Resumo: One of the parameters of greatest uncertainty related to water and irrigation management is evapotranspiration. Before selecting the determined method to estimate the reference evapotranspiraton (ETo) in a region, it is extremely important to evaluate the degree of precision of the model. The objective of the present study was to evaluate the performance of 30 methods to estimate the ETo for Chapadão do Sul, Brazil. Meteorological data was obtained from the National Institute of Meteorology during a four year period (2008 to 2011). The standard method was Penman-Monteith-FAO56 and comparison of the results was performed by means of the determination coefficient (r2), the coefficients “a” and “b” of the linear regressions, the estimated standard error (ESE), the Willmott concordance index (d), Pearson correlation coefficient (r) and confidence coefficient (c). The best methods for estimating ETo were obtained by the Penman, Stephens-Stewart, Radiation-Temperature, Turc, Hargreaves, Penman-FAO24, Thornthwaite, Abtew, Blaney-Criddle-FAO24, McCloud, Radiation, Garcia-Lopez, Modify-Thornthwaite, Global-Radiation, Hargreaves-Samani and Jensen-Haise methods. The McCloud method is recommended when only temperature data is used. The Hargreaves-Samani method can be used after calibrating its equation for the region of study. The Makkink, Priestley-Taylor, Camargo, Linacre, Hamon, Ivanov, Kharrufa, Blaney-Morin, McGuiness-Bordne, Romanenko, Lungeon, Hicks-Hess, Liquid-Radiation and Tanner-Pelton methods cannot be applied to estimate the ETo in Chapadão do Sul, Brazil.

Antes da escolha de determinado método para estimativa da evapotranspiração de referência (ETo) em uma região, é de extrema importância avaliar o grau de exatidão do modelo. A presente pesquisa objetivou avaliar o desempenho de 30 métodos para estimativa da ETo para Chapadão do Sul, MS. Os dados meteorológicos foram retirados do Instituto Nacional de Meteorologia no período de quatro anos (2008 a 2011). O método tomado como padrão foi o Penman-Monteith-FAO56; e a comparação dos resultados foi por meio do coeficiente de determinação (r2), dos coeficientes “a” e “b” das regressões lineares, erro-padrão da estimativa (EPE), índice de concordância de Willmott (d), coeficiente de correlação de Pearson (r) e do coeficiente de confiança (c). Os melhores métodos para estimativa da ETo foram: Penman-Original, Stephens-Stewart, Radiação-Temperatura, Turc, Hargreaves-Original, Penman-FAO24, Thornthwaite, Abtew, Blaney-Criddle-FAO24, McCloud, Radiação-FAO24, Garcia-Lopez, Thornthwaite-Modificado, Radiação-Global, Hargreaves-Samani e Jensen-Haise. Quando se tem apenas dados de temperatura, recomenda-se utilizar o método de McCloud. O método de Hargreaves-Samani poderá ser utilizado depois de sua equação receber calibração para a região de estudo. Os métodos Makkink, Priestley-Taylor, Camargo, Linacre, Hamon, Ivanov, Kharrufa, Blaney-Morin, McGuiness-Bordne, Romanenko, Lungeon, Hicks-Hess, Radiação-Líquida e Tanner-Pelton não devem ser utilizados para a estimativa da ETo em Chapadão do Sul.Universidade Federal de Viçosa - UFV2013-04-18info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/reveng/article/view/31310.13083/reveng.v21i2.346Engineering in Agriculture; Vol. 21 No. 2 (2013); 159-172Revista Engenharia na Agricultura - REVENG; v. 21 n. 2 (2013); 159-1722175-68131414-398410.13083/reveng.v21i2reponame:Engenharia na Agriculturainstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/reveng/article/view/313/235Cunha, Fernando França daMagalhães, Fernando FagnerCastro, Marco Aurélio deinfo:eu-repo/semantics/openAccess2023-01-19T13:08:25Zoai:ojs.periodicos.ufv.br:article/313Revistahttps://periodicos.ufv.br/revengPUBhttps://periodicos.ufv.br/reveng/oairevistaengenharianagricultura@gmail.com||andrerosa@ufv.br||tramitacao.reveng@gmail.com|| reveng@ufv.br2175-68131414-3984opendoar:2023-01-19T13:08:25Engenharia na Agricultura - Universidade Federal de Viçosa (UFV)false
