| Abstract: | This article elaborates on recent advances in the use of ScanSAR technologies for wetland-related research. The examples from boreal and subtropical environments are presented using the analysed ENVISAT ASAR Global mode the data acquired in 2005 and 2006. It is found that: 1) in the case of the ENVISAT ASAR instrument, data availability of the rather coarse Global Mode depends on request priorities of other competing modes, but acquisition frequency may still be on average fortnightly to monthly depending on latitude. 2) peatland types covering varying permafrost regimes of the West Siberian Lowlands can be distinguished from each other and other land cover by multi-temporal analyses. 3) the high seasonal and inter-annual dynamics of the subtropic Okavango Delta can also be captured by GM time series. 4) response to increased precipitation in 2006 differs from flood propagation patterns. 5) relative soil moisture maps may provide a valuable data source in order to account for external hydrological factors of such complex wetland ecosystems. |
