The Ecosystem Model-Data Intercomparison (EMDI) activity will provide, for the first time ever, a formal opportunity for a wide range of global carbon cycle models to be compared with measured net primary production (NPP). The goals of the EMDI are to compare model estimates of terrestrial carbon fluxes (NPP and net ecosystem production (NEP), where available) to estimates from ground-based measurements, and improve our understanding of environmental controls of carbon allocation. The primary questions to be addressed by this activity are to test simulated controls and model formulation on the water, carbon, and nutrient budgets with the observed NPP data providing the constraint for autotrophic fluxes and the integrity of scaled biophysical driving variables.
