The ORNL DAAC announces the release of a Net Primary Productivity (NPP) compilation that brings together individual detailed site NPP data from the ORNL DAAC holdings in a form that is especially useful for comparative study and ecosystem modeling.
"NPP Multi-Biome: Grassland, Boreal Forest, and Tropical Forest Sites, 1939-1996" offers NPP estimates, vegetation type, and climate information for 53 sites in the ORNL DAAC archive. Selection of the sites was originally based on the availability of consistent NPP and biomass data from the literature. The data set encompasses 34 grasslands, 14 tropical forest sites, and 5 boreal forest sites. Half of the sites include estimates of belowground NPP.
