A Dynamic Global Vegetation Model (DGVM) is a computer program that simulates shifts in potential vegetation and its associated biogeochemical and hydrological cycles as a response to shifts in climate. DGVMs use time series of climate data and, given constraints of latitude, topography, and soil characteristics, simulate monthly or daily dynamics of ecosystem processes. DGVMs are used most often to simulate the effects of future climate change on natural vegetation and its carbon and water cycles.
MC1 is a dynamic global vegetation model that has been used since the mid-1990s but has not been documented extensively enough to be recognized as a well published model. Book editors and authors would like to make better known the many project results that illustrate its value and the various ways they have been engaged to "translate" the model results into valuable currency for managers. They quote that "Our user base is increasing and we have started training per request."
