This study evaluated the changes occurring in the NEB through the time-space analysis of albedo, NDVI and Ts obtained with MODIS data in the period from 2002 to 2011. The data collected by remote sensing were associated with precipitation data obtained by reanalysis to evaluate the areas of interest and their respectivCensoe selected sample points. The albedo presented more than 75% of its data in the range of 0.10 to 0.20 and Ts values were higher than 28 °C in 88% of the points. The NDVI and precipitation analyze indicated that 73% and 76% of the data were higher than 0.50 and 1900 mm/year, respectively. Significant increases in Ts were observed in years that more than 75% of precipitation data were below 1500 mm/year and NDVI growth associated with years of precipitation increase. The Mann-Kendall test at the 5% level pointed to the occurrence of significant trends only for the targets in the caatinga and cerrado areas. The highest values of NDVI were in areas of humid tropical climate and equatorial climate, with values above 0.70.
