This dataset is a Basin Characterization Model (BCM) output using the PCM A2 Scenario for annual actual evapotranspiration, 2010-2039, clipped to the DRECP 12 km buffered boundary. Actual Evapotranspiration: Amount of water that evaporates from the surface and is transpired by plants if the total amount of water is not limited, summed annually. The California Basin Characterization Model (BCM) climate dataset provides historical and projected climate surfaces for the state at a 270 meter resolution. The historical data is based on 4 kilometer PRISM data, and the projected climate surfaces are based on the A2 and B1 scenarios of the PCM and GFDL GCMs. The BCM approach uses a regional water balance model based on...
This dataset represents Runoff change, from Basin Characterization Model (BCM) output using the PCM A2 Scenario in southern Sierra Nevada California, for 2070-2099. The data was processed using historic Runoff (1979-2000) and Runoff (2070-2099) to calculate change. Runoff: Amount of water that becomes stream flow, summed annually. Modeled as amount of water that exceeds total soil storage and rejected recharge. The California Basin Characterization Model (BCM) climate dataset provides historical and projected climate surfaces for the state at a 270 meter resolution.

This dataset is a Basin Characterization Model (BCM) output using the PCM A2 Scenario for Climatic Water Deficit (CWD) in southern Sierra Nevada California, for 2070-2099. 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...

This dataset is a Basin Characterization Model (BCM) output using the GFDL A2 Scenario for average Winter (December, January, February) snowpack, for 2040-2069, clipped to the DRECP 12 km buffered boundary. Snowpack: Amount of snow accumulated per month summed annually, or if divided by 12 average monthly snowpack. This is calculated as prior month's snowpack plus snowfall minus sublimation and snow melt.
