Anthropogenic emissions (containing 15 sectors) are based on national activity data (fuelwood combustion per year), emission factors (kg CO/ kg fuelwood combusted par activity), and grid maps (e.g. population maps) for spatial distribution of the emissions within a country. Biomass burning emissions are estimated with a climatology from Hao et al. (1994), and ATSR active fire maps are used for the spatial and temporal distribution of the emissions. Biogenic emissions are estimated with a vegetation canopy model.
