The Second NPP Model Intercomparison Workshop was held at Potsdam Institute for Climate Impact Research (PIK), Potsdam, Germany in June 1995. The purpose of the meeting was to compare models simulating terrestrial NPP and their outputs at the global scale. Sixteen modeling teams presented their models and NPP model outputs for analysis. The scientific sponsorship of this workshop was jointly provided by IGBP_DIS, GAIM and GCTE.
The following images represent:
Water
balance coefficient (WBC). WBC was employed to test the hypothesis stating that
the water availability is the primary driver of NPP across the models. Difference
between annual average precipitation and potential evapotranspiration (PREC-PET)
was used to calculate WBC.
Climate
space of structural vegetation classes, as they defined for BIOME-BGC vegetation
classification.
Annual
average NPP. This image represents the result of averaging the NPP outputs of
16 models at the global scale.
Areas
of dominant environmental controls on NPP. Water availability (WBC) and annual
average temperature were used to determine these areas.
