Abstract

In this paper the author compared the potential evapotranspiration calculated by methods of THORNTHWAITE, CAMARGO, HOLDRIDGE, BLANEY-CRIDDLE, GRASSI-CHRISTIANSEN and GARCIA-LOPEZ, with the direct measurement from the evapotranspirometer of THORNTHWAITE & MATHER, in Goiânia (Goiás-Brazil) and surrounding counties. All the methods studied presented a significant correlation when compared with the measured data. The correlation coefficients were: THORNTHWAITE, r = 0.96, CAMARGO, r = 0.94, HOLDRIDGE, r = 0.94, BLANEY-CRIDDLE, r = 0.91, GRASSI-CHRISTIANSEN, r = 0.70, GARCIA-LOPEZ, r = 0.62.
