Information for Area Source Data Files

The zipped files provided here are ASCII Grid format files, which can be used in most GIS software. Each zip file contains pollutant-specific gridded emissions for year 2019 by CORINAIR SNAP sectors. Note that some pollutants might not contain emission maps on some sectors (not all sectors generate emissions).

The sectors are labelled as follows:

energyprod - SNAP 01 (Combustion in Energy Production and Transformation)
domcom - SNAP 02 (Combustion in Commercial, Institutional, Residential and Agriculture)
indcom - SNAP 03 (Combustion in Industry)
indproc - SNAP 04 (Production Processes)
offshore - SNAP 05 (Extraction and Distribution of Fossil Fuels)
solvents - SNAP 06 (Solvent Use)
roadtrans - SNAP 07 (Road Transport)
othertrans - SNAP 08 (Other Transport and Mobile machinery)
waste - SNAP 09 (Waste Treatment and Disposal)
agric - SNAP 10 (Agriculture, Forestry and Landuse Change)
nature - SNAP 11 (Nature)
totarea - Total area sources (sum of all the above grids)
total - Total emissions (including point sources)

Important note about data uncertainty

The CH4 maps show high uncertainty because a large proportion of the emissions (about 44%) are from the agriculture sector which has a high level of uncertainty associated with its emissions and even though all the data is collected and originally produced outputs of the data in 1x1km, due to non-disclosure constraints, the data have been aggregated at 5x5km resolution. As a result, by evenly distributing the 5x5km maps in 1x1km maps, there is a loss in data quality.
