GHRSST Level 4 MW_IR_OI Global Foundation Sea Surface Temperature analysis for 2017-05-24 (NCEI Accession 0163691)

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.由遥感系统（Remote Sensing Systems）生成的高精度海表温度工作组（Group for High Resolution Sea Surface Temperature，GHRSST）全球四级海表温度分析产品，以0.81度网格分辨率每日生成。该产品采用最优插值（optimal interpolation，OI）算法，融合多类微波与红外传感器数据：微波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（AMSRE）、热带降雨测量任务微波成像仪（TMI）、搭载于GCOM-W1卫星的先进微波扫描辐射计2号（AMSR2），以及科里奥利卫星搭载的WindSat辐射计；红外传感器则包括NASA Aqua与Terra平台上的中分辨率成像光谱辐射计（MODIS）。微波辐射计具备穿透云层的观测能力，可有效刻画全球海表温度（sea surface temperature，SST）分布格局，而红外辐射计（如MODIS）则拥有更高的空间分辨率。该分析产品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。
