Surface-based Passive Microwave Brightness Temperatures - Canadian Arctic during the 2009 ArcticNet / Industrial Partnership Field Study

Continuous measurements of emissivity at 89 and 37 GHz frequencies in vertical and horizontal polarizations at a fixed elevation angle of 55 degrees during transit and scanning elevation angles of 30-150 degrees at every station were acquired. The radiometers were installed at the 200 level on the CCGS Amundsen icebreaker on the port side. Generally the instruments acquired data at the fixed elevation angle during transit, and 3-5 scans were performed at every station along with auxiliary data collection (GPS data, 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 modes. The time in the data logger is generally set to UTC. An example filename would be 'RADDAT-2007-11-06-122647.DAT'.
