agrimet uses the 1982 kimberly penman et model
AgriMet uses the 1982 Kimberly-Penman ET model
  • Developed by USDA Agricultural Research Service in Kimberly, Idaho
  • Alfalfa based reference model
crop coefficients relate reference et to crop specific et
Crop coefficients relate reference ET to crop specific ET:

ETc = ETrx Kc

ETc Specific Crop Consumptive Use

ETr Reference Evapotranspiration (Alfalfa)

Kc Crop Coefficient (varies with time)
