Mission Report (Michael Studinger, Mission Scientist)

The primary candidate mission for today was a sea ice mission (Connor Corridor) underflying the SARAL spacecraft, which uses the same orbit as Envisat and operates a Ka-band (35.75 GHz) radar altimeter called AltiKa. The plan was to fly the same line out and back, flying the out leg at the normal 1,500' altitude, and the return leg at ~15,000'. The orbit geometry today was suitable for the mission, however, a well-established low pressure system with bad weather prevented us from flying the mission (Fig. 2) and instead we selected a land ice mission. As expected we were barely able to stay below the mid-level clouds of this system over Ellesmere Island.

The "South Canada Glaciers" mission was a combination of centerlines and fluxgates for the major outlet glaciers of the Prince of Wales and southern Agassiz ice caps, as well as for Belcher Glacier on the Devon ice cap. We flew centerlines for the most part, and we added a few fluxgates for glaciers whose centerlines we did not fly, and for the unusually wide Cadogan, Trinity and Wykeham glaciers. We also flew a total of three flowlines on the Trinity and Wykeham glaciers, and we flew two flowlines on the Belcher Glacier. The centerlines and fluxgates were designed by Dave Burgess and Martin Sharp and the flight hours of today's flight are charge to Flight Request 14P009 in support for the CSA/NASA agreement. The MCoRDS radar was be operated in tomographic mode for the entirety of this mission. Aircraft altitude was maintained at 3000-3500' AGL as best as possible in order to achieve wide-swath tomography over the glaciers.

 LiDAR data collection started 05/06/2014 11:42 UTC and ended at 16:57 UTC. In total we collected 5.3 hours of science data and we able to stay below the mid-level clouds during the entire time in the survey area (Fig. 2).
