BigFoot Data Set Available

Submitted by ORNL DAAC Staff on

The ORNL DAAC announces the release of "BigFoot Field Data for North American Sites, 1999-2003".

This data set reports measurements of fraction of photosynthetically active radiation (FPAR), nitrogen content, allometric equations, root biomass, leaf area index (LAI), tree biomass, soil respiration, and net primary productivity (NPP) field data in comma-separated ASCII files for selected EOS Land Validation Sites in North America from 1999 to 2003. Additionally, derived landcover images and vegetation inventories are provided in GEOTIFF format.

The study sites included in the data set are listed below by site name and biome:

  • BOREAS NSA, Canada (NOBS) - boreal forest
  • Bondville, Illinois, USA (AGRO) - cropland
  • Harvard Forest LTER, Massachusetts, USA (HARV) - temperate mixed forest
  • Konza Prairie LTER, Kansas, USA (KONZ) - tallgrass prairie
  • Sevilleta LTER, New Mexico, USA (SEVI) - desert
  • Barrow, Alaska, USA (TUND) - Arctic tundra

The goal of the BigFoot project was to use in situ measurements, remote sensing, and models to validate Moderate Resolution Imaging Spectrometer (MODIS) products from NASA's Earth Observing System (EOS) Terra and Aqua satellites. See our BigFoot Project Page for further information.
