Change in Average Climatic Water Deficit

Change in Average Annual Climatic Water Deficit - Near Future - Drier. This raster dataset represents a projection of the difference in the mean annual climatic water deficit between the baseline period (1950-1980), and a near future period ( 2030-2059) under the MIROC (Drier) scenario of climate change. It is only available for the Southern California Region.

creation_method The climate variable in this layer is the change in average annual accumulated climatic water deficit relative to a baseline period. Climatic water deficit (CWD) measures the evaporative demand that exceeds available water, reflecting the impacts of available water or drought stress on plants. Higher CWD indicates a higher level of drought stress. Baseline annual accumulated CWD was averaged between 1950-1980 Near Future shows the average change in CWD as modeled for 2030-2059 Drier future projections were generated using the MIROC5 climate model under the business as usual RCP 8.5.
