Class A pan coefficients (Kp) to estimate daily reference evapotranspiration (ETo) Coeficientes do tanque Classe A (Kp) para a estimativa diária da evapotranspiração de referência (ETo)

Revista Brasileira de Engenharia Agrícola e Ambiental, 2003
The class A pan coefficient (Kp) has been used to convert pan evaporation (ECA) to grass-reference evapotranspiration (ETo), an important component in water management of irrigated crops. There are several methods to determine Kp values, using wind speed,
