The project GAIA-CLIM

The aim of the Gap Analysis for Integrated Atmospheric ECV CLImate Monitoring (GAIA-CLIM) project is to improve our ability touse ground-based and sub-orbital observations to characterize satellite observations for a number of atmospheric EssentialClimate Variables (ECVs). The key outcomes will be a “Virtual Observatory” (VO) facility of co-locations and their uncertainties anda report on gaps in capabilities or understanding, which shall be used to inform subsequent Horizon 2020 activities.

In particular, Work Package 1 (WP1) of the GAIA-CLIM project is devoted to the geographical mapping of existing non-satellitemeasurement capabilities for a number of ECVs in the atmospheric, oceanic and terrestrial domains.The work carried out within WP1 has allowed to provide the users with an up-to-date geographical identification, at the Europeanand global scales, of current surface-based, balloon-based and oceanic (floats) observing capabilities on an ECV by ECV basis forseveral parameters which can be obtained using space-based observations from past, present and planned satellite missions.

Metadata collectionHaving alighted on a set of metadata schema to follow, a consistent collection of discovery metadata has been provided into acommon structure and will be made available to users through the GAIA-CLIM VO in 2018.Metadata can be interactively visualized through a 3D Graphical User Interface.The metadataset includes 54 plausible networks and 2 aircraft permanent infrastructures for EO Characterization in the context ofGAIA-CLIM currently operating on different spatial domains and measuring different ECVs using one or more measurementtechniques.Each classified network has in addition been assessed for suitability against metrological criteria to identify those with a level ofmaturity which enables closure on a comparison with satellite measurements.

Tool 3DThe metadata GUI is based on Cesium, a virtual globe freeware and open source written in Javascript. It allows users to apply different filters to the data displayed onthe globe, selecting data per ECV, network, measurementstype and level of maturity. Filtering is operated with a query to GeoServer web application through the WFS interface on a data layer configured on our DB Postgres withPostGIS extension; filters set on the GUI areexpressed using ECQL (Extended Common Query Language).

The GUI allows to visualize in real-time the current non-satellite observing capabilities along with the satellite platforms measuring the same ECVs. Satellite groundtrack and footprint of the instruments on board can be alsovisualized.

This work contributes to improve metadata and web map services and to facilitate users’ experience in the spatio-temporal analysis of Earth Observation data.
