GHRSST Level 4 MW_IR_OI Global Foundation Sea Surface Temperature analysis for 2016-02-21 (NCEI Accession 0154471)

A Group for High Resolution Sea Surface Temperature (GHRSST) global Level 4 sea surface temperature analysis produced daily on a 0.81 degree grid at Remote Sensing Systems. This product uses optimal interpolation (OI) from both microwave (MW) sensors including the NASA Advanced Microwave Scanning Radiometer-EOS (AMSRE), and the Tropical Rainfall Measuring Mission Microwave Imager (TMI), the Advanced Microwave Scanning Radiometer 2 (AMSR2) onboard the GCOM-W1 satellite, and WindSat operates on the Coriolis satellite, and infrared (IR) sensors such as the Moderate Resolution Imaging Spectroradiometer (MODIS) on the NASA Aqua and Terra platform. The through-cloud capabilities of microwave radiometers provide a valuable picture of global sea surface temperature (SST) while infrared radiometers (i.e., MODIS) have a higher spatial resolution. This analysis does not use any in situ SST data such as drifting buoy SST.

高分辨率海表温度工作组（Group for High Resolution Sea Surface Temperature，GHRSST）的全球四级海表温度分析产品，由遥感系统公司每日基于0.81度网格生成。本产品采用最优插值（optimal interpolation，OI）方法，对两类传感器数据进行融合：其一为微波（microwave，MW）传感器，包括美国国家航空航天局（NASA）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）、GCOM-W1卫星搭载的先进微波扫描辐射计2号（Advanced Microwave Scanning Radiometer 2，AMSR2），以及科里奥利卫星搭载的WindSat辐射计；其二为红外（infrared，IR）传感器，例如NASA Aqua与Terra平台搭载的中分辨率成像光谱仪（Moderate Resolution Imaging Spectroradiometer，MODIS）。微波辐射计具备穿云观测能力，可获取全球海表温度（sea surface temperature，SST）的有效观测图景，而红外辐射计（如MODIS）拥有更高的空间分辨率。本分析未使用任何原位海表温度数据，例如漂流浮标海表温度数据。
