Use of the ASCE Standardized Reference et Equation by agricultural weather networks in the western U.S. Current status and future challenges

Abstract

The procedures used by the public agricultural weather networks to estimate reference evapotranspiration (ETref) in the western United States were assessed to determine how many networks have adopted the ASCE Standardized Reference Evapotranspiration Equation ETszEQ. Five states now use the ETszEQ to generate ETref values. Several additional procedures are used to estimate ETref in the region. The most widely used procedures are 1982 Kimberly Penman Equation and the Nebraska Penman Equation. ETref values computed using these two Penman Equations were found to be similar to ETref values computed using the ETszEQ, suggesting a switch to the ETszEQ would not cause serious problems with existing irrigation management/crop water use programs in states using these two Penman Equations.
