IceSAR campaign heads north

From Klaus Scipal (ESA), Greenland, 7 June As part of the IceSAR 2012 campaign, Jørgen Dall and Anders Kusk from DTU and I headed up north yesterday to fly the Polaris system over the K-transect on Russell Glacier in southwest Greenland. This is near Kangerlussuaq, 67° N, just inside the Arctic Circle. The campaign supports the evaluation of the Biomass candidate Earth Explorer mission. It may sound a little strange that a mission designed to measure forests properties in the Tropics will also be used to map glaciers and ice sheets. This is thanks to the unique Biomass instrument and mission concept, which is based on using a very long wavelength (P-band)...

IceSAR: April flights

From Jørgen Dall and Anders Kusk (DTU Space), Kangerlussuaq, 22 April From Thursday to Saturday (19–21 April), a Twin Otter aircraft was flown over the K-transect, a line starting at the Russell outlet glacier near Kangerlussuaq and stretching some 150 km into the ice sheet. The Twin Otter carried a radar called POLARIS, developed for ESA by the Technical University of Denmark. Asa Tania’s earlier post mentioned, the objective was to assess one of the secondary objectives of ESA’s Biomass Earth Explorer candidate mission: ice mapping. The direction of the antenna pattern can be steered by means of electronic beamforming, and looked to the left, to the right and straight down with...
