“…This method behaves best for weekly or longer predictions, although some accurate ETo daily estimations have been reported in the literature (Hargreaves & Allen, 2003). Barros et al (2009) Similar to the present work, Jabloun & Sahli (2008) verified that the FAO-PM model using only maximum and minimum temperatures in general provided satisfactorily good ETo estimates compared to FAO-PM in various locations in Tunisia. Considering all locations, the R 2 values were greater than 0.9 and the slope values ranged from 0.96 to 1.06, showing strong relation between ETo-Tmax, Tmin and FAO-PM.…”

“…By contrast, over a three month period the analysis indicated that the period July-September was better adjusted with linear regression (R 2 = 0.8415), Table 2 and Figure 4. However the results presented here were not as good as those presented by Jabloun & Sahli (2008) Table 2 that both accuracy, given by the trend line, and precision demonstrated by the dispersion of the data around the fitted 1:1 line or Willmott index, were reasonable in this study. Otherwise, the confidence index shows that the models are very good and good for general analysis and for three-month periods, which are more recommended for its application.…”

“…Em regiões de clima semiárido, onde os recursos hídricos são limitados e seriamente ameaçados pela excessiva exploração, é essencial a estimativa das necessidades hídricas com maior precisão (JABLOUN;SAHLI, 2008). A baixa pluviosidade, altas temperaturas e altas taxas de evaporação podem representar dificuldades para os pequenos agricultores das zonas rurais do Nordeste do Brasil (ANDRADE et al, 2011).…”

“…Procedimentos para validação do método de Penman-Monteith FAO para o cálculo da ET o com dados limitados têm sido empregado em diferentes países e condições climáticas, como: Bulgária (POPOVA et al, 2006); China (CAI et al, 2007); Tunísia (JABLOUN;SAHLI, 2008); Servia (GOCIC; TRAJKOVIC, 2010) e Canadá (SENTELHAS et al, 2010). No Brasil, o cálculo da ET o com dados limitados foi empregado no estado de Minas Gerais (LIMA, 2005) e Ceará (SILVA et al, 2010;ROCHA et al, 2011).…”
