                         MODIS product with one calculated from Landsat ETM+ sensor for the 
                         Serra da Mantiqueira Region. An empirical algorithm was applied to 
                         estimate surface albedo with ETM+ data. The results shows that 
                         there is agreement among MODIS surface albedo product and the one 
                         obtained with ETM+ data (Rē = 0.64) at the confidence level of 
                         99%. Albedo values ranged between 0 and 0,2 in MODIS product with 
                         average of 0.16 and between 0 and 0,33 with average of 0,25 in the 
                         ETM+ derived map. The main sources of uncertainty that are 
                         responsible for the different albedo intervals were the difference 
                         in the surface moisture between the days that preceded the ETM+ 
                         acquisition and the integration time of the MODIS product and the 
                         differences in spatial resolution of the MODIS sensors (1 km) and 
                         the ETM+ (30 m).",
