nLw671, NOAA S-NPP VIIRS, Science Quality, Global 4km, Level 3, 2012-present, Monthly

Level-3 Standard Mapped Image (SMI), Global, 4km, nLw671, Monthly 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.

三级标准映射图像（SMI），全球覆盖，4公里分辨率，nLw671波段，月度合成数据，源自可见光和红外成像仪/辐射计套件（VIIRS）。这些数据具有科学质量，具有15天的延迟。NOAA/STAR海洋颜色小组处理的数据基于MSL12 v1.2版本，并使用OC-SDR v04进行处理，自2017年8月7日起由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的后继产品。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运行环境卫星系统。JPSS是NOAA及其采购代理NASA之间的合作项目。
