Dataset was scientifically peer reviewed
Description:
This dataset represents aboveground carbon (calculated as 50 % of total aboveground live biomass) at 30 arc second (~ 1 km) resolution, downsampled from the NBCD2000 240 m FIA dataset for the contiguous United States. Pixel values are total NBCD2000-estimated carbon (in metric tonnes) per cell, calculated by sum aggregation from original data. The projection is GCS WGS84.


Original National Biomass and Carbon Dataset 2000 (NBCD2000) Abstract: 

Scientists at the Woods Hole Research Center have produced a high-resolution “National Biomass and Carbon Dataset for the year 2000” (NBCD2000), the first ever spatially explicit inventory of its kind. The dataset was produced as part of a project funded under NASA’s Terrestrial Ecology Program with additional support from the Landscape Fire and Resource Management Planning Tools Project (LANDFIRE). The project has generated a high-resolution (30 m), year-2000 baseline estimate of basal area-weighted canopy height, aboveground live dry biomass, and standing carbon stock for the conterminous United States. 

Development of the dataset is based on an empirical modeling approach that combines USDA Forest Service Forest Inventory and Analysis (FIA) data with high-resolution InSAR data acquired from the 2000 Shuttle Radar Topography Mission (SRTM) and optical remote sensing data acquired from the Landsat ETM+ sensor. Three-season Landsat ETM+ data were systematically compiled by the Multi-Resolution Land Characteristics Consortium (MRLC) between 1999 and 2002 for the entire U.S. and were the foundation for development of both the USGS National Land Cover Dataset 2001 (NLCD 2001) and the LANDFIRE project. Products from both the NLCD 2001 (landcover and canopy density) and LANDFIRE (existing vegetation type) projects as well as topographic information from the USGS National Elevation Dataset (NED) are used within the NBCD 2000 project as spatial predictor layers for canopy height and biomass estimation. Forest survey data provided by the USDA Forest Service FIA program were made available to the project under a national Memorandum of Understanding. The response variables (canopy height and biomass) used in model development and validation were derived from the FIA database. Production of the NLCD 2001 and LANDFIRE projects was based on a mapping zone approach in which the conterminous U.S. is split into 66 ecoregionally distinct mapping zones. This approach was also adopted by the NBCD 2000 project. Data products are provided on a zone-by-zone basis.

FAIR DATA USE POLICY: With the completion of the NBCD datasets, it is the Project Team's interest to provide access to the data as soon as possible. By downloading data from the National Biomass and Carbon Dataset (NBCD) you acknowledge a FAIR DATA USE POLICY in line with data sharing policy under the North American Carbon Program: The data provided on this site are freely available and were furnished by individual scientists who encourage their use. Please kindly inform in writing (or e-mail) the NBCD Team of how you are using the data and of any publication plans. If not yet published, please reference the source of the data, as a citation and in the acknowledgments (See below for dataset citation). The NBCD Team will tell you if they feel they should be acknowledged or offered participation as authors. We assume that an agreement on such matters will be reached before publishing and/or use of the data for publication. If your work directly competes with an ongoing investigation, the NBCD Team may ask that they have the opportunity to submit a manuscript before you submit one that uses their data. When publishing, please acknowledge the agency that supported the research (NASA Terrestrial Ecology Program). We kindly request that those publishing papers using any data from NBCD to supply reprints to the NBCD Team.
