Global Sea Ice Concentration (netCDF) - DMSP

Daily averaged fractional ice cover in percentage, processed from passive microwave satellite data (SSMIS) over the polar regions. Sea ice concentration and its uncertainties are calculated from swath observations, and averaged and gridded to the daily fields. Better than using this archived NRT sea ice concentration product, please use the reprocessed sea ice concentration data record v2.0 (EO:EUM:DAT:MULT:OSI-450).

本数据集为基于极地地区被动微波卫星数据（SSMIS）处理得到的日平均百分比海冰覆盖占比。研究人员从条带观测数据中计算得到海冰浓度及其不确定性，经平均处理与格点化后生成日尺度格点场数据。相较于本存档近实时海冰浓度产品，更推荐使用再处理版海冰浓度数据记录v2.0（EO:EUM:DAT:MULT:OSI-450）。
