One of the goals of the North American Carbon Program is to develop a quantitative scientific basis for large-scale carbon accounting to reduce uncertainties about the carbon cycle component of the climate system. In support of this goal, the National Biomass and Carbon Dataset 2000 (NBCD 2000), a high-resolution, ecoregional database of circa-2000 canopy height, aboveground biomass, and carbon stocks for the conterminous U.S., has been developed. Area-based estimates of terrestrial aboveground live dry (ALD) biomass and carbon were produced using estimates of both horizontal and vertical vegetation structure. Given the complementary nature and quasi-synchronous data acquisition of the InSAR 2000 Shuttle Radar Topography Mission (SRTM), the Landsat-based 2001 National Land Cover Database (NLCD), and data sets from the national LANDFIRE project, this project exploits synergies afforded by the fusion of these high-resolution data sources. Whereas the thematic layers of the NLCD and LANDFIRE projects were suitable for characterizing horizontal vegetation structure (type and density), the SRTM acquisition, in conjunction with the National Elevation Dataset (NED), provided information relating to the vertical structure (canopy height). Field reference data obtained from the USDA Forest Service - Forest Inventory and Analysis (FIA) network of sample plots were used to drive tree-based regression models used in height and biomass predictions. The NBCD 2000 project followed the ecoregional mapping-zone approach employed by the NLCD and LANDFIRE projects. For each of the 66 zones comprising the conterminous U.S., high-resolution (30-m) maps of canopy height and aboveground biomass together with error estimates are available online (http://whrc.org/NBCD).
