K10 Global 10km Analyzed SST data set for 2016-09-20 (NCEI Accession 0158164)

A Group for High Resolution Sea Surface Temperature (GHRSST) Level 4 sea surface temperature analysis produced daily on an operational basis at the Naval Oceanographic Office (NAVOCEANO) on a global 0.1 degree grid. The K10 L4 sea surface temperature analysis uses SST observations from the Advanced Very High Resolution Radiometer (AVHRR), the Advanced Microwave Scanning Radiometer for EOS (AMSR-E), and the Geostationary Operational Environmental Satellite (GOES) Imager. The age, reliability, and resolution of the data are used in the weighted average with the analysis tuned to represent SST at 1 meter depth. AVHRR Pathfinder 9km climatology is used when no new satellite SST retrievals are available after 34 days.

高分辨率海表温度工作组（Group for High Resolution Sea Surface Temperature，GHRSST）四级海表温度（Sea Surface Temperature，SST）分析产品，由美国海军海洋学办公室（Naval Oceanographic Office，NAVOCEANO）以业务化模式每日产出，采用全球0.1度网格。K10 L4级海表温度分析产品使用了甚高分辨率辐射计（Advanced Very High Resolution Radiometer，AVHRR）、地球观测系统先进微波扫描辐射计（Advanced Microwave Scanning Radiometer for EOS，AMSR-E）以及地球静止业务环境卫星（Geostationary Operational Environmental Satellite，GOES）成像仪获取的海表温度观测数据。该分析过程中，会将数据的时效、可靠性与分辨率纳入加权平均计算，并对分析结果进行校准，以表征1米深度的海表温度。若34天后无新的卫星海表温度反演数据可用，则采用AVHRR Pathfinder 9公里气候态数据集。
