Central Valley Hydrologic Model version 2 (CVHM2): Model Array of Climate Data (Precipitation, Evapotranspiration)

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2023-06-14T00:00:00Z
This data release consists of climate data from the Basin Characterization Model v8 (BCMv8) for the updated Central Valley Hydrologic Model (CVHM2) for water years 1922-2019. The BCMv8 data are available in separate data release titled "The Basin Characterization Model - A regional water balance software package (BCMv8) data release and model archive for hydrologic California, water years 1896-2020". The data were modified by: (1) clipping the data within the modeled area and modeled time frame, and (2) assigning values from the 270-meter BCMv8 grid to the1-mile CVHM2 model grid for the hydrologic variables precipitation and potential evapotranspiration.
