BRAGANCA, Rosembergue; FIALHO DOS REIS, Edvaldo; GARCIA, Giovanni de Oliveira  y  MACEDO PEZZOPANE, José Eduardo. COMPARATIVE STUDY OF THE ESTIMATIVE EVAPOPERSPIRATION IN REFERENCE TO THE WET PERIOD FOR THREE LOCALITIES ON THE STATE OF ESPÍRITO SANTO. Idesia [online]. 2010, vol.28, n.2, pp.21-29. ISSN 0718-3429.  http://dx.doi.org/10.4067/S0718-34292010000200003.

This work had the objective of a comparative study of the empirical equations for the estimate of the reference evapotranspiration in comparison to Penman-Monteith FAO 56 universal standard method for the conditions climate from the municipalities of Sooretama, Cachoeiro de Itapemirim and Venda Nova do Imigrante located, respectively, in the north, south and mountainous regions of the state Espírito Santo. Climate variables were used referent to this dry period (June, July and August) in 2006. They were obtained from data platform of CPTEC-INPE from the agrometeorological automated stations code number 31957, 31958 and 31959 installed respectively, in the municipalities showed. Making a comparation between the values of ETo estimated by the empirical equation and the universal standard method Penman-Monteith FAO 56 were considered the regression equation parameters β0 and β1, determination coefficient r2, correlation coefficient r, standard of the error estimate EEP, the agreement index d, confidence or performance index c, in the diary scales, three, five and seven days, for the months studies in the three localities. To the three places studied in the rainy dry period, they stood out as better methods in the order Penman 48 Original, Priestley-Taylor, FAO 24 Penman Modify, FAO 24 Blaney-Criddle, Turc (61), FAO 24 Radiation, Makkink.

Palabras clave : Climatic variables; empiric equations; reference evapotranspiration.
