Continuous measurements of emissivity at 89 and 37 GHz frequencies were acquired in vertical and horizontal polarizations at fixed elevation angle of 55 degrees during transit and scanning elevation angles of 30-150 degrees at every station. The radiometers have been installed at the 200 level on the Amundsen icebreaker on the port side. Generally the instruments continued acquiring data at a fixed elevation angle during the transit, and 3-5 scans have been performed at every station along with auxiliary data such as GPS, geographic location of the station, photographs of the same field of view, air temperature, wind data, atmospheric conditions, surface characteristics, etc. The acquired data are in binary format which is produced for every scan and fixed mode. The time in the data logger is generally set to UTC. A filename example is 'RADDAT-2007-11-06-122647.DAT'.
