Helicopter-borne passive-microwave observations during the SIPEX II voyage of the Aurora Australis, 2012

This dataset contains sea ice surface brightness temperatures using a portable passive-microwave radiometer operating at 36Ghz-H,V mounted to the undercarriage of a Squirrel helicopter during SIPEX 2, 2012.This radiometer is the same sensor as satellite passive-microwave radiometer AMSR-E and AMSR2.Our passive-microwave radiometer is launched on the same helicopter as Jan Lieser's (RAPPAL), so please see the "SIPEX-2 RAPPLS Surveys (Radar, Aerial Photography, Pyrometer, and Laser Scanning system)" metadata file for details of the aircraft. The RAPPLS dataset also contains track (GPS position) and altitude data, which can be used in conjunction with this dataset.The CSV files in this dataset are the raw files as output by the sensor. These raw data files show only the relevant parameters (time and brightness temperatures).
