                         indices to the meteorological conditions in terms of temperature 
                         and precipitation conditions of the Amazon evergreen forest is 
                         arguably weaker than that of any other tropical continental 
                         region, despite the obvious connection. To assess such response, 
                         we have used different dataset of vegetation indices the 
                         Normalized Difference Vegetation Index (NDVI), Enhanced Vegetation 
                         Index (EVI) and Fraction of Vegetation Cover (FVC) derived from 
                         SPOT 4 Satellite VEGETATION data and Meteosat Second Generation 
                         (MSG) satellite products. Based on the covers time scales from 
                         daily to dekadal, at spatial resolutions from 1 to 3 km, and 
                         provides temporal coverage for the period of extremely El Niño 
                         event (between 1998-2000). And the weather data were compiled from 
                         the Large- Scale Biosphere-Atmosphere Experiment in Amazonia (LBA) 
                         HydroNet collection. The obtained results suggest that the 
                         combined effects of precipitation decrease and air temperature 
                         increase in the healthy Amazon evergreen forest is a possible 
                         explanation of the higher EVI values and the lower NDVI values 
                         during the dry season. On the other hand, FVC reflects the 
                         combined effects of precipitation and air temperature changes, 
                         shows the higher values for pasture and lower values during the 
                         wet season consistent with an increase in precipitation and a 
                         decrease in air temperature. Such distinct vegetation responses 
                         may be viewed as a function of the spatial scale.",
