Abstract

In June 1992 the ASMODE-project was started on the assessment of remote sensing techniques for the monitoring of the extent and progression of desertification in the Mediterranean area. Data of several satellite-sensors (NOAA-AVHRR, METEOSAT and LANDSAT) are researched on their usefulness for the monitoring of desertification. Two approaches to monitor desertification are followed in the ASMODE-project: (1) The energy and water balance approach to monitor vegetation activity. Satellite measured land surface temperatures and albedo's are used to estimate aridity parameters like net radiation, actual evapotranspiration, and rainfall. (2) The direct monitoring of the vegetation cover using the vegetation index. The project consists of a one-year monitoring experiment generating satellite derived datasets of Spain to be analyzed in connection with field survey data and existing datasets in a GIS. KNMI was responsible for the `NOAA-AVHRR' part of the project. In this paper the methodology used by KNMI and final NOAA-AVHRR results are presented.
