Synopsis

Synopsis

Measurements of potential evapotranspiration indicate that mean temperature cannot be relied upon for general use in estimating evapotranspiration during short-periods. Mean temperature methods can be used with limited success for long-period (growing season, and annual) estimates of potential evapotranspiration, but energy balance methods are preferable if radiation data are available.
