Net Biome Production (g C m-2 y-1) under the A2 Emission Scenario (with land use), 8km

Net biome production (g C m-2 y-1) with potential vegetation simulated by the MC2 dynamic global vegetation model and projected land use, averaged across 3 CMIP3 climate projections (CSIRO, MIROC and CGCM3) under the A2 emission scenario, per decade over the 21st century.

Net biome production is defined as the difference between net ecosytem production and losses through disturbances such as fire emissions and insect damage. In the case of MC2, fire is the only disturbance to be accounted for. Net ecosystem production is the difference between net primary production and heterotrophic (soil) respiration. Net primary production is the difference between gross primary production and autotrophic (plant) respiration.

We acknowledge the World Climate Research Programme's Working Group on Coupled Modelling, which is responsible for CMIP (Climate Model Intercomparison Project), and the climate modeling groups for producing and making available their model output. For CMIP, the U.S. Department of Energy's Program for Climate Model Diagnosis and Intercomparison provides coordinating support and led development of software infrastructure in partnership with the Global Organization for Earth System Science Portals.
