Explores the effects of atmospheric CO2 enrichment and climate change on soil moisture and biome-level water limitation using a dynamic global vegetation and water balance model forced by five different scenarios of change in temperature, precipitation, radiation, and atmospheric CO2 concentration, all based on the same IS92a emission scenario
Biome level water limitation is defined as the degree to which transpiration and photosynthesis are co-limited by soil water shortage (high values indicate low water limitation).
