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'. This data set has been developed to study the microwave emissions coming off the sea ice, surface snow and sea water. The emissions can be used for various applications such as growth and melting of sea ice in different seasons. Depending on the turbulence in the ocean and the atmospheric boundary layer, the emissions will correspond to different turbulence conditions. Therefore, the turbulence in the boundary layer can be studied using these data. The microwave emissions depend upon the dielectric properties of the surface. Different ice types have different dielectric properties. Thus information on types of ice can be inferred from these data. This data is also collected at the same frequencies as used on the AMSR-E and AMSR-E 2 satellite-based sensors. Surface-based datasets can be used to validate the satellite-derived data.
