SummaryThe proposed activity contributes to the scientific evaluation of TerraSAR-X data. It will address the theme Polar Research and cover also issues related to land cover and specifically hydrology. The focus will be on the Yamal peninsula underlain by permafrost. The study will focus on seasonal flooding in areas with permafrost thaw lakes which are expected to change with climate change. It will extent the work undertaken related to the archiveanalyses (LAN1706) and time series analyses already completed with ENVISATASAR wide swath mode. Especially the good temporal as well as spatialresolution which is available with the extented wide swath mode isexpected not only to extent previous records but also to yield newinformation (higher spatial resolution than ASAR WS) and thus providebetter insight into the studied phenomen. Analyses will include landcover classifications and change detection analyses. Wide swath mode will be used in combination with stripmap mode in order to address scaling issues. The stripmap mode usage is also important as extention to archive records to better separate seasonal and longterm changes. A transect which spans different landscape units as well as permafrost type is requested for the Wide swath acquistions. The stripmap mode area overalps with archive records and field sites of the project partners.
Planned deliverable is a joint publication.
Funding: The project COLD Yamal is funded by the Austrian Science Fund as well as the Russian Foundation for Basic Research (cold.zgis.net). It also ties into activities of the FP7 Project PAGE21 (AWI), the OEAW project ’Thaw lake dynamics’ (SPRI), ongoing high resolution satellite research of landslides (UEF).
