Abstract

SPOT-Vegetation (SPOT-VGT) data at full spatial resolution were used in order to assess the potentiality and feasibility of using low resolution optical satellite data for the estimation of time/space dynamics of surface moisture content. The seasonal trend of diverse parameters (single channels or spectral indices) suitable/or specifically designed for moisture estimation have been analyzed in some test sites of southern Italy. The investigations were performed by using imagery selected from a long time series of ten-day compositions of VGT data acquired from 1998 to 2002. The preliminary results indicate that the use of the VGT data for obtaining information on the time/space dynamics of surface moisture content can be useful.
