    Project Details


    Wind erosion is a major source of soil degradation in arid and semiarid areas. Dust and sand storms eroding agricultural areas are of major economic importance globally, and desertification is a main issue of global change studies.
    An allocation of 80 ERS scenes is obtained, through a third Announcement of Opportunity (AO3) for the exploitation of ERS data from ESA.
    In this study ERS InSAR techniques will be tested in four semi-arid areas (Israel/Nizzana, USA/Salton Sea, Egypt/Western Gulf of Suez, and Burkina Faso/Oudalan Province). In previous ERS studies interferometric phase images was used to derive Digital Elevation Models which were then investigated with respect to change. In this study we shall also use correlation images in an attempt to estimate the components of the sediment budget and changes of the vegetation cover. We will relate the results to other possible techniques, in-situ or other remote sensors.
