Monthly Fossil-Fuel CO2 Emissions: Isomass of Emissions Gridded by One Degree Latitude by One Degree Longitude

This database presents a monthly time series of the isotopic signature (del 13C) from fossil-fuel CO2 emissions for 1950-2013. Detailed geographic information on CO2 emissions can be critical in understanding the interannual and seasonal patterns of the atmospheric and biospheric response to these emissions. Global, regional, and national annual estimates for 1751 through 2013 were published earlier (Boden et al. 2016). Those national, annual CO2 emission estimates were based on statistics about fossil-fuel burning, cement manufacturing and gas flaring in oil fields as well as energy production, consumption, and trade data, using the methods of Marland and Rotty (1984). The national annual estimates were combined with stable carbon isotopic signatures (del 13C) described in Andres et al. (2000) and with gridded one degree data on political units and 1984 human populations to create the new gridded isotopic time series. Further details on the methodology are provided in Andres et al. (2011).
