This data set, part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) program, provides a daily record of Arctic sea ice characteristics for the years 1979 through 2012 derived from passive microwave brightness temperatures. Characteristics include the location of sea ice cover, sea ice age, day of melt onset, and status of melt onset. Data are gridded in the 25 km Equal-Area Scalable Earth Grid (EASE-Grid) 2.0 and provided as netCDF files....本数据集隶属于美国国家航空航天局（National Aeronautics and Space Administration, NASA）地球系统数据记录科研环境应用计划（Making Earth System Data Records for Use in Research Environments, MEaSUREs），提供了1979年至2012年北极海冰特性的逐日记录，数据基于被动微波亮度温度反演得到。所涵盖的海冰特性包括海冰覆盖范围、海冰冰龄、融冰起始日期以及融冰起始状态。数据以25公里分辨率的等面积可缩放地球网格（Equal-Area Scalable Earth Grid, EASE-Grid）2.0进行网格化存储，并以netCDF格式文件提供。
