VEMAP

Vegetation-Ecosystem Modeling and Analysis Project

The Vegetation-Ecosystem Modeling and Analysis Project (VEMAP) was a multi-institutional, international effort whose goal was to evaluate the sensitivity of terrestrial ecosystem and vegetation processes to altered climate forcing and elevated atmospheric CO2. 

Phase 1 of the VEMAP project developed a model database of climate, soils, and vegetation. Phase 2 developed a historical (1895-1994) gridded dataset of climate (temperature, precipitation, solar radiation, humidity, and wind speed) and transient climate change scenarios based on coupled atmosphere-ocean general circulation model (GCM) experiments.
