nLw486, NOAA S-NPP VIIRS, Science Quality, Global 4km, Level 3, 2012-present, Weekly, Lon0360

Level-3 Standard Mapped Image (SMI), Global, 4km, nLw486, Weekly composite data from the Visible and Infrared Imager/Radiometer Suite (VIIRS). These are science quality data with a 15-day latency. The data, processed by the NOAA/STAR Ocean Color Team, are produced from MSL12 v1.2 using OC-SDR v04 and were release by CoastWatch as of 2017-08-07. VIIRS is a multi-disciplinary instrument that flies on the Suomi-NPP (National Polar-orbiting Partnership) satellite and is the successor to MODIS. Suomi-NPP is the initial spacecraft in the JPSS (Joint Polar Satellite Systems) series of spacecraft. JPSS is our Nation's next generation polar-orbiting operational environmental satellite system. JPSS is a collaborative program between NOAA and its acquisition agent NASA.

第三级标准映射图像（SMI），全球范围，4公里分辨率，nLw486，由可见光和红外成像仪/辐射计组件（VIIRS）生成的每周综合数据。这些数据具有科学质量，存在15天的延迟。数据由NOAA/STAR海洋颜色小组处理，采用MSL12 v1.2版本，使用OC-SDR v04软件生成，并于2017年8月7日由CoastWatch发布。VIIRS是一种多学科仪器，搭载于Suomi-NPP（国家极地轨道伙伴计划）卫星上，是MODIS的继任者。Suomi-NPP是JPSS（联合极地卫星系统）系列航天器的首颗航天器。JPSS代表我国下一代极地轨道业务环境卫星系统。JPSS是NOAA与其采购代理NASA之间的合作项目。
