DS-777 Average Annual Actual Evapotranspiration, 2000 to 2009, in inches estimated from the Simplified-Surface-Energy-Balance (SSEB) Model for the High Plains Aquifer in Parts of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming

The water-budget components geodatabase contains selected data from maps in the,
"Selected Approaches to Estimate Water-Budget Components of the High Plains, 1940
through 1949 and 2000 through 2009" report (Stanton and others, 2011). Data were
collected and synthesized from existing climate models including the Parameter-Elevation
Regressions on Independent Slopes Model (PRISM) (Daly and others, 1994), and the
Snow accumulation and ablation model (SNOW-17) (Anderson, 2006), and used in
soil-water balance models to compute various components of a water budget. The
methodologies used to compute the averages and volumes for the data in this
geodatabase are slightly different for different components and models.
