Considerações sobre a evapotranspiração potencial medida e calculada no município de Goiânia e circunvizinhos

Abstract

ln this paper the author compared the poten­cial evapotranspiration calculated by methods of THORNTH - WAITE, CAMARGO, HOLDRIDGE, BLANEY-CRIDDLE, GRASSI-CHRISTI­ANSEN and GARCIA-LOPEZ, with the direct measurement from the evapotranspirometer of THORNTHWAITE & MATHER, in Goiâ nia (Goiâs-Brazil) county and suounding counties. All the methods studied presented a sígnificante correlation when compared with the measured data The correlation coeffícients 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**.
