Anthropogenic and Natural Emissions for Atmospheric Chemistry Global and Regional Modelling

Abstract:

As part of the European Copernicus Atmosphere Service (CAMS), datasets providing global and regional European emissions have been developed. These datasets consider anthropogenic and natural sources and can be used to drive atmospheric models which deliver air quality forecasts and analyses of atmospheric composition. Anthropogenic emissions are available for several atmospheric compounds for the 2000-2020 period at a 0.1x0.1 degree resolution at the global scale and for 2000-2017 at a 0.05x0.1 degree for the European continent. In addition, detailed emissions from ships based on automatic identification systems have been developed. New temporal profiles at different scales have also been developed. Different datasets providing natural emissions have been processed, such as the emissions of biogenic volatile organic compounds from vegetation, nitrogen compounds emissions from soils, emissions from the oceans and emissions from volcanoes. All the emissions developed in CAMS are available from the ECCAD (Emissions of atmospheric Compounds and Compilation of Ancillary Data: eccad.aeris-data.fr) database. The database includes also tools for visualization and download of the data and for an easy evaluation of the CAMS emissions dataset through comparisons with other datasets. We will detail the status of the development of each dataset in the presentation, and discuss comparisons with other available emissions.
