Carbon Data
The EDGAR (Emission Database for Global Atmospheric Research) database project is a comprehensive task carried out jointly by the National Institute for Public Health (RIVM) and the Netherlands Organization for Applied Scientific Research (TNO) and stores global emission inventories of direct and indirect greenhouse gases from anthropogenic sources including halocarbons and aerosols both on a per country and region basis as well as on a grid (see http://www.rivm.nl/edgar/ [Internet Link]). For the ISLSCP Initiative II data collection, gridded global annual anthropogenic emissions for the greenhouse gases CO2, CH4, N2O are provided on a 1-degree by 1-degree grid for the years 1970, 1980, 1990, and 1995 and for the tropospheric ozone precursor gases CO, NOx, NMVOC (Non-Methane Volatile Organic Compounds) and SO2 for the years 1990 and 1995.

The original data files submitted to the ISLSCP II staff were ASCII data tables, containing the total anthropogenic emissions of the various gases shown above. These original data files contain a 12-13 line header and 3 columns of data: Longitude, Latitude, and the emissions data for that cell. The file names contain the word "data".
The ISLSCP II staff also used the coordinates given in the original tabular data to create two-dimensional ASCII map files for each gas on a 1-degree by 1-degree Earth grid. These files are named in a similar fashion as the table names above except that they contain the word "map" as opposed to the word "data" and the file extension is ".asc" indicating that this is an ASCII map. As an example,
the file named edgar_co2_map_1d_1980.asc contains the CO2 anthropogenic emissions for 1980 mapped onto a 1-degree by 1-degree grid and is based on data from the original data table named edgar_co2_data_1d_1980.csv.
