Cal-SIMETAW Unit Values
Listed in California Open Data
_Cal-SIMETAW Unit Values_ dataset contains cumulative monthly unit values (per acre) of crop evapotranspiration (ETc), applied water (AW), and six other parameters for the period 2000 – 2015.
Description
Monthly unit values are reported for 20 crops and four non-agricultural land use categories in each Detailed Analysis Unit by County (DAUCo) in California. ETc reflects a well-watered, non-stressed plant condition, and is calculated as the product of reference evapotranspiration (ETo) and the crop coefficient (Kc).
Computed ETc is sensitive to assumptions about Kc and growth dates. Those assumptions can be reviewed in the LUCI files for each DAUCo. **Suggested Application**: Unit values from the overlying DAUCo can be multiplied by land use acreages to compute total ETc or AW for a given study area, which can be used in a water budget or other planning analysis.
