Alex Coccia from MetaSensing sends us the next blog post from Antarctica. He is part of the team contributing to ESA’s CryoVEx/KAREN campaign, which is an international effort to develop new space technology to monitor the polar regions.
When the weather doesn’t allow for airborne operations, there is always a plan B. Alex Coccia (Metasensing), Arne Olesen (DTU) and David Landy (BAS) having a cup tea in the desert… of snow. (Metasensing)
Team members from the Danish University of Technology and our company, Metasensing, have been in Antarctica since Christmas. We have been taking measurements of the ice and snow with Ku-band and Ka-band radar altimeters, a lidar, and inertial and geodetic units that are carried on a Twin Otter aircraft from the British Antarctic Survey.
The belly of the aircraft with remote sensing instruments: a lidar and the two radar altimeters, one that uses Ka-band (KAREN) and one that uses Ku-band (ASIRAS). (Metasensing)
The point of the campaign is to investigate how a two-wavelength radar altimeter could offer continuity and improve the current single-wavelength measurements provided by ESA’s CryoSat mission.
CryoSat uses a Ku-band radar altimeter, but Ka-band penetrates the snow less and could, therefore, provide useful complementary information ...
