ATMO-Insights: An Interoperable Platform for IAGOS, ACTRIS and ICOS Data

Integrating data from multiple atmospheric research infrastructures remains a significant challenge for Earth System Science. Each infrastructure typically maintains its own data formats, access protocols, and processing workflows, creating barriers for scientists seeking to conduct cross-cutting analyses. The ATMO-Insights service addresses this challenge by providing unified access to long-term observational data from three major European research infrastructures: ACTRIS (Aerosol, Clouds and Trace Gases Research Infrastructure), IAGOS (In-service Aircraft for a Global Observing System), and ICOS (Integrated Carbon Observation System).

Developed within the H2020 ATMO-ACCESS project, the ATMO-Insights service offers a web-based graphical interface for interactive exploration. The platform provides seamless access to quality-controlled Level 2 data from ACTRIS and ICOS ground-based stations, as well as Level 3 aggregated vertical profiles and regional data products from IAGOS aircraft measurements. All datasets are published under Creative Commons Attribution 4.0 International license (CC BY 4.0), ensuring FAIR data principles.

The service implements a comprehensive workflow including dataset discovery through Essential Climate Variables (ECVs), interactive data filtering, and a suite of statistical analysis methods. Users can perform exploratory analysis (means, percentiles, moving averages), trend estimation (linear regression, Mann-Kendall test, Theil-Sen slope), and multivariate analysis (2D/3D scatter plots, linear regression) with customizable parameters. Results are visualized through interactive annotated plots.

The platform enables researchers to combine atmospheric observations across different measurement platforms and geographical locations. This service demonstrates how research infrastructure interoperability can be achieved through unified data access layers, common processing workflows, and harmonized analysis tools, facilitating cross-disciplinary scientific applications in climate and air quality research.
