Abstract

We used an ecosystem process simulation model, BIOME-BGC, in a sensitivity analysis to determine the factors that may cause the dry matter yield (Eϵ), and hence, annual net primary production to vary for different ecosystems. At continental scales, e was strongly correlated to annual precipitation. At a single location, year-to-year variation in NPP and E was correlated to either annual precipitation and minimum air temperatures. Simulations indicated that forests had lower eϵ than grasslands. The most sensitive parameter affecting forest E was the total amount of living woody biomass, which affects NPP by increasing carbon loss by maintenance respiration. Thus, a global map of woody biomass should significantly improve estimates of global NPP using remote sensing.
