Seasonal Data

Seasonal ETo, Peff, and ETF data are provided for calculating agricultural variances for suppliers that have qualifying urban agriculture acreage in their service area. Seasonal values are weighted average values that are calculated based on crop acreages within the service area boundaries. Crop acreages are derived from DWR’s land use data layer (CADWR Land Use Viewer - https://gis.water.ca.gov/app/CADWRLandUseViewer/?page=home). The evapotranspiration fraction (ETF) was calculated from weighted average values of crop coefficient (Kc) and irrigation efficiency (IE), which are also provided in this file.
