Abstract

The NOAA-AVHRR sensor has an interesting potential for drought monitoring in Mediterrenean environments. The combined use of meteorological and remote sensing indicators permits for the detection and for the follow-up of water stress in time and space. A comparative analysis between the satellite-based vegetation condition index (VCI) and the thermal condition index (TCI) on the one side and the standardized precipitation index (SPI) on the other side, allowed to demonstrate that NOAA-AVHRR images have a high potential as a diagnostic tool for drought monitoring and characterization.
