“…The adjustment of estimation of ETo for methods MK in comparison to PM is less efficient than HG and RS. Similar results found by PILAU et al (2012), in Frederico Westphalen and Palmeira das Missões in Rio Grande do Sul, where the method MK underestimated ETo in relation to PM used as standard in most of the months of the year. For the region of Araraquara -SP, VESCOVE & TURCO (2005), comparing estimation methods of ETo , observed that method Makkink underestimated ETo in relation to PM during winter-spring, more substantially than in the period summer-autumn.…”

“…Studies comparing estimation methods of ETo in relation to method of Penman-Monteith parameterized by FAO are performed for different regions in Brazil and worldwide, as a way to evaluate efficiency of indirect methods (VESCOVE & TURCO, 2005;GAVILÁN et al, 2007;REIS et al, 2007;PEREIRA et al, 2009;TAGLIAFERRE et al, 2010;FRANÇA NETO et al, 2011;CAVALCANTE JÚNIOR et al, 2011;ALENCAR et al, 2011;PILAU et al, 2012;BORGES JÚNIOR et al, 2012). The results of conducted research varied extremely, since each region present peculiar climate characteristics and the estimation methods of ETo exhibits problems of precision and accuracy, mainly because of the non-adjustment of model coefficients and sensors accuracy (BARROS et al, 2009).…”

“…Among all methods studied in this research, the equations Thornthwaite-Modified along with Thornthwaite, which received "not good" performance, are the only physical equations. Some researchers have found good performance in these methods in Brazil (BACK, 2008;SILVA et al, 2011;PILAU et al, 2012), except ARAÚJO et al (2012) for the Thornthwaite method in the State of Roraima, Brazil.…”

“…A precisão foi avaliada pelo coeficiente de correlação (r) que indica o grau de dispersão dos dados obtidos em relação à média (BORGES JÚNIOR et al, 2012;PILAU et al, 2012), ou seja, o erro aleatório, o qual é determinado pela expressão: (14) em que: x i são os valores a serem comparados com o método-padrão; são os valores estimados pelo método-padrão e e são as médias respectivas de e .…”

“…A exatidão foi determinada pelo índice de Willmott (d), segundo metodologia apresentada por Camargo e Sentelhas (BORGES JÚNIOR et al, 2012;PILAU et al, 2012) (2012), constata-se a importância de trabalhos regionalizados deste gênero, para validar métodos alternativos ao de Penman-Monteith para a determinação da ETo aplicados ao cálculo do IS. Na Figura 5, está representado o erro-padrão aplicado ao índice de seca (EPE_IS, mm m -1 ), para o período de outubro a março e para o mês de março.…”
