CAMS2_61_bis Global and European emission inventories

Research Project, 2025 – 2028

ECMWF, as the Entrusted Entity for the Copernicus Atmosphere Monitoring Service (CAMS), invites tenders for providing gridded distributions of anthropogenic (global and Europe) and natural emissions (global only) for reactive gases, aerosols and greenhouse gases in direct support of CAMS production chains, with target resolutions of 25 km (natural emissions), 10 km (global) and 5 km (Europe).

The emissions include aerosol, reactive gases, and greenhouse gases. They must also be stratified into headline activity sectors, where relevant. The emission data sets cover the requirements of both the CAMS reanalyses products and the CAMS near-real-time products, as further specified in the sections below. Besides the yearly totals, the project delivers monthly, weekly and diurnal temporal profiles, so that variations can be accounted for in the CAMS systems. The project also provides activity-based emission estimates of CO2 and related species as close to real-time as possible. Furthermore, the provision of an up-to-date global point source emission database shall be part of the activities. Improving the representation of the temporal variations of emissions and investigating modelling methodologies to calculate certain emissions as a function of meteorological parameters (including forecasted ones) or of other proxies will be in scope of the developmental aspects of the work as are further development activities to improve the emission data sets.
