What is Thornthwaite Equation?

The Thornthwaite (1948) equation is a widely used empirical method for estimating potential evapotranspiration (PET). The equation only requires the mean monthly air temperature and mean daily daylight hours for each month, which can be calculated from latitude.

What is Thornthwaite Method?

Potential evapotranspiration (PET) is estimated via the method of Thornthwaite. The only variable used is monthly temperature [t (C)]. Generally, the Thornthwaite method underestimates PET in the arid areas and overestimates PET in the humid areas.
