ECOSYSTEM MODEL EVALUATION Rachel Powers TEM-Terrestrial Ecosystem Model of Biogeochemical Dynamics Marine Biological Laboratory (MBL), Woods Hole, MA University of New Hampshire (UNH) http://ecosystems.mbl.edu/tem/ Domain/Objective TEM is a process-based ecosystem model that describes carbon, nitrogen and water dynamics of plants and soils for terrestrial ecosystems of the globe. Key Assumptions Vegetation is not segregated into functional tissues Detritus (soil) is not partitioned into age or quality classes Vegetation and detritus are distributed evenly within grid cells Temporal/Spatial Scale The TEM normally operates on a monthly time step and at a 0.5 degrees latitude/longitude spatial resolution, but has been applied at finer spatial resolutions (down to 1 hectare).
