Titre : Synthesis of change detection parameters into a land-surface change indicator for long-term desertification studies

Code du projet : ENV4970683 FP4-ENV 2C

Durée : From 1998-04-01 to 1999-08-31

Descriptif
The RESYSMED project buildson previous achievements in the production of calibrated, georeferenced, normalized and corrected series of METEOSAT, NOAA-AVHRR, LANDSAT-TM, SMMR, SSM/I, and ERS 1-2 SAR and WSC data. From the measurements with these sensors specific "primary" land-surface parameters are derived. These "primary" data sets are used for diagnostic purposes to quantify changes at the landsurfaces in semi arid regions. Combined with models they serve the production of more complex information, such as fluxes and soil moisture. The goal of the project is to merge these different information of the land-surface into a "land-surface change indicator" (LCI) that is applied to quantify the state of surface and - in combination with longe term data series - to analyse the process of desertification. _ A three pronged strategy is followed in the project, on the basis of the results of the previous ENV4-CT95-0094 : Firstly, the production and evaluation of normalized large scale and longer term "primary" data sets that more or less can be inferred directly from measurements made in space and used as indices for changes that occur at the land surface. Secondly, the "upgrading" of these indices to process advanced quantities like fluxes (radiation, heat) or soil moisture changes, by combining the primary data with models. Thirdly, the application of these combinations of satellite data and models at limited areas where a validation of the information deduced from the spaceborne measurements can be performed by comparing them with collateral higher resolution remote sensing data or measurements made at specific sites at the surface.
