TEM (Terrestrial Ecosystem Model)
|
|
Description
|
The TEM is a process-based ecosystem model that describes carbon and nitrogen dynamics of plants
and soils for terrestrial ecosystems of the globe. The TEM uses spatially referenced information on
climate, elevation, soils, vegetation, and water availability as well as soil- and
vegetation-specific parameters to make monthly estimates of important carbon and nitrogen fluxes
and pool sizes of terrestrial ecosystems. The TEM operates on a monthly time step and at a 0.5°
latitude/longitude spatial resolution.
