Global Soil Respiration Data

Submitted by ORNL DAAC Staff on 2001-12-06

The ORNL DAAC announces the addition of global annual soil respiration data to its holdings on the physical and chemical properties of soils.

Compiled by J. W. Raich and W. H. Schlesinger, the newly released data set contains soil respiration rates from sites in terrestrial and wetland ecosystems as reported in scientific literature prior to 1992.

The soil respiration rates were measured in a variety of ecosystems to examine microbial activity, nutrient turnover, carbon cycling, root dynamics, and a variety of other soil processes. The respiration rates are reported in terms of grams of carbon per square meter per year.

Biome type, vegetation type, locality, and geographic coordinates are included in the data set.
