This data set provides maps produced from model output data from the National Aeronautics and Space Administration-Â Carnegie Ames Stanford Approach(NASA-Â CASA)model and other modeling approaches. The maps include estimated annual Net Primary Production (ANPP), leaf (live) biomass carbon, wood (live) biomass carbon, fine root (live) biomass carbon, metabolic leaf litter (dead) carbon, structural leaf litter (dead) carbon, woody detritus (dead) carbon, and slow soil carbon, gridded at half-degree spatial resolution for the years 1982-1998, and 2001 (NPP data) for Brazil. Maps are also provided at one-degree resolution for monthly soil emissions and soil uptake of N2O, NO, CO, and CH4.
The input data for the maps were from various sources (see section 5 for more details):
 Carbon storage and NPP data (model output) were from the National Aeronautics and Space Administration- Carnegie Ames Stanford Approach (NASA- CASA) model.
 NO and N2O data were from an expanded version of the Carnegie-Ames-Stanford (CASA) Biosphere model.
 CH4 data were estimated by applying a modified version of Fick s first law based on theoretical computations for diffusivity in aggregated media, together with a soil water balance model run on a one-degree global grid.
 CO data were estimated from:(1)A modified version of Fick s first law for CO uptake by soils and to estimate the production of CO from decaying soils.
(2)Soil CO emissions using as the source, substrate carbon stage estimates for surface soils worldwide from the CASA Biosphere model.
