OSTIA L4 SST Analysis for 2016-09-23 (NCEI Accession 0158141)

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.

高分辨率海表温度工作组（Group for High Resolution Sea Surface Temperature, GHRSST）旗下的四级海表温度分析产品，由英国气象局（UK Met Office）以业务化模式每日生成，采用最优插值（optimal interpolation, OI）方法，基于全球0.054度网格构建数据集。该业务化海表温度与海冰分析产品（Operational Sea Surface Temperature and Sea Ice Analysis, OSTIA）所使用的数据，涵盖以下传感器的卫星观测资料：先进甚高分辨率辐射计（Advanced Very High Resolution Radiometer, AVHRR）、先进沿迹扫描辐射计（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）、热带降雨测量任务微波成像仪（Tropical Rainfall Measuring Mission Microwave Imager, TMI），以及漂流浮标与锚定浮标的原位观测数据。该产品生成的海表温度（Sea Surface Temperature, SST）场平滑度极高，专为支持将海表温度数据同化至数值天气预报（Numerical Weather Prediction, NWP）模型而研发。
