Abstract
Abstract We used a climate‐driven regression model to develop spatially resolved estimates of soil‐CO 2 emissions from the terrestrial land surface for each month from January 1980 to December 1994, to evaluate the effects of interannual variations in climate on global soil‐to‐atmosphere CO 2 fluxes. The mean annual global soil‐CO 2 flux over this 15‐y period was estimated to be 80.4 (range 79.3–81.8) Pg C. Monthly variations in global soil‐CO 2 emissions followed closely the mean temperature cycle of the Northern Hemisphere. Globally, soil‐CO 2 emissions reached their minima in February and peaked in July and August. Tropical and subtropical evergreen broad‐leaved forests contributed more soil‐derived CO 2 to…
