FIALHO DOS REIS, Edvaldo et al. COMPARATIVE STUDY OF THE ESTIMATE OF THE EVAPORATE TRANSPIRATION REGARDING THE THREE LOCALITY STATE OF ESPIRITO SANTO DURING THE DRY PERIOD. Idesia [online]. 2007, vol.25, n.3, pp.75-84. ISSN 0718-3429.  http://dx.doi.org/10.4067/S0718-34292007000300008.

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 weather conditions from the municipalities of Sooretama, Cachoeiro de Itapemirim and Venda Nova do Imigrante located, respectively, in the north, south and mountainous regions of the Espírito Santo state. Weather variables regarding the dry period (June, July and August) in 2006 were used. 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. To make a comparison between the values of ETo estimated by the empirical equation and the universal standard method Penman-Monteith (FAO 56) there were considered the regression equation parameters ß0 e ß1, 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 studied in the three localities. For the weather conditions where the work was done, according to the dry and rainy periods, the best methods were: Penman 48 Original, Priestley-Taylor (PT), FAO24 Penman Modificado, FAO24 Blaney-Criddle, Turc (61), FAO24 Radiação, Makkink (Mk).

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