abstract = "Maximum NDVI composites of NOAA-AVHRR GAC data and monthly
precipitation records from the ground network of weather stations
(August 1981 to January 1985)of vegetation covers of the Amazonia
region were analyzed to verify the relationship between NDVI and
precipitation at different climatic/vegatation classes selected.
NDVI mean values for Dense Forest was 0,452, for Open Forest
0,422, for {"}Cerrado {"} 0,417, and for Transition Forest 0,390.
The amplitude of the means of these NDVI associated with the
seasonal effect of climate on the vegetation cover varied about
39. Although a quantitative relationship between NDVI and
precipitation was not significant, NDVI values seem to follow the
seasonal variation in precipitation with some lag depending on the
vegetation type. Several weather anomalies, such as the El Nino
event of 82/83 is reflected in both NDVI and precipitation data
sets.",
