This dataset from the North American Carbon Program (NACP) contains annual estimates of carbon stocks, fluxes, and productivity over forested land in 11 states of the western USA (Arizona, California, Colorado, Idaho, Montana, Nevada, New Mexico, Oregon, Utah, Washington, and Wyoming). The estimates were produced from multiple simulations using the Community Land Model (v4.5) with different climate forcing data and prescribed harvest rates. The estimates span two modeled time periods, 1979-2014 and 2015-2099, at 1/24-degree (4 km x 4 km) resolution. Variables included are gross primary production, net ecosystem exchange, net ecosystem productivity, net primary production, autotrophic respiration, heterotrophic respiration, transpiration factor, aboveground live tree carbon, carbon loss from fire, allocation to stem carbon, and burned area fraction.
The NACP is a multidisciplinary research program designed to improve understanding of North America's carbon sources, sinks, and stocks. The central objective is to measure and understand the sources and sinks of carbon dioxide, methane, and carbon monoxide in North America and adjacent oceans. See all data from NACP.
