TNO-CAMS European CO2 emissions 2000-2014 v1

<p><strong>Introduction</strong></p> <p>This TNO_CAMS_CO2 emission dataset was prepared by TNO as a contribution to the H2020 project MACC-III and the subsequent Copernicus Atmospheric Monitoring Service. This model-ready historic emission inventory at high spatial resolution (~7x7 km) for UNECE-Europe for 15 consecutive years (2000–2014) providing CO₂ from fossil fuels and CO₂ from biofuels is intended to support modelling and sub-national scale identification of emissions. Where available and considered fit for purpose, we have used CO₂ estimates as reported by the Parties to UNFCCC. The data have been supplemented by other estimates, most notable from the IIASA GAINS model and the JRC EDGAR database to create a complete coverage.  The approach to the spatial distribution of the dataset is similar to the TNO-MACC emission dataset for air pollutants ( see Kuenen et al., ACP, 2014).</p> <p>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.</p> <p>The grid files TXT (.csv)  & netcdf (.nc) both contain annual total emissions per grid cell for the year 2000-2014. A separate file has been prepared for each year. </p> <p>The unit in the .csv files is Mg/gridcell/yr</p> <p>The unit in the .nc files is kg/gridcell/yr</p> <p>Sectoral breakdown  uses the SNAP classification. Compared to the default SNAP1 sectors (1 to 10), a couple of refinements have been made to the sectors:</p> <ul> <li> <p>SNAP 3 and SNAP 4 are grouped as SNAP 34</p> </li> <li> <p>SNAP 7 is split in SNAP 71 to 75</p> </li> </ul> <p>The dataset is described in </p> <p>Denier van der Gon, H.A.C., J.J.P.

TNO-CO2_CIRCE projections (2018-2050)

<p>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. </p> <p>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).
