The i12_CalSim_Output dataset is a point feature class containing 44 point locations representing a subset of CalSim II output locations. A related table of timeseries data is provided that corresponds to each of these point locations. Timeseries data reflect a simulation period from 10/31/1921 through 9/30/2003 as simulated by the CalSim II model. Multiple CalSim II model simulations are included to reflect projected changes in climate for early-century (2030) and late-century (2070) model simulations (including 2070 drier extreme warming [DEW] scenario and wetter moderate warming [WMW] scenario). Spatial references were developed during the Water Storage Investment Program (WSIP) climate change study conducted in 2016. The user should use caution and fully understand the limitations of these datasets before applying them in a water budget calculation as these datasets correspond to model simulation outputs that contain their own assumptions and limitations.
