Eto = reference evapotranspiration or potential evapotranspiration referenced to grass.
Crop Coefficient uses growing degree days (GDD) accumulated from planting based on the
averaging method of calculating GDD
with a maximum temperature cutoff of 86F and a minimum cutoff temperature of 50
F. The
Base Temperature is 50 F.
The reference for this work is Crop Coefficients
by Israel Broner from Irrigation Scheduling : The water Balance
Approach Colorado State University Cooperative Extension No. 4.707 1994
The Crop coefficient was referenced to alfalfa so it was multiplied by
1.15 to use with potential evapotranspiration (PET) referenced to grass which is
the PET on New Mexico interent site.
