This dataset is a Basin Characterization Model (BCM) output using the GFDL A2 Scenario for Climatic Water Deficit (CWD) in northern Sierra Nevada California, for 2010-2039. The term climatic water deficit defined by Stephenson (1998) is quantified as the amount of water by which potential evapotranspiration (PET) exceeds actual evapotranspiration (AET). This term effectively integrates the combined effects of solar radiation, evapotranspiration, and air temperature on watershed conditions given available soil moisture derived from precipitation. Climatic water deficit can be thought of as the amount of additional water that would have evaporated or transpired had it been present in the soils given the temperature...
