The ORNL DAAC is pleased to announce the release of two data sets associated with The North American Carbon Program (NACP):
- NACP Aboveground Biomass and Carbon Baseline Data, V[ersion]. 2 (NBCD 2000), U.S.A., 2000 . Data set prepared by J. Kellndorfer, W. Walker, K. Kirsch, G. Fiske, J. Bishop, L. LaPoint, M. Hoppus, and J. Westfall. The NBCD 2000 (National Biomass and Carbon Dataset for the Year 2000) data set provides a high-resolution (30-m) map of year-2000 baseline estimates of basal area-weighted canopy height, aboveground live dry biomass, and standing carbon stock for the conterminous United States. A mosaic image of biomass at 240-m resolution for the whole conterminous U.S. is also included. This data set supersedes Version 1: NACP Aboveground Biomass and Carbon Baseline Data (NBCD 2000), U.S.A., 2000. In Version 2, previously unaccounted for cover types (e.g., Shrubs, NLCD Type 52) are now included in modeled estimates.
- NACP Integrated Wildland and Cropland 30-m Fuel Characteristics Map, U.S.A., 2010 . Data set prepared by N.H.F. French, D. McKenzie, N. Hamermesh, and J. McCarty. The data set provides a 30-m comprehensive fuelbed characteristics map for both the wildland and cropland areas of the conterminous United States (CONUS) for 2010. This integrated product is the result of combining the spatially discrete Fuel Characteristic Classification System (FCCS) data of the US Forest Service (USFS) with the crop-and grassland-specific information of the US Department of Agriculture’s (USDA's) Cropland Data Layer (CDL).
The North American Carbon Program (NACP) is a multi-disciplinary research program designed to obtain scientific understanding of North America's carbon sources and sinks and of the changes in carbon stocks needed to meet societal concerns, and to provide tools for decision makers. NACP began in 2002 and continues to date. The NACP data collection contains continental carbon budgets, dynamics, processes, and management of the sources and sinks of carbon dioxide, methane, and carbon monoxide in North America and in adjacent ocean regions.
The ORNL DAAC is a NASA-funded data center archiving and distributing terrestrial ecology and biogeochemical dynamics data.
