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 VJ129_NRT) product 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 NOAA-20 - formerly the Joint Polar Satellite System-1 (JPSS-1) satellite.

可见光红外成像仪辐射计套件（VIIRS）海冰范围6分钟L2条带375米近实时（NRT）产品（简称VJ129_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所采用的方法之后，该算法假定海冰被积雪覆盖，并可利用归一化差异积雪指数（NDSI）进行检测。VIIRS仪器搭载于NOAA-20卫星上，该卫星曾名为联合极地卫星系统-1（JPSS-1）。欲获取更多信息，请参阅产品用户指南：https://viirsland.gsfc.nasa.gov/PDF/VIIRS%20C2%20Sea%20Ice%20Cover%20Pr…以及产品算法理论依据文件（ATBD）：https://viirsland.gsfc.nasa.gov/PDF/VIIRS_SeaIceCover_ATBD_V2.pdf
