Through application of a nearest-neighbor imputation approach, mapped estimates of forest biomass density were developed for the contiguous United States using the annual forest inventory conducted by the USDA Forest Service Forest Inventory and Analysis (FIA) program, MODIS satellite imagery, and ancillary geospatial datasets. This data product would contain the following 7 raster maps: Aboveground Forest Biomass, Belowground Forest Biomass, Forest Tree Bole Biomass, Forest Sapling Biomass, Forest Stump Biomass, Forest Top Biomass, Woodland Specias Biomass. All layers have a 250 meter pixel resolution and values represent biomass pounds per acre. The paper on which these maps are based may be found here: https://dx.doi.org/10.2737/RDS-2013-0004 Access to full metadata and other information can be accessed here: https://dx.doi.org/10.2737/RDS-2013-0004 FIA_BelowGroundForestBiomass Wilson, Barry Tyler, Woodall, Christopher W., Griffith, Douglas M. completed USFS Chief Information Office, Enterprise Data Warehouse Please send an e-mail to the address below.

distributor https://doi.org/10.2737/RDS-2013-0004 dataset Validation results suggest strong agreement between the estimates produced from the forest inventory plots and those from the imputed maps, particularly when the carbon pool is closely associated with the imputation model, with weaker agreement for standing dead trees. The level of agreement depends upon scale, as well as thematic resolution, with better results when assessing larger aggregations of carbon pools. Data is complete as of publication. A complete comparative assessment of these raster data, relative to FIA field plot data, can be found in: Wilson, Barry Tyler; Woodall, Christopher W.; Griffith, Douglas M. 2013. Imputing forest carbon stock estimates from inventory plots to a nationally continuous coverage. Carbon Balance and Management. 8:1. Several other raster datasets were used in the development of these data, along with FIA field plot data. Uncertainty in the geographic registration in each of these data sources will contribute to the positional accuracy of the final product. Overall horizontal positional accuracy is expected to be within 1 pixel in either dimension (i.e. 250 meters). The methodology utilized outputs from an ecological ordination model that related live tree measurements made on FIA field plots (response variables) with the associated environmental factors (predictor variables) at each plot location, such as seasonal temperatures and precipitation from the Daymet model, landscape position from the Elevation Derivatives for National Applications dataset, USEPA Level III ecological regions, and vegetation phenology derived from MODIS satellite imagery. These outputs, along with tree canopy cover information from the National Land Cover Dataset, were used to impute forest carbon stock estimates derived for individual field plots to each pixel in the raster map. 2013-01-01T00:00:00 A complete description of the mapping methodology, including data sources used, can be found in: Wilson, Barry Tyler; Woodall, Christopher W.; Griffith, Douglas M. 2013.
