OSTIA L4 SST Analysis for 2016-07-20 (NCEI Accession 0158643)

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面温度工作组（Group for High Resolution Sea Surface Temperature, GHRSST）四级海表面温度分析产品，由英国气象局（UK Met Office）依托最优插值（optimal interpolation, OI）方法，在全球0.054度网格上每日业务化生成。该业务化海表面温度与海冰分析（Operational Sea Surface Temperature and Sea Ice Analysis, OSTIA）所采用的卫星数据涵盖甚高分辨率辐射计（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），同时辅以漂流浮标与系泊浮标的原位观测数据。本分析生成的海表面温度（Sea Surface Temperature, SST）场具有高度平滑的特性，其研发目的是为将海表面温度数据同化至数值天气预报（Numerical Weather Prediction, NWP）模型提供支撑。
