Description
Summary:Requirements for space based monitoring of permafrost features had been already defined within the IGOS Cryosphere Theme Report at the start of the IPY in 2007 (IGOS, 2007). The WMO Polar Space Task Group (PSTG, http://www.wmo.int/pages/prog/sat/pstg_en.php) identified the need to review the requirements for permafrost monitoring and to update these requirements in 2013.Relevant surveys with focus on satellite data are already available from the ESA DUE Permafrost User requirements survey (2009), the United States National Research Council (2014) and the ESA – CliC – IPA – GTN –P workshop in February 2014. These reports have been reviewed and specific needs discussed within the community and a white paper submitted to the WMO PSTG. Acquisition requirements for monitoring of especially terrain changes (incl. rock glaciers and coastal erosion) and lakes (extent, ice properties etc.) with respect to current satellite missions have been specified.About 50 locations ('cold spots') where permafrost (Arctic and ... : This dataset provides landscape units for the pan-Arctic which have been derived for upscaling purposes as part of the PAGE21 work package 5. Parameters relevant for geomorphological observations and carbon pools have been mostly selected from existing databases. The best dif-ferentiation of landscape units was obtained by using: Topographic Wetness Index, SAR backscatter, Land Surface Temperature (July and August), unfrozen period length, the slope steeper than 3°, Mean annual Surface Temperature, day first frozen, day first unfrozen and Land surface temperature Amplitude (July and August).This dataset comprises the landscape units as well as all input datasets (in case of applied post-processing of the original data source) in GeoTIFF format. ...
