MEaSUREs Arctic Sea Ice Characterization Daily 25km EASE-Grid 2.0, Version 1

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 includethe 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（NASA）面向研究环境使用的地球系统数据记录制作（Making Earth System Data Records for Use in Research Environments, MEaSUREs）计划，提供1979年至2012年北极海冰特性的逐日记录，数据源自被动微波亮度温度反演结果。其涵盖的海冰特性包括海冰覆盖位置、海冰年龄、融冰起始日以及融冰起始状态。数据采用25 km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，并以网络通用数据格式（netCDF）文件形式提供。
