Abstract

In order to accurately assess the occurrence, extent and severity of a drought it is necessary to get a correct picture of the spatial and temporal distribution of a number of meteorological, hydrological and surface variables. Space observations have the potential to make a significant contribution in this field. Due to the capability to retrieve surface parameters with high spatial and temporal resolutions over large areas, a comprehensive view of the situation can be obtained. The satellite sensor measures, however, radiation fields and the conversion of these measurements into surface parameters and further into information regarding drought conditions needs sophisticated analysis tools.

This paper reviews current possibilities to use remote sensing data for drought detection and monitoring and indicates near-future developments. Examples are given for the Mediterranean regions of Andalusia in southern Spain and Sicily in southern Italy.
