Abstract

Soil moisture is an import parameter for high latitude research focusing on carbon exchange and permafrost issues. This paper reviews requirements, constrains and possibilities of satellite derived soil moisture data for high latitude applications. Major points are freezing and thawing, and landscape heterogeneity. Special focus is on data derived from ENVISAT ASAR. The different ScanSAR modes (wide swath and global monitoring mode) can be used to address various issues. Sensitivity over tundra at this wavelength is similar to semi-arid regions in mediterranean and subtropic climates.
