A compilation of net primary productivity (NPP) estimates for grasslands has come on-line at the ORNL DAAC. Users will find the compilation handy for comparative study and ecosystem modeling.

A revised version of gridded net primary productivity (NPP) estimates is now available from the ORNL DAAC.

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.

The ORNL DAAC announces the release of a data set entitled "Literature-Derived Parameters for the BIOME-BGC Terrestrial Ecosystem Model."

The ORNL DAAC announces the release of a data set entitled "Effects of Elevated Carbon Dioxide on Litter Chemistry and Decomposition."

The ORNL DAAC now offers seven additional data sets prepared for the Southern African Regional Science Initiative ("SAFARI 2000"). The data sets mainly pertain to soils but also include atmospheric and climate data.

Mercury, a Web-based search system at the ORNL DAAC, provides a window into land validation data from around the world. The data are primarily collected at field sites for comparison with satellite-derived products.

The ORNL DAAC announces that 10 additional data sets prepared for the Southern African Regional Science Initiative ("SAFARI 2000") and their documentation are available on-line. The data were earlier released on CD-ROM.

Over 130 data sets related to regional and global biogeochemical dynamics can now be located and acquired through the Mercury metadata search system at the ORNL DAAC. Thirty-five data sets were added in the past 3 months.

Six additional data sets prepared for the Southern African Regional Science Initiative ("SAFARI 2000") are now available on-line from the ORNL DAAC, along with their documentation. The data were earlier released on CD-ROM.
