| Summary: | This presentation reviews achievements with C-band SAR in generaland specifically Sentinel-1 for Arctic land monitoring, theimplications of the current acquisition strategy including theavailability of certain polarizations and discusses differencesto other wavelengths through the use of Kennaugh parameterization.Unfrozen as well as frozen season observationsprovide added value. C-VV has the best availability and canbe used for a wide range of land cover and terrain changestudies. C-HH has been proven applicable for soil characterizationbut can only be applied regionally. A combinationwith other wavelengths (demonstrated for X-band) is promisingfor specifically mapping of wetlands, which are of interestwith respect to permafrost applications.
