OSTIA L4 SST Analysis for 2016-09-22 (NCEI Accession 0158148)

A Group for High Resolution Sea Surface Temperature (GHRSST) Level 4 sea surface temperature analysis produced daily on an operational basis at the UK Met Office using optimal interpolation (OI) on a global 0.054 degree grid. The Operational Sea Surface Temperature and Sea Ice Analysis (OSTIA) analysis uses satellite data from sensors that include the Advanced Very High Resolution Radiometer (AVHRR), the Advanced Along Track Scanning Radiometer (AATSR), the Spinning Enhanced Visible and Infrared Imager (SEVIRI), the Advanced Microwave Scanning Radiometer-EOS (AMSRE), the Tropical Rainfall Measuring Mission Microwave Imager (TMI), and in situ data from drifting and moored buoys. This analysis has a highly smoothed SST field and was specifically produced to support SST data assimilation into Numerical Weather Prediction (NWP) models.

本数据集为高分辨率海表温度工作组（Group for High Resolution Sea Surface Temperature, GHRSST）4级海表温度分析产品，由英国气象局（UK Met Office）每日以业务化运行模式生成，采用最优插值（optimal interpolation, OI）方法，在全球0.054度分辨率网格上开展计算。
业务化海表温度与海冰分析（Operational Sea Surface Temperature and Sea Ice Analysis, OSTIA）所使用的卫星数据来源包括先进甚高分辨率辐射计（Advanced Very High Resolution Radiometer, AVHRR）、先进沿轨扫描辐射计（Advanced Along Track Scanning Radiometer, AATSR）、旋转增强型可见红外成像仪（Spinning Enhanced Visible and Infrared Imager, SEVIRI）、先进微波扫描辐射计-地球观测系统（Advanced Microwave Scanning Radiometer-EOS, AMSRE）以及热带降雨测量任务微波辐射计（Tropical Rainfall Measuring Mission Microwave Imager, TMI），同时整合了漂流浮标与锚定浮标的原位观测数据。
该分析生成的海表温度场高度平滑，专为支持将海表温度（Sea Surface Temperature, SST）数据同化至数值天气预报（Numerical Weather Prediction, NWP）模型而研发。
