| Resumo: | It was evaluated different methods of estimate of the reference evapotranspiration and made himself the comparison ith the model Penman-Monteith, for some places in the state of oiás and Distrito Federal. They were adjusted equations of lineal egression between this and the models FAO-Penman (Pn), FAORadiation (Ra), and Hargreaves (Hg). Para the studied places an be concluded that the daily values of ETo were better esteemed y the methods of Pn, Hg followed by the Ra, and that both models verestimated ETo when compared with to pattern of PM, what hows the need of the obtaining of local coefficients for best to steem ETo for those models. KEY-WORDS: Evapotranspiration; irrigation; Penman-Monteith. |
