This document reports on progress and current status within WP2 regarding the “Emissions and natural fluxes Dataset” developed and needed in CHE WP2. The scope of WP2 “Coordinating efforts on library of simulations for emissions and atmospheric transport” is to generate a library of realistic CO₂ simulations for present-day and future emission scenarios, from the global to the regional and point-source scale. Combining these simulations outputs with satellite orbit simulations will result in a collection of synthetic satellite observations.

To be able to do the necessary (test) simulations, model teams in CHE WP2, WP3 and WP4 need emission datasets as input. This deliverable report briefly introduces the emissions data for the CHE project at 3 different scales (global, regional and local) for anthropogenic emissions of CO₂ and co-emitted species as well as biogenic fluxes of CO₂ at local to regional scale. More specifically, the partner MPG has provided the first biogenic fluxes simulation outputs performed with the VPRM model (chapter 3). The partner JRC has produced the global gridded anthropogenic CO₂ emissions (EDGAR) needed as input to WPs 2 and 3 for the nature run for year 2015 and for a climate change scenario up to year 2030 (chapter 4). The partner TNO has produced a regional (European) gridded anthropogenic emission inventory for 2015 including CO₂ and co-emitted species (chapter 5). The partner EMPA has processed a detailed emission inventory for the city of Berlin (chapter 6) into a longitude-latitude grid used for the CHE project which will be nested into a ~1 km x1 km version of a selected domain of the TNO regional inventory.

The tasks within WP2 have progressed significantly but small delays to the plan are due to some further harmonization processes of the model setups needed for the final runs. Additionally, a coarser resolution product for the biogenic fluxes is provided due to data size issues.
