This report examines notable atmospheric and cryospheric conditions observed by satellites over the Beaufort Sea region surrounding the Leadex ice camp position. DMSP and NOAA direct readout high resolution data include visible and infrared scenes in a variety of discrete channels. The special sensor microwave imager (SSM/I) data of DMSP and the synthetic aperture radar (SAR) data of the European ERS-1 satellite are of special interest and value in evaluating changes in ice appearance and configuration noted during the period of Leadex from 25 March to 24 April 1992. Multi-channel comparisons of the various data types over the same location and correlation with available ground truth data yield significant insights into the nature and state of the phenomena observed.
