Soil moisture mapping in a semi-arid region, based on ASAR/Wide Swath satellite data
Résumé
In this paper, an operational algorithm is proposed for the mapping of surface moisture over a site in North Africa. A change detection approach is applied, using 160 Envisat ASAR Wide Swath images acquired over a 7-year period. Parameterization of this algorithm is considered for three classes of vegetation cover density (NDVI
