DUE Permafrost Project Consortium (2012): ESA Data User Element (DUE) Permafrost: Circumpolar Remote Sensing Service for Permafrost - Local Services-I: terrain elevation and terrain subsidence - with links to datasets [dataset bibliography]. PANGAEA, https://doi.org/10.1594/PANGAEA.783634

The main purpose of the ESA Data User Element (DUE) Permafrost project (2009-2012) was to define, demonstrate, and validate a permafrost monitoring information service based on operational satellite data that are processed for the pan-permafrost region North of 55° N.

DUE Permafrost uses a suite of indicative remote sensing-derived parameters: 'Land Surface Temperature' (LST), 'Surface Soil Moisture' (SSM), 'Surface Frozen/Thawed State' (Freeze/Thaw), 'Elevation', 'Land Cover' (LC), and 'Surface Waters'. The remote sensing data products are provided from local to large spatial scales.

The DUE Permafrost consortium has been led by the Vienna University of Technology, Austria being responsible for all parameters based on microwave remote-sensing technology (active and passive microwave sensors): Surface Soil Moisture (SSM) with weekly to monthly averages from 2007 to 2010, Freeze/Thaw and Surface Waters.

The University of Waterloo (Canada) provided Land Surface Temperature Services (LST) from MODIS and ENVISAT-AATSR with weekly to monthly averages from 2000 to 2010 (varying by sensor and region).

The Friedrich Schiller University (Germany) is responsible for the circum-Arctic/ boreal Land Cover products including local high resolution information and burned areas.

Gamma Remote Sensing (GAMMA, Switzerland) assembled national DEM data-sets and build-up the first circum-arctic DEM dataset with a 100 m pixel resolution north of 55° N.

The Alfred Wegener Institute for Polar and Marine Research (AWI, Germany) organized the exchange between the scientific stakeholders of the permafrost community and the project consortium, including the managing of the ground data used for the evaluation of products.

The first version of the full dataset has been released in the beginning of 2011, the final version in March 2012. The Full Product Set (FPS) with Circum-Arctic and Regional products is published doi:10.1594/PANGAEA.780111.

I) ALOS-Prism Digital Elevation models (spatial resolution 10 m) for three local sites: central Yakutia (Russia), Polar Bear Pass (Canada) and central Yamal peninsula (Russia, Ob service case region). (Vienna University of Technology).

II) The main result of the SAR interferometric analysis is a temporal series of displacement maps on coherent targets in the satellite line-of-sight direction. Local InSAR Digital Elevation models are provided for two regions, Alaska Northslope (US) and Mackenzie River Delta (Canada): ASAR InSAR DEM, North Slope (Alaska); Terra SAR-X InSAR DEM North Slope (Alaska); Terra SAR-X InSAR DEM, Mackenzie River Delta (Canada).
