Estudo comparativo de modelos de estimativa da evapotranspiração de referência para algumas localidades no estado de Goiás e Distrito Federal

Resumo

It was evaluated different methods of estimate of the reference evapotranspiration and made himself the comparison with the model Penman-Monteith, for some places in the state of Goiás and Distrito Federal. They were adjusted equations of lineal regression between this and the models FAO-Penman (Pn), FAORadiation (Ra), and Hargreaves (Hg). Para the studied places can be concluded that the daily values of ETo were better esteemed by the methods of Pn, Hg followed by the Ra, and that both models overestimated ETo when compared with to pattern of PM, what shows the need of the obtaining of local coefficients for best to esteem ETo for those models.
