- The input data were monthly soil moisture content; there are 16 models with a total of 73 ensemble members. -The Western U.S. includes 8 regions and basins: Pacific Northwest, California Klamath, Great Basin, Colorado River Basin, Rio Grande, Missouri River Basin, Arkansas-Red, and West Gulf. - There are two emission scenarios: higher emission scenario (A2) and lower emission scenario (B1) - Three periods selected: base 1971-2000, mid-century 2041-2070, and end-of-century 2070-2099. For each period, long-term mean SMC is computed for each scenario. The future to base period percent change is drawn on map.

For each scenario and each future period, the percent change is calculated by: {[futureMean – baseMean]/baseMean}x100

The duration of this activity was 160 hours.
