EDGARv4.2 Emission Maps

The global emissions in the EDGAR v4.2 are calculated for each compound on an annual basis for each sector using: the country-specific activity data (AD), the mix of technologies (TECH), the abatement percentage (EoP), and the country-specific emission factor (EF). These parameters are included in the calculations based on evaluation of scientific literature, inventory guidance, inventory reports, industry reports, dataset documentation or when data was found not available or incomplete own parameter calculations have been made. Data sources (e.g.): 1. AD from IEA, USGS, FAO, GFED; 2. TECH and EoP from UCI Platts Power Plant DB, EURO class vehicles; 3. EFs from IPCC 2006 and 1996, EMEP/EEA 2009 guidebooks, scientific literature etc. Emissions by country are allocated on a spatial grid, using proxy data, to provide gridded emissions dataset for atmospheric modeling. Proxy data (e.g.): 1. For diffusive emission sources - urban and rural population, road network, animal density, land use, inland waterways, and aviation and international shipping trajectories; 2. For point sources - maps with individual plant and industrial activity locations, such as power plants, iron and steel plants, cement plants, but also location of coal mines and oil and gas production sites.Emissions are calculated for the following substances: 1.Direct greenhouse gases:Carbon Dioxide (CO2), Methane (CH4), Nitrous Oxide (N2O), Hydrofluorocarbons (HFC-23, 32, 125, 134a, 143a, 152a, 227ea, 236fa, 245fa, 365mfc, 43-10-mee), Perfluorocarbons (PFCs: CF4, C2F6, C3F8, c-C4F8, C4F10, C5F12, C6F14, C7F16), Sulfur Hexafluoride (SF6) and Nitrogen Trifluoride (NF3); 2.Ozone precursor gases: Carbon Monoxide (CO), Nitrogen Oxides (NOx), Non-Methane Volatile Organic Compounds (NMVOC) and Methane (CH4); 3.Acidifying gases: Ammonia (NH3), Nitrogen oxides (NOx) and Sulfur Dioxide (SO2).; 4.Stratospheric Ozone Depleting Substances: Hydrochlorofluorocarbons (HCFC-141b, 142b). These emissions are presented as emissions on the grid using Geographical Coordinate System (lon, lat) in the following formats: txt, netcdf for 0.1 degree, netcdf for 0.5 degree and 1 degree global gridmaps. Annual gridded emission by compound and selected sectors are available for download in 2 formats: • in ASCII format: in ton substance / (0.1 degree x 0.1 degree) /yr. • in netcdf format: in kg substance /m2 /s. The 0.1degree x 0.1 degree grid cells are defined with the lower left corner.
