                         Plateau and widely and heterogeneously spread along a variety of 
                         latitudes, longitudes and altitudes, is the richest savanna in the 
                         world and a major contributor to some of the largest and most 
                         important watershed basins in South America. On the other hand, 
                         the Cerrado is the most severely threatened biome in Brazil, with 
                         more than 40% of its original area already converted to 
                         agricultural crops and cultivated pastures. In this study, which 
                         is part of a larger effort aiming at the monitoring of the Cerrado 
                         vegetative cover, we evaluated the effective availability of 
                         moderate spatial resolution remote sensing data for the 2001 - 
                         2007 period. The analysis of the 16 day composited MOD13Q1 
                         (vegetation indices) product indicated that only data from April 
                         to September is capable of covering more than 80% of the biome 
                         remnant vegetation. Depending on the frequency at which the biome 
                         is to be monitored, alternatives to this critical data gap may 
                         include spatial and temporal interpolation (e.g. via algorithms 
                         like Timesat or frequency domain transformations), as well as the 
                         combined use of optical and SAR imagery.",
