资源简介：
The Visible Infrared Imager Radiometer Suite (VIIRS) Sea Ice Extent 6-Min L2 Swath 375m is Near Real Time(NRT) (short name VNP29_NRT) data set reports the location of sea ice cover derived from radiance data acquired by VIIRS. Following the approach used by MODIS, the algorithm assumes that sea ice is snow covered and can be detected using the Normalized Difference Snow Index (NDSI). The VIIRS instrument flies on board the Suomi National Polar-orbiting Partnership (S-NPP) satellite.

本数据集为可见光红外成像仪辐射计套装（VIIRS）海冰范围6分钟L2条带375米近实时（NRT）数据集（简称VNP29_NRT），报告了由VIIRS获取的辐射数据所推导出的海冰覆盖位置。继MODIS方法之后，算法假定海冰被积雪覆盖，且可利用归一化差异积雪指数（NDSI）进行检测。VIIRS仪器搭载于苏omi国家极地轨道合作伙伴（S-NPP）卫星上。欲了解更多信息，请参阅产品用户指南：
