Efficiency of methods for calculating class A pan coefficients to estimate evapotranspiration reference
The class A pan coefficients (Kp) can be determined with several methods, most based on wind speed, relative humidity and conditions and extension of the border which circles the pan.This study aimed at evaluating the performance of methods used for estimating the Kp, as well as an average and constant Kp (0.70), to evaluate the reference evapotran
