Resumo: This work was aimed at selecting the best methods to estimate the reference evapotranspiration in comparison with the equation of Penman-Monteith-FAO. The methods of evapotranspiration estimation compared were: Jensen-Haise, Ivanov, Linacre, Hargreaves-Samani and Makkink. The analyzed data came from the automatic weather station belonging to the Unidade de Ensino e Pesquisa (Teaching and Research Unit) of the Instituto Federal de EducaÃÃo, CiÃncia e Tecnologia do Cearà - Campus Limoeiro do Norte, CearÃ, comprising the period (in 2007) from January 1st to December. The analysis was based on daily data, monthly data and by ten-day interval data using regression analysis and evaluating the Hoppinks (2002) correlation coefficient, the Willmott (et al., 1985) indexes and the Sentelhas and Campbell (1997) performance index . The results demonstrated that the method of Ivanov gave the best performance in the daily schedule, that in the ten-day schedule the methods of Ivanov and Hargreaves-Samani showed the best performance, and that in the monthly schedule, the methods of Linacre, Hargreaves-Samani and Ivanov showed the best performance. Despite the good performance of the Ivanov method with all three time schedules, we would advise the use of the Hargreaves-Samani method, in ten-day and monthly schedules, due to its greater ease of data collection and practicality in the calculation of reference evapotranspiration.

Os mÃtodos de estimativa de ETo empregados foram: Jensen-Haise, Ivanov, Linacre, Hargreaves-Samani e Makkink. Os dados analisados foram provenientes da estaÃÃo meteorolÃgica automÃtica pertencente à Unidade de Ensino e Pesquisa do Instituto Federal de EducaÃÃo, CiÃncia e Tecnologia do Cearà - Campus Limoeiro do Norte, CearÃ, compreendendo o perÃodo de 1 de janeiro a dezembro de 2007. A anÃlise foi baseada em dados diÃrios, decendiais e mensais, utilizando-se a anÃlise de regressÃo e avaliando o coeficiente de correlaÃÃo por Hoppinks (2002), os Ãndices de concordÃncia de Willmott et al. (1985) e Ãndice de desempenho de Camargo e Sentelhas (1997). Os resultados encontrados expuseram que o mÃtodo de Ivanov obteve o melhor desempenho na escala diÃria. Na escala decendial os mÃtodos de Ivanov e Hargreaves-Samani apresentaram o melhor desempenho. Na escala mensal os mÃtodos de Linacre, Hargreaves-Samani e Ivanov apresentaram o melhor desempenho. Apesar do mÃtodo de Ivanov ter se destacado nas trÃs escalas temporais, propÃem-se a utilizaÃÃo do mÃtodo de Hargreaves-Samani nas escalas decendial e mensal devido a sua maior facilidade de obtenÃÃo dos dados e sua praticidade no cÃlculo da evapotranspiraÃÃo de referÃncia.Conselho Nacional de Desenvolvimento CientÃfico e TecnolÃgicohttp://www.teses.ufc.br/tde_busca/arquivo.php?codArquivo=5317application/pdfinfo:eu-repo/semantics/openAccessporreponame:Biblioteca Digital de Teses e Dissertações da UFCinstname:Universidade Federal do Cearáinstacron:UFC2019-01-21T11:18:25Zmail@mail.com -
