  1. Data referred to the reported reference meteorological station and climatic classification from Ininda et al. (2007). Tx, Tn, Td = maximum, minimum and mean temperature; Dtr = daily thermal range; Ev = Evaporation; Rh = Relative humidity; Sr = Solar radiation; Sh = sunshine duration; Wt = wind totalized. Tx, Tn, Td, Dtr and Rr are from 1983-2009 data (NOAA, 2010). Data from FAO Climwat database[54] are highlighted with the asterisks.
