The ORNL DAAC has recently made the Matthews Global Vegetation Data available.

The climate data at the ORNL DAAC are used primarily as driving variables in terrestrial biogeochemistry models.

The soil data at the ORNL DAAC are used primarily as site characteristics for terrestrial biogeochemistry models. The goal is to have data sets that contain the following variables:

The ORNL DAAC has recently made additional climate data available. Please return to our main page and search under Data Available for the data of interest.

UPGRADE - On Monday, March 8, 1999, the ORNL DAAC operational system will be unavailable because of a system upgrade. We expect to be operational again by late Monday afternoon. Please check this hotnews again for updates.

VEMAP-1 Database - The Vegetation/Ecosystem Modeling and Analysis Project (VEMAP) is an ongoing multiinstitutional, international effort addressing the response of biogeography and biogeochemistry to environmental variability in climate and other drivers in both space and time domains.

Another 18 study sites, plus a worldwide data set, have been added to the global terrestrial Net Primary Production (NPP) reference database.

A Global River discharge dataset, which contains monthly averaged discharge measurements for 1018 stations located throughout the world, is now available from the ORNL DAAC. The data were originally compiled by C. J. Vorosmarty and B.M.

Graphs of biomass dyanmics and climate data for grassland sites have been added to the global terrestrial Net Primary Production (NPP) reference database at the ORNL DAAC.

A web site is now available for the Land Validation project. It was created with the purpose of facilitating communication among MODIS Land Validation Principal Investigators and other interested parties.

There is also some data available.
