ESA Sea Ice Climate Change Initiative (Sea_Ice_cci) Sea Ice Concentration Climate Data Record from the AMSR-E and AMSR-2 Instruments at 25 km Grid Spacing, Version 1

The data set provides a 25 km grid Climate Data Record of Sea Ice Concentration (SIC) for the polar regions, derived from medium resolution passive microwave satellite data (AMSR-E and AMSR-2).本数据集提供了极地地区25千米网格的海冰浓度（Sea Ice Concentration，SIC）气候数据记录，其数据源自中分辨率被动微波卫星数据（AMSR-E与AMSR-2）。
