GHRSST Level 4 MW_OI Global Foundation Sea Surface Temperature analysis for 2017-05-22 (NCEI Accession 0164047)

A Group for High Resolution Sea Surface Temperature (GHRSST) global Level 4 sea surface temperature analysis produced daily on a 0.25 degree grid at Remote Sensing Systems. This product uses optimal interpolation (OI) from microwave (MW) sensors including the NASA Advanced Microwave Scanning Radiometer-EOS (AMSRE), 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. The through-cloud capabilities of microwave radiometers provide a valuable picture of global sea surface temperature (SST). 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（Remote Sensing Systems）每日以0.25°网格分辨率生成。本产品采用最优插值（optimal interpolation, OI）方法融合多类微波（microwave, MW）传感器数据，所用传感器包括美国国家航空航天局先进微波扫描辐射计-地球观测系统（NASA 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）、搭载于GCOM-W1卫星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。微波辐射计的穿云观测能力可为全球海表温度（sea surface temperature, SST）监测提供极具价值的观测图景。本分析产品未使用任何原位海表温度数据，例如漂流浮标获取的海表温度数据。
