Table 1.
Statistic performance of ETo methods in daily scale in relation to the Penman-Monteith method, considering the Accuracy (mean absolute percentage error, Mape), Precision (R2), Tendency (systematic error, SE). Tukey´s test with significant minimum difference (DMS) at level of 5% probability for annual (AN), summer (SU), autumn (AU), winter (WI) and spring (SP) analysis.
