, creating labeled data that scales to support ML models is still a bottleneck and new strategies to increase the size and diversity of training datasets need to be explored. Additionally, enabling discovery and open sharing of existing training data and corresponding models to enable reproducibility of research and minimize duplication is a challenge.

This session seeks submissions from ML practitioners and data curators using different approaches to create labeled training data, catalog training data and models, and provide search, discovery and distribution of training data and models.

HS3.3 EDI

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) Application of covariance functions and copulas for the identification of spatio-temporal relationships
9) Geostatistical characterization of uncertainties and error propagation
10) Bayesian geostatistical analysis and hierarchical modelling

NH9.4 EDI

Availability of data and information is crucial to be able to take correct decisions at all levels in many sectors - including geosciences and natural hazards - and as a consequence big data have become fundamental. The new challenges coming from data complexity and the demands for faster information management, elaboration and extraction call for a paradigm shift in the way data is acquired, stored, processed and analysed. The solution for the challenges lies in the methods and in the technology, platform and software solutions of big data which are advancing rapidly. Especially the geospatial part of big data solution is a technology which is much newer and constantly in progress.
Natural hazards analysis and managements can largely befit from the use of big data methods and tools. In fact, it is common to handle large heterogenous datasets including remote sensing data (from different platforms – from UAV to satellites), data coming from environmental and/or physical models of the considered phenomena, socio economic information, data coming from citizen science initiatives and more.
The aim of this session is to bring together experiences coming from studies related to natural hazards making use of:
- Big data methods, including e.g. all different types of algorithms classified as machine/deep learning
- Big data tools useful for the analysis and storage of data such as distributed or cloud computing and/or storage.
The session also welcome presentation of innovative ways of presenting and communicating geospatial big data analysis’ results or integrating citizen science initiatives.
The session is organized in cooperation with NhET, Natural hazard Early Career Scientists Team

GMPV1.4 EDI

Newly developed geoscientific equipment and techniques in the past decades are helping produce geoscience data with increasing velocity, volume and variety, and to answer compelling scientific questions with these data that were previously difficult or impossible to address. Building and maintaining data resources is an important contribution to science and is gradually gaining more recognition as the number of data journals and publication platforms increase. Likewise, tools and methods are essential for geoscientists to build data resources, and extract information for large-scale, multidimensional data analysis to answer complex, sophisticated, and, in many cases, multi-disciplinary questions.
This session serves as a platform to present the data resources, their creation methods, and consequent data analysis techniques for improving and enabling scientific explorations. We welcome presentations on topics including but not limited to:
1. Geochemical, mineralogical, petrological, volcanological, and interdisciplinary data resources;
2. Their creation methods, such as data rescue, mining, and crowdsourcing, etc.;
3. Machine learning, deep learning, statistics, and geo-modeling for exploring scientific questions;

ESSI3.7 EDI

Earth science research has become increasingly collaborative through shared code and shared platforms. Researchers work together on data, software and algorithms to answer cutting-edge research questions. Teams also share these data and software with other collaborators to refine and improve these products. As data volumes continue to grow, researchers will need new platforms to both enable analysis at scale and to support the sharing of data and software.

Software is critical to the success of science. Creating and using Free and Open Source Software (FOSS) fosters contributions from the scientific community, creates a peer-reviewed and consensus-oriented environment, and promotes the sustainability of science infrastructures.

This session will look at how Free and Open Source Software (FOSS) and cloud-based architecture solutions support information sharing, scientific collaboration, scientific reproducibility and solutions that enable large-scale data analytics.

Research data are of critical importance to modern research and decision-makers. Regardless of their disciplinaries, researchers collect their observations and measurements (i.e., research data) in databases with different structures. The history of open-access can be traced back to the end of the 20th century when the university librarians around the world faced a problem known as the “serials crisis”. Before 2003, the term “open-access” was related only to free access to peer-reviewed literature (e.g., Budapest Open Access Initiative, 2002). In 2003 and during the “Berlin Declaration on Open Access to Knowledge in the Sciences and Humanities”, the definition was considered to have a wider scope that includes raw research data, metadata, source materials, and scholarly multimedia material. Increasingly, access to research data has become a core issue in the advance of science. With the advanced technology in digitalization and cloud storage, the scientific society had moved forward to reach an important milestone in the support of open research data.
The current session welcomes abstracts dealing with and presenting issues related to policies, technology, challenges, and future prospecting of open-access research data. Existing research data and data repositories cover different geographic areas are welcomed to be presented. As data collected from the Polar Regions are of critical importance to monitoring the changing in the Earth’s environment, we particularly welcome abstracts presenting research data or repositories with a focus on Polar Regions.

ESSI2.6

Earth Sciences depend on detailed multi-variate measurements and investigations to understand the physical, geological, chemical, biogeochemical and biological processes of the Earth. Making accurate prognoses and providing solutions for current questions related to climate change, water, energy and food security are important requests towards the Earth Science community worldwide. In addition to these society-driven questions, Earth Sciences are still strongly driven by the eagerness of individuals to understand processes, interrelations and tele-connections within and between small sub-systems and the Earth System as a whole. Understand and predict temporal and spatial changes in the above mentioned Micro- to Earth spanning scales is the key to understand Earth ecosystems; we need to utilize high resolution data across all scales in an integrative/holistic approach. Using Big Data, which are often distributed and particularly very in-homogenous, has become standard practice in Earth Sciences and digitalization in conjunction with Data Science promises new discoveries.
The understanding of the Earth System as a whole and its sub-systems depends on our ability to integrate data from different disciplines, between earth compartments, and across interfaces. The need to advance Data Science capabilities and to enable earth scientists to follow best possible workflows, apply methods, and use computerized tools properly and in an accessible way has been identified worldwide as an important next step for advancing scientific understanding. This is particularly necessary to access knowledge contained in already acquired data, but which due to the limitations of data integration and joint exploration possibilities currently remains invisible. This session aims to bring together researchers from Data and Earth Sciences working on, but not limited to,
• SMART monitoring designs by dealing with advancing monitoring strategies to e.g. detect observational gaps and refine sensor layouts to allow better and statistically robust extrapolation
• Data management and stewardship solutions compliant with FAIR principles, including the development and application of real-time capable data management and processing chains
• Data exploration frameworks providing qualified data from different sources and tailoring available computational and visual methods to explore and analyse multi-parameter data generated through monitoring efforts/ model simulations

Most of the processes studied by geoscientists are characterized by variations in both space and time. These spatio-temporal phenomena have been traditionally investigated using linear statistical approaches, as in the case of physically-based models and geostatistical models. Additionally, the rising attention toward machine learning, as well as the rapid growth of computational resources, opens new horizons in understanding, modeling, and forecasting complex spatio-temporal systems through the use of stochastics non-linear models.

This session aims at exploring the new challenges and opportunities opened by the spread of data-driven statistical learning approaches in Earth and Soil Sciences. We invite cutting-edge contributions related to methods of spatio-temporal geostatistics or data mining on topics that include, but are not limited to:
- advances in spatio-temporal modeling using geostatistics and machine learning;
- uncertainty quantification and representation;
- innovative techniques of knowledge extraction based on clustering, pattern recognition and, more generally, data mining.

The main applications will be closely related to the research in environmental sciences and quantitative geography. A non-complete list of possible applications includes:
- natural and anthropogenic hazards (e.g. floods; landslides; earthquakes; wildfires; soil, water, and air pollution);
- interaction between geosphere and anthroposphere (e.g. land degradation; urban sprawl);
- socio-economic sciences, characterized by the spatial and temporal dimension of the data (e.g. census data; transport; commuter traffic).

ESSI3.9 EDI

Significant investments are made globally in laboratory analytical research in the Earth and space sciences to extract new scientific insights from Earth and planetary materials. Expensive laboratory infrastructure and advanced instrumentation generates data at an ever increasing level of precision, resolution, and volume. Any data generated at any scale needs to be efficiently managed and losslessly transferred from instruments in “Private” domains to a “Collaboration” domains, where researchers can analyze and share these data as well as the analytical tools. Ultimately, the data need to be transferred to the “Public” domain, complete with all relevant information about the analytical process and uncertainty, and cross-references to originating samples and publications. 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.

This session seeks contributions about new developments to achieve FAIR, scalable and sustainable access to analytical data from any laboratory instrument and domain at any scale (from an individual instrument in a geochemical lab to data measured with synchrotrons), and any stage from the initial collection of the sample through to the publication of the final data, including the use of persistent identifiers to uniquely identify samples, instruments, researchers, grants, data, etc. Papers are welcome on systems that transfer data/metadata directly from instruments to “collaborative storage areas” that facilitate sharing and processing of geochemical data, as well as systems that transfer data used in publications to relevant repositories that ensure long term persistence of data and enhanced reproducibility of geochemical research.

Cartography and mapping are at this time the only means to conduct basic geoscientific studies (on planetary surfaces). The field of Planetary Cartography and Mapping has been stepping out of its niche existence in the last 15 years due to the availability of an unprecedented amount of new data from various planetary exploration missions from different countries and the advent of internet technology that allows to manage, process, distribute, analyze, and collaborate efficiently. Geospatial information system technology plays a pivotal role in this process and essentially all planetary surface science research in this field benefits from this technology and frequent new developments.
With the availability of data and connection, however, comes the challenge of organizing and structuring available data and research, such as maps and newly derived and refined (base) data that is about to enter its new research life cycle.
This session welcomes presentations covering planetary data and its development into cartographic products and maps. This covers aspects of data archival, dissemination, structuring, analyzing, filtering, visualizing, collaboration, and map compilation but is not limited to these topics.
It should also be emphasized that the exchange of knowledge and experiences from the Earth Sciences would be highly beneficial for the Planetary Data Sciences.

ESSI1.19

Space-based measurements of the Earth System, including its atmosphere, oceans, land surface, cryosphere, biosphere, and interior, require extensive prelaunch and post launch calibration and validation activities to ensure scientific accuracy and fitness for purpose throughout the 
lifetime of satellite missions. This requirement stems from the need to demonstrate unambiguously that the space-based measurements, typically based on engineering measurements by the detectors (e.g. photons), are sensitive to and can be used to retrieve reliably the geophysical and/or biogeochemical parameters of interest at locations across the Earth.
Most geophysical parameters vary in time and space, and the retrieval algorithms used must be accurate under the full range of conditions. Calibration and validation over the lifetime of missions assure that any long-term variation in observation can be unambiguously tied to the evolution of the Earth system. Such activities are also critical in ensuring that measurements from different satellites can be inter-compared and used seamlessly to create long-term multi-instrument/multi-platform data sets, which serve as the basis for large-scale international science investigations into topics with high societal or environmental importance. Examples of such investigations include the ice mass balance of Greenland, monitoring the evolution of sea ice and snow cover in the Arctic, assessing sinks and sources of methane in the Arctic and improving our knowledge of the terrestrial carbon cycle through multi-sensor forest biomass mapping. This session seeks presentations on the use of surface-based, airborne, and/or space-based observations to prepare and calibrate/validate space-based satellite missions measuring our Earth system. A particular but not exclusive focus will be on activities carried out jointly by NASA and ESA as part of their Joint Program Planning Group Subgroup on calibration and validation and field activities.

The use of Remotely Piloted Aircraft Systems (also called UAS) for natural hazard characterization and hazard assessment has sharply increased in the last years. Nowadays, the massive diffusion of mini- and micro-RPAS is becoming a valuable alternative to the traditional monitoring and surveying techniques, opening novel and exciting viewpoints. The advantages of the use of RPAS are particularly crucial in areas characterized by hazardous natural processes, where the acquisition of high resolution remotely sensed data could be a powerful instrument to quickly assess the damages and plan effective rescues without any risk for operators.
In general, the primary goal of these systems is the collection of different data (e.g., images, LiDAR point clouds, gas or radioactivity concentrations) and the delivery of various products (e.g., 3D models, hazard maps, high-resolution orthoimages).
The use of RPAS has promising perspectives not only for natural hazards, but also in other fields of geosciences, to support a high-resolution geological or geomorphological mapping, or to study the evolution of active processes. The high repeatability of RPAS flights and their limited costs allows the multi-temporal analysis of a studied area. However, methodologies, best practices, advantages and limitations of this kind of applications are yet unclear and/or poorly shared by the scientific community.
This session aims at exploring the open research issues and possible applications of RPAS in particular for natural hazard but also for geosciences in general, collecting experiences, case studies, and results, as well as defining methodologies and best practices for their practical use. The session will concern the contributions aiming at i) introducing new methods for using RPAS in natural hazard scenarios, including autonomous flights ii) describing the development of new onboard sensors and fusion methodologies for the acquisition data with RPAS, iii) reporting new data processing methods, e.g. based on machine learning, for image or point cloud segmentation and classification, and iv) presenting original case studies that can be considered an excellent example for the scientific community.

In 2020, the Japanese Aerospace Exploration Agency (JAXA) and the European Space Agency (ESA) signed an agreement on the “Cooperation for the Use of Synthetic Aperture Radar Satellites in Earth Science and Applications”. The cooperation focuses on the joint analysis of L-band data acquired by JAXA’s ALOS-2/PALSAR-2 satellite together with ESA’s Sentinel-1 C-band satellite data for various applications. Research areas include polar and ocean monitoring, snow water equivalent retrieval, forest and wetland monitoring, surface soil moisture and agriculture monitoring, as well as the monitoring of geohazards and urban areas.

The key objective of the JAXA-ESA cooperation is to develop a better understanding of the benefits of combining L-band and C-band data over various areas and for the different thematic applications. A comparison with ground-based campaign data is envisaged to validate the results. The research projects will provide important insights for the development of future (L-band) SAR satellite missions, such as JAXA’s ALOS-4 satellite and the High Priority Candidate Mission (HPCM) ROSE-L currently in development at ESA, as well as synergies with existing and future spaceborne C-band SAR missions including Sentinel-1 and Sentinel-1 Next Generation.

This jointly chaired session shall give the involved scientists the opportunity to present ongoing research and results and foster the collaboration and exchange between European, Japanese and international participants.

GI4 – Atmosphere and ocean monitoring

GI4.1 EDI

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 monitor research: 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

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.

Global plastic production has increased exponentially since the fifties, with 359 million metric tons manufactured in 2018 alone. Nearly 20% of this production took place within Europe, where at least half of discarded plastics collected for ‘recycling’ were instead exported to China and SE Asia. Every year, an increasing proportion of these plastics (in the order of millions of tons) enter and accumulate in our waterways and oceans. In riverine and marine systems, the presence of micro to macroplastic debris has generated a growing and persistent threat to the environment and ecosystems, as well as an urgent and multi-dimensional challenge for our society.

Methods for resource-efficient and large-scale detection and monitoring of plastic litter are still relatively new. However, in the last few years, they have blossomed across technologies and environments - from mounted cameras to drones to satellites, and from lakes and rivers to coastal waters and open oceans. These new technologies can be crucial to fill in the gaps between limited in situ observations and global models, allowing coverage across fine as well as large spatial scales, and over long time periods. We invite abstracts describing the use of cameras, drones, satellites and other remote sensing techniques to observe and monitor riverine and marine plastics. We also welcome work describing or demonstrating new approaches, methods and algorithms to improve the use of cameras and sensors for plastic detection on (and in) water.

Water is our planet’s most vital resource, and the primary agent in some of the biggest hazards facing society and nature. The twin pressures of population growth and a rapidly changing global climate act as multipliers of water’s value and of water-related hazards.

River streamflow is one of the most crucial hydrological variables for ecology, for people and industry, for flood risk management and for understanding long term changes to the hydrological regime. However, despite significant efforts, long-term, spatially dense monitoring networks remain scarce, and even the best monitoring networks can fail to perform when faced with extreme conditions, and lack the precision and spatial coverage to fully represent crucial aspects of the hydrological cycle.

Happily, a number of new technologies and techniques are emerging which show great potential to meet these challenges. In this context, this session focuses on:
1) Innovative methodologies for measuring/modelling/estimating river stream flows;
2) Real-time acquisition of hydrological variables;
3) Remote sensing for hydrological & morphological monitoring;
4) Measuring extreme conditions associated with a changing climate;
5) Measurement of sudden-onset extreme flows associated with catastrophic events;
6) Strategies to quantify and describe hydro-morphological evolution of rivers;
7) New methods to cope with data-scarce environments;
8) Inter-comparison of innovative & classical models and approaches;
9) Evolution and refinement of existing methods;
10) Guidelines and standards for hydro-morphological streamflow monitoring;
11) Quantification of uncertainties;
12) Development of expert networks to advance methods.

Contributions are welcome with an emphasis on innovation, efficiency, operator safety, and meeting the growing challenges associated with the changing climate, and with natural and anthropogenically driven disasters such as dam failures and flash floods.

Additionally, presentations will be welcomed which explore options for greater collaboration in advancing riverflow methods and which link innovative research to operational monitoring.

This session is sponsored by the COST Action CA16219, Harmonisation of UAS techniques for agricultural and natural ecosystems monitoring (HARMONIOUS).

Evapotranspiration (ET), the key component of water and energy balances, has myriad challenges to measure it precisely. In the last two decades, innovative approaches for remote sensing (RS) based measurements of ET has allowed for its measurement in a range of climates on most continents for different green covers. Remotely-sensed ET methods have been proved to be reliable, affordable and applicable to a broad range of scales from plot/field to regional to global in different landscapes including agricultural, forested, riparian zones and urban green spaces.

We invite researchers to contribute abstracts to share their advances and challenges in the development, application, validation, calibration and accuracy assessment of landscape ET through remote sensing platforms. We welcome studies that estimate ET using both prognostic and diagnostic approaches from process-based models that rely on the integration of gridded precipitation and soil-vegetation dynamics to a more direct estimation of ET using remote sensing-based data streams. The scope of the session will include: (1) advances in remote sensing-based ET estimation, (2) applications for a range of land covers and spatiotemporal scales, and (3) accuracy enhancement.

Geophysical and in-situ measurements of the cryosphere offer important baseline datasets, as well as validation for modelling and remote sensing products. In this session we welcome contributions related to a wide spectrum of methods, including, but not limited to radioglaciology, active and passive seismology, acoustic sounding, Global Navigation Satellite System (GNSS) reflectometry or time delay techniques, cosmic ray neutron sensing, remotely operated vehicle (ROV) or drone applications, geoelectrics, nuclear magnetic resonance (NMR) and methods in radiative transfer (i.e. infrared photography, thermal sounding...).
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.

This session is offered as a hybrid PICO session, meaning it will allow physical and remote contributions - which we hope will increase the accessibility of this session to a wider range of presenters. The PICO format has proved to be an engaging presentation format for this session in previous years. The session begins with each presenter giving a “quick fire” overview of their research orally, followed by time to discuss and further present their research using interactive screens. This results in rich scientific feedback and is an effective tool for communicating science with high visibility.

Terrestrial radar interferometry (TRI) appeared in the late 90s and since then it proved to be a valuable and versatile tool in many applications in geosciences. It has been adopted to survey landslides, glaciers and rock-glaciers, open pits, volcanoes, infrastructures, buildings and rock cliffs. Its main advantages are i) high acquisition rate, ii) spatially distributed deformation maps several km2 wide, iii) continuous acquisition during day and night and in the presence of adverse weather, iv) sub-millimetre sensitivity and v) the possibility to remotely measure the studied process. These features make TRI useful for scientific investigation of natural processes and also for warning purposes.
However, several issues affect this technology and must be investigated to exploit the TRI potentiality fully. The atmospheric phase screen still remains an unresolved problem that strongly limits the use of TRI in a harsh environment. Speckling, temporal and spatial phase wrapping represent further examples of issues in the data processing chain.
Traditionally, TRI measurements are conducted in the Ku band and VV polarisation. Only in recent years, the scientific community began to analyse different frequency bands and polarisation configurations, which can help in overcoming the problems mentioned above. Moreover, besides deformation measurements, terrestrial radars might be used for other purposes, such as radar imaging, target classification or change detection.
This session aims at exploring the open issues in TRI and the possible approaches that can extend the use of TRI in original applications. In particular, we invite contributions that treat i) analysis of the atmospheric phase screen and possible methods to mitigate it, ii) data integration with different sensors, iii) adoption of different frequency bands or polarisations, iv) original case studies that can represent excellent examples of TRI applications.

An unmanned aerial vehicle (UAV), commonly known as a drone, is an aircraft without a human pilot aboard. Originating mostly from military applications, their use is rapidly expanding to commercial, recreational, agricultural, and scientific applications. Unlike manned aircraft, UAVs were initially used for missions too "dull, dirty, or dangerous" for humans. Nowadays however, many modern scientific experiments have begun to use UAVs as a tool to collect different types of data. Their flexibility and relatively simple usability now allow scientist to accomplish tasks that previously required expensive equipment like piloted aircrafts, gas, or hot air balloons. Even the industry has begun to adapt and offer extensive options in UAV characteristics and capabilities. At this session, we would like people to share their experience in using UAVs for scientific research. We are interested to hear about specific scientific tasks accomplished or attempted, types of UAVs used, and instruments deployed.

Research and innovation in exploration and mining of raw materials is increasingly focused on the prospect of developing completely new methods and technologies to find and exploit new mineral deposits within Europe. Amongst these technologies, robotisation and miniaturization of exploration/production platforms (robotic autonomous explorers & miners) allow to reconsider “non-economical” deposits (abandoned, small, ultra-depth), extract them in a socially and environmentally responsible way, and produce useful metallurgical products which can be used further-on for manufacturing.

This session targets current research helping operation of an autonomous or semi-autonomous underground platform in mineral exploration or extraction. This is an extremely challenging task for which potential solutions will most likely be proposed from close collaboration of robotic engineers, mining engineers, mineralogists, geochemists, geophysicists and (structural) geologists. The challenges are very diverse and comprise for example locomotion techniques in water or slurries, localization and mapping in relationship to an orebody, automated ore following and extraction planning, optimization of extraction tools, and real-time selective mineralogy.

Tectonically and volcanically active areas are subject to faulting, fracturing, volcanic eruptions, caldera or flank collapse, and magmatic intrusions, such as dyking. These events trigger typical geomorphological features and geomorphological changes that researchers can study in the field and remotely. Satellite data using optical or thermal sensors, and ship acoustics datasets, provide first order information about faulting and volcanic activity, however, there is a resolution gap below the meter-scale, critical to detect and to analyse small structures over broad areas and to better assess how faults, magma intrusions and collapses nucleate and evolve. Moreover, during large metrical ground deformations (earthquakes, dyke intrusions, collapses), the near-field area where satellite radar signal (InSAR) becomes incoherent remains poorly studied, likewise happens in deep sea environments using vessel-based acoustics techniques. In addition, classical field surveys and data collection are, very often, not feasible due to difficult logistic conditions and/or inaccessible areas. Therefore, there is a need to collect higher resolution data to better understand geomorphologic, faulting and volcanic processes at scales from cm to a few meters, that complement classical field studies and remote sensing data.
Structure-from-Motion (SfM) photogrammetry techniques have been applied using imagery acquired from field, aerial and underwater survey, using Unmanned Aerial Vehicles (UAVs, i.e. drones), Remotely Operated Vehicles (ROVs), Autonomous Underwater Vehicles (AUVs), balloons, airplanes and helicopters, as well as cameras and mobile phones. This technique produces digital surface models (DSM), ortho-mosaic imagery, dense point clouds and 3-D models, creating a high-resolution environment reconstruction for local outcrops or broader areas.
The session will focus on the application of SfM for research in the field of structural geology, active tectonics, volcano-tectonics, and geomorphology, with particular regard to tectonically and volcanically active areas. The session covers the following topics: i) case studies where the SfM has been employed; ii) SfM methods, 3-D reconstruction and post-processing analysis; iii) integration and comparison of SfM-derived, field and broad-scale data (such as satellites and acoustics techniques); iv) new tools and methods for data analysis on SfM-derived models; and vi) future works and applications of SfM techniques.

Seismic techniques are becoming widely used to detect and quantitatively characterise a wide variety of natural processes occurring at the Earth’s surface. These processes include mass movements such as landslides, rock falls, debris flows and lahars; glacial phenomena such as icequakes, glacier calving/serac falls, glacier melt and supra- to sub-glacial hydrology; snow avalanches; water storage and water dynamics phenomena such as water table changes, river flow turbulence and fluvial sediment transport. Where other methods often provide limited spatial and temporal coverage, seismic observations allow recovering sequences of events with high temporal resolution and over large areas. These observational capabilities allow establishing connections with meteorological drivers, and give unprecedented insights on the underlying physics of the various Earth’s surface processes as well as on their interactions (chains of events). These capabilities are also of first interest for real time hazards monitoring and early warning purposes. In particular, seismic monitoring techniques can provide relevant information on the dynamics of flows and unstable slopes, and thus allow for the identification of precursory patterns of hazardous events and timely warning.

This session aims at bringing together scientists who use seismic methods to study Earth surface dynamics. We invite contributions from the field of geomorphology, cryospheric sciences, seismology, natural hazards, volcanology, soil system sciences and hydrology. Theoretical, field based and experimental approaches are highly welcome.

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 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.

An additional contribution to the environmental radioactivity comes from the fallout of artificial radionuclides (e.g. Cs-137, Cs-134) from nuclear and radiation accidents and incidents.
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:

- volcanic monitoring and surveillance;
- identification of faults and tectonic structures;
- mineral exploration;
- coastal and marine monitoring;
- soil erosion processes;
- Naturally Occurring Radioactive Materials (NORMs) and Taylor-made building materials;
- geostatistical methods for radioactivity mapping;
- atmospheric tracing, mixing and transport processes;
- Radon Eurocode and indoor air quality monitoring
- cosmic rays;
-fingerprinting approaches of natural waters (e.g. groundwater resources for mineral and drinking water)
- public health linked to the EU BSS and Euratom directives.

Contributions on novel methods and instrumentation for environmental radioactivity monitoring are particularly encouraged, including payloads for airborne measurements, drones and small satellites.

Environmental changes in terrestrial ecosystems and coastal areas across the Arctic can only be fully addressed by using remote sensing observations and modelling. However, due to the multiscale complexity of the landscape, to limitations related to illumination and atmospheric conditions, bridging the gap between field and satellite observations remains a major challenge. Contributions may include, but not limited to, recent advances in instrumentation and methodology for
validation and calibration of remote sensing products, applications of joint use of in situ and satellite records to tackle science questions, demonstrate the utility of UAV for bridging the scale gap, progress for standardization (protocols) or reviewing challenges.

We specifically welcome contributions within the framework of ​T-MOSAiC. T-MOSAiC is an IASC pan-Arctic, land-based program. The objective of T-MOSAiC is to coordinate activities that will both aid and benefit from MOSAiC (especially the modelling components) by extending the work to the lands surrounding the Arctic Ocean and to the northern communities who live on those lands.

The Remote Sensing Action Group of T-MOSAiC
(https://www.t-mosaic.com/remote.html) aims at shortening the path between field scientists and the remote sensing community, by increasing the availability of calibration and validation data at the circumpolar scale. The action group makes use of UAV and satellite data collected with different sensors and to improve the data and models that address issues such as: permafrost characteristics, thaw lake dynamics, coastal erosion, vegetation community dynamics and infrastructure.

Observations from aircraft, unmanned aerial vehicles/systems (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 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 UAVs.
Applications include atmospheric parameters, surface 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 cover large areas in the horizontal and vertical 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 UAV operators and the research community to present:
• an overview of the current status of environmental research with a focus on the use of airborne platforms
• recent observation campaigns and their outcomes
• multi-aircraft/balloon/UAV 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 observational research

Geomorphometry and geomorphological 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 has made available vast quantities of geospatial data for such morphometric analysis and mapping, with the 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”.

Soil is not only a vital source for vegetation, but also a hydrologic cycle zone in which numerous biological, physical and chemical interactions occur among the mineral material of the original and deformed rocks, soil life (micro-organisms, plants, animals), and climate (water, air, temperature) at different scales. These various processes and mechanisms, associated with soil formation and genesis, distinct soils very dynamic and highly complex, creating multi-scales of structure. Soil complexity can thus be observed at different physical levels (i.e.,pore and field scales), biological levels (i.e., oxidable organic matter availability, population distribution, etc.), interaction levels (i.e. mineral paths between compartments, etc.), or evolutionary levels (short-term variations on water availability, long term erosion, etc.).

In this session, we invite contributions related to the modelling and quantifying aspects, which improve our understanding of those systems and mechanisms linked with. In particular, we encourage studies applying integrated, cross-disciplinary approaches, whether based on either statistical/theoretical techniques –which allow scaling analysis– or fully formulated physical-biogeochemical models. The potential topics include, but are not limited to: statistical learning, data mining, time series analysis, network analysis, cellular automata, fractal/multifractals, wavelets, genetic algorithms, graph theory, effective-medium approximation, lattice-Boltzmann method, and percolation theory.
