The Emissions of atmospheric Compounds & Compilation of Ancillary Data (ECCAD) database provides a user-friendly access to surface emissions and ancillary data, i.e. data on land use, active fires, burned areas, population, etc. These data can be directly viewed or downloaded. ECCAD is the emissions database of the GEIA (Global Emissions InitiAtive) project and a sub-project of AERIS the French Data and Services Cluster for Atmosphere (CNES and CNRS, https://www.aeris-data.fr/). ECCAD distributes also the emissions dataset developed as part of the Copernicus Atmosphere Monitoring Service (https://atmosphere.copernicus.eu/)
The ECCAD database includes more than 100 datasets with a large diversity of sources, which provide global and regional surface emissions for a large set of chemical compounds, at several resolutions (0.25x025, 0,1x0,1, 1x1 degree etc) and several sectors. The database has currently more than 2500 users originating from more than 80 countries on 836 institutes. The project benefits from this large international community of users to expand the number of emission datasets made available.
ECCAD provides detailed metadata for each of the datasets, including information on references, how to cite the datasets when used, the methodology, and links to the original inventories. It can also provides DOIs. Several tools are provided for the visualization of the data, for computing global and regional totals and for an interactive spatial and temporal analysis. The data can be downloaded as interoperable NetCDF CF-compliant files, i.e. the data are compatible with many other client interfaces.
The ECCAD database and web interface are under constant development to enhance the user experience: better download granularity, new tools to improve the analysis and comparison of emissions and ancillary data. They include geographical masking, arithmetic expressions to combine different maps, new tools for temporal profiles analysis, and comparisons of data at different scales.
The presentation will provide information on all the datasets available within ECCAD, as well as examples of the analysis work that can be done online through the website: https://eccad.sedoo.fr
