K10 Global 10km Analyzed SST data set for 2016-05-17 (NCEI Accession 0153622)

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.

本数据集为高分辨率海表温度工作组（GHRSST）四级海表温度分析产品，由美国海军海洋学办公室（NAVOCEANO）以业务化流程每日生产，采用全球0.1度网格。该K10型四级海表温度分析产品的观测数据源包括甚高分辨率辐射计（AVHRR）、地球观测系统高级微波扫描辐射计（AMSR-E）以及地球静止业务环境卫星（GOES）成像仪。在加权平均计算过程中，会综合考量数据的时效性、可靠性与分辨率，并对分析结果进行校准，以表征1米深度的海表温度。若34天后无新增卫星海表温度反演产品可用，则采用AVHRR Pathfinder 9公里气候态数据集。
