卫星多通道被动微波传感器提供了全球辐射测量，用来绘制、监测和研究北极和南极极地海冰覆盖。这些数据跨越18年(截至1997年4月)，从1978年在NASA的海洋卫星A和Nimbus 7上发射扫描多通道微波辐射计(SMMR)开始，从1987年开始继续国防气象卫星计划(DMSP)特殊传感器微波/成像仪(SSMI)系列。预计DMSP SSMI系列将持续到21世纪。SSMI系列将增加新的、改进的传感器，用于日本和美国的太空平台。本用户指南介绍了一个新的海冰浓度数据集，该数据集是根据三个多通道传感器的观测结果生成的。该数据集包括1978年10月26日至1995年9月30日期间北极和南极地区的格网日冰密度(SMMR数据每隔一天一次)，但1987年12月3日至1988年1月12日的6周数据缺口除外。这些数据放在两张光盘上，其中包括一份ReadMeCD文件，其中提供了关于光盘的文件格式、文件头、北极和南极网格、辅助数据集和目录结构的技术细节。光盘将由位于科罗拉多州博尔德市的国家冰雪数据中心分发。
Satellite multichannel passive-microwave sensors have provided global radiance measurements with which to map, monitor, and study the Arctic and Antarctic polar sea ice covers. The data span over 18 years (as of April 1997), starting with the launch of the Scanning Multichannel Microwave Radiometer (SMMR) on NASA's SeaSat A and Nimbus 7 in 1978 and continuing with the Defense Meteorological Satellite Program (DMSP) Special Sensor Microwave/Imager (SSMI) series beginning in 1987. It is anticipated that the DMSP SSMI series will continue into the 21st century. The SSMI series will be augmented by new, improved sensors to be flown on Japanese and U.S. space platforms. This User's Guide provides a description of a new sea ice concentration data set generated from observations made by three of these multichannel sensors. The data set includes gridded daily ice concentrations (every-other-day for the SMMR data) for both the north and south polar regions from October 26, 1978 through September 30, 1995, with the one exception of a 6-week data gap from December 3, 1987 through January 12, 1988. The data have been placed on two CD-ROMs that include a ReadMeCD file giving the technical details on the file format, file headers, north and south polar grids, ancillary data sets, and directory structure of the CD-ROM. The CD-ROMS will be distributed by the National Snow and Ice Data Center in Boulder, CO.
