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.

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.

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.

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.

The ORNL DAAC announces that data about atmospheric fluxes in the Arctic tundra are now available on-line.

Three data sets from the Southern African Regional Science Initiative (known as "SAFARI 2000") are now accessible from the ORNL DAAC Web site.

The ORNL DAAC announces that soil data from Phase 1 of the Vegetation/Ecosystem Modeling and Analysis Project (VEMAP) have been revised. Data providers corrected some water holding capacity (WHC) files in the data set entitled "VEMAP 1: U.S. Soil."
