TNO-CO2_CIRCE projections (2018-2050)

To provide modellers with an emission dataset that is indicative of the possible future emissions in Europe under two different policy pathways we use two global emission scenarios developed by the EDGAR team in the CIRCE project (Doering et al., 2010).  The selected scenarios are a business-as-usual (BAU) and a climate change (CC) scenario. The two CIRCE scenarios contain detailed information about the development of individual source sector categories. By coupling these scenarios to TNO-CAMS gridded CO2 data, the emission changes in each grid-cell and for each region can be estimated in a spatially explicit manner. The projections start from the latest historic year in the the TNO_CAMS-CO2 data set, being 2014. The emission data can be used for e.g. for sensitivity tests, for example when designing a possible future observational system. The years covered in the data set are 2018, 2020, 2023, 2028, 2030, 2033, 2050. This selection has been made to include the 5-year time steps fro the global stocktake in the Paris Agreement. 

The emission grid consists of UNECE-Europe in WGS84 projection (lon-lat) with a spatial resolution of 1/8 x 1/16 degrees (lon x lat). The lower left of the grid is at lon = -60, lat = 30 and the upper right is at lon = 60, lat = 72.

The netcdf grid files (.nc)  contain annual total emissions per grid cell for the years 2018, 2020, 2023, 2028, 2030, 2033, 2050. A separate file has been prepared for each year and each scenario (BAU or CC). The unit in the .nc files is kg/gridcell/yr

Sectoral breakdown  uses the SNAP classification. Compared to the default SNAP1 sectors (1 to 10), the following change was made:

• SNAP 3 and SNAP 4 are grouped as SNAP 34

• SNAP 7 is split in SNAP 71 to 75
