Carbon Data
This data set contains decadal (1950, 1960, 1970, 1980, 1990 and 1995) estimates of gridded fossil-fuel emissions, expressed in 1000 metric tons C per year per one degree latitude by one degree longitude. The CO2 emissions are the summed emissions from fossil-fuel burning, hydraulic cement production and gas flaring. The years 1950 to 1990 were developed and compiled using somewhat different procedures and information than the 1995 data. The national annual estimates (Boden et al., 1996) from 1950 to 1990 were allocated to one degree grid cells based on gridded information on national boundaries and political units, and a 1984 gridded human population map (Andres et al., 1996). For the 1995 data, the population data base developed by Li (1996a) and documented by CDIAC (DB1016: Li, 1996b) was used as proxy to grid the 1995 emission estimates.
Data Provider: Andres, Marland, Fung, Matthews, and Antoinette L. Brenkert

The files have been compressed using the PKZip program. Each uncompressed file contains space-delimited ASCII text with 360 values per line and 180 lines of data (1 degree resolution). Each line is terminated by a newline character. The data are structured so that the upperleft corner of the first pixel is located at 90 North latitude and 180 West longitude. Each pixel represents an 1 by 1 degree area, with the pixel edges falling on whole degree boundaries. These values represent CO2 emissions from fossil fuel burning, hydraulic cement production, and gas flaring in mg of C/cm2/sec.
Each file name is image for a given decade.
Example: co2_emis_1d_1990.asc contains the CO2 emissions for 1990.
