National Biomass Data Set Now Available

by Matt Ball on April 21, 2011

The Woods Hole Research Center has just released a new high-resolution data set for the conterminous United States for canopy height, aboveground biomass, and carbon stock for all forests and woodlands. The National Biomass and Carbon Dataset (NBCD) provides forest attributes at a 30 m resolution, with digital raster data now freely accessible.

Researchers divided the 48 states into 66 ecoregional mapping zones, and compiled spatial data from NASA space-borne imagery (SRTM/Landsat-7), land use/land cover information (NLCD 2001), topographic survey data (NED), and extensive forest inventory data (FIA). This data, along with fieldwork observations, was then analyzed to generate the canopy height, aboveground biomass, and carbon stock maps, which were then joined to form national-scale products.

The project was initiated in 2005 with funding from NASA’s Terrestrial Ecology Program as well as support from the USGS/LANDFIRE consortium. Collaborators included the U.S. Forest Service Forest Inventory and Analysis (FIA) Program, and the National Land Cover Database (NLCD 2001) and National Elevation Dataset (NED) project teams at the USGS EROS Data Center.
