Black Carbon Emission Data Base for Atmospheric Chemistry and Climate Studies from the Global Emissions Inventory Activity (GEIA)

The Global Emissions Inventory Activity (GEIA) is an activity of the
International Global Atmospheric Chemistry (IGAC) Core Project of the
International Geosphere-Biosphere Program (IGBP). The focus of GEIA
is to make global emissions available on a one degree grid.

A global data base of black carbon emissions to the atmosphere from
fossil fuel combustion has been compiled for atmospheric chemistry and
climate studies. The data base is on a 1 x 1 degree
latitude/longitude grid and is based on the work of Matthews (1983),
Lerner et al. (1988), and Dignon (1992). The original work of Penner
et al. (1993) provides the emissions inventory data on a 5 x 5 degree
grid.

Units of emission yield a global total of 12.6 TgC/y and are given as
the mass in metric tons of carbon for each 1 x 1 degree grid cell.
The emissions are expected to represent the emissions for a typical
mid-1980's year. The distribution is based on national totals and then
mapped to a 1 x 1 degree grid according to the updated population
mapping of Logan (1993).
