Resumo: | Evapotranspiration is one of the key factors determining efficiency of irrigation management. In the absence of climate data, the choice of a model for its estimation should be strictly criteria based. In this study the performance of nine methods of estimating potential evapotranspiration (ETp) in the northern Recife/PE were evaluated, using the data collected from a weather station and “Class A” pan located in the Federal Rural University of Pernambuco during the period of 2009 and 2011. Estimated data were correlated by linear regression, using FAO-Penman-Monteith method as standard. Performance of methods was based on correlation coefficients “r”, agreement “d” of Willmott and the performance index “c”. The best ETp estimates were obtained by the methods of solar radiation, Camargo, and Makkink and Priestley-Taylor, all with “c” index between 0.80 and 0.98, considered good to best. The methods of Hargreaves-Samani and Blaney-Criddle had “c”index in the range of 0.6 to 0.89, varying according to the mean of one, three, seven and ten days. The methods “Class A” pan, and Linacre had lowest “c” indexes varying between 0.40 and 0.70. |

Avaliou-se o desempenho de nove métodos de evapotranspiração de referência (ETp) na região norte da cidade de Recife/PE, através de dados coletados de uma estação meteorológica e tanque “Classe A” localizados na Universidade Federal Rural de Pernambuco entre os anos de 2009 e 2011. Os dados estimados foram correlacionados por meio de regressão linear tendo como padrão o método Penman-Monteith-FAO 56. A avaliação de desempenho dos métodos foi baseada nos coeficientes de correlação “r” de concordância “d” de Willmott e o índice de desempenho “c”. As melhores estimativas de ETp para as condições climáticas de Recife foram obtidas pelo método de Radiação solar, Camargo, Makkink e Priestley-Taylor, todos com índice de desempenho entre 0,80 e 0,98 (bom a ótimo). Os métodos de Hargreaves-Samani e Blaney-Criddle tiveram índices de desempenho entre bom e regular (0,80 a 0,60). Os métodos de ETp do tanque Classe A e Linacre obtiveram os piores índices de desempenho “c” (de 0,40 a 0,70) dentre todas as avaliações realizadas.Universidade Federal de Viçosa - UFV2012-04-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/reveng/article/view/26210.13083/reveng.v20i2.291Engineering in Agriculture; Vol. 20 No. 2 (2012); 163-174Revista Engenharia na Agricultura - REVENG; v. 20 n. 2 (2012); 163-1742175-68131414-398410.13083/reveng.v20i2reponame:Engenharia na Agriculturainstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/reveng/article/view/262/198silva, alexsandro oliveiraSilva, Ênio Farias de FrançaMoura, Geber Balrbosa de AlbuquerqueLopes, Pabricio Marcos oliveirainfo:eu-repo/semantics/openAccess2023-01-19T13:01:04Zoai:ojs.periodicos.ufv.br:article/262Revistahttps://periodicos.ufv.br/revengPUBhttps://periodicos.ufv.br/reveng/oairevistaengenharianagricultura@gmail.com||andrerosa@ufv.br||tramitacao.reveng@gmail.com|| reveng@ufv.br2175-68131414-3984opendoar:2023-01-19T13:01:04Engenharia na Agricultura - Universidade Federal de Viçosa (UFV)false |
