BigFoot Data Sets Released

Submitted by ORNL DAAC Staff on 2004-12-16

The ORNL DAAC announces the release of four data sets from the BigFoot Project. These data sets include gridded surfaces of land cover, leaf area index (LAI), Net Primary Production (NPP), and Gross Primary Production (GPP) data from 2000 through 2002 for selected EOS Land Validation Sites. Additional BigFoot data for other sites and years will be released later.

The overall goal of the BigFoot Project was to provide validation of products from the Moderate Resolution Imaging Spectrometer (MODIS) onboard NASA's Earth Observing System (EOS) satellite Terra.

More Southern African Data

Submitted by ORNL DAAC Staff on 2004-11-02

The ORNL DAAC announces the release of fifteen southern African data sets for the Southern African Regional Science Initiative (SAFARI 2000). These data sets, originally prepared in coordination with data investigators by the SAFARI 2000 Data Group at NASA's Goddard Space Flight Center, contain the results of fire-related measurements including field and laboratory measurements of burning biomass emissions, pre- and post-burning site and ash reflectance, estimates of regional fuel load and emissions, and historical fire occurrence.

Nitrogen Deposition Data

Submitted by ORNL DAAC Staff on 2004-09-27

This data set, prepared by Elizabeth Holland and colleagues, contains data for wet and dry nitrogen-species deposition for the United States and Western Europe. Deposition data were acquired directly from monitoring programs in the United States and Europe for time periods from 1978-1994 for wet deposition and from 1989-1994 for dry deposition and evaluated using similar quality assurance criteria to ensure comparability. A standard geostatistical method (kriging) was used to interpolate data onto a 0.5 x 0.5 degree resolution map for wet and dry deposition.
