             abstract = "Minas Gerais state, Brazil, has experienced severe water scarcity 
                         in some areas, demanding large-scale water balance studies to 
                         subsidize water policies. The reflectance bands from the MOD13Q1 
                         MODIS product were used together with agrometeorological data to 
                         acquire water balance indices in the state, during the years from 
                         2012 to 2015, later extracting the main agricultural growing 
                         regions, North, Northwest and Minas Triangle. Precipitation (Prec) 
                         and reference evapotranspiration (ET0) data from 36 weather 
                         stations were interpolated, while for the actual 
                         evapotranspiration (ET), the SAFER algorithm was used. A climatic 
                         water balance indicator was applied, the Water Balance Difference 
                         (WBd = Prec - ET) and, for the surface moisture, the 
                         evapotranspiration ratio (ETr = ET/ET0) was used. Higher WBd 
                         happened from the middle of October to the end of December, while 
                         the largest ETr values were between March and May.. According to 
                         the ETr values, the soil moisture storage showed a gap in relation 
                         to the WBd index, because the lapse time the soil to recover its 
                         retention capacity. Considering all studied years, ET attended the 
                         atmospheric demand by 50, 53 and 61% in ghe agricultural growing 
                         regions of North, Northwest and Minas Triangle. It was 
                         demonstrated the potential to monitor the water conditions for the 
                         16-day periods on a large scale by combining weather measurements 
                         and MODIS products.",
