Net Primary Production (NPP) Project


The ORNL DAAC Net Primary Production (NPP) data set collection contains field measurements of biomass and estimated NPP for terrestrial study sites worldwide, compiled from published literature and other extant data sources. Compilation of these data sets was sponsored by the Terrestrial Ecology Program of NASA's Office of Earth Science.

The NPP data set collection contains 82 data sets for 65 intensive study sites broken down by biome as follows:

  • 9 Boreal Forest Sites
  • 35 Grassland Sites
  • 3 Temperate Forest Sites
  • 18 Tropical Forest Sites
  • 2 Tundra Sites

Some combination of above-ground annual peak live biomass data and/or seasonal biomass dynamics data is available for all sites. Many sites also have data on below-ground biomass and/or turnover. A number of previously compiled multi-site, multi-biome data sets of georeferenced NPP estimates are also provided in this data set collection.

The ORNL DAAC NPP Data archive includes data products from the following categories:
