Data Stewardship Maturity Report for GHRSST Level 2P Central Pacific Regional Skin Sea Surface Temperature from the Geostationary Operational Environmental Satellites (GOES) Imager on the GOES-15 satellite (GDS versions 1 and 2)

The Geostationary Operational Environmental Satellites (GOES) operated by the United States National Oceanic and Atmospheric Administration (NOAA) support weather forecasting, severe storm tracking, meteorology and oceanography research. Generally there are several GOES satellites in geosynchronous orbit at any one time viewing different earth locations including the GOES-15 launched 4 March 2010. The radiometer aboard the satellite, The GOES N-P Imager, is a five channel (one visible, four infrared) imaging radiometer designed to sense radiant and solar reflected energy from sampled areas of the earth. The multi-element spectral channels simultaneously sweep east-west and west-east along a north-to-south path by means of a two-axis mirror scan system retuning telemetry in 10-bit precision. For this Group for High Resolution Sea Surface Temperature (GHRSST) dataset, skin sea surface temperature (SST) measurements are calculated from the far IR channels of GOES-15 at full resolution on a half hourly basis.

由美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration, NOAA）运营的地球静止业务环境卫星（Geostationary Operational Environmental Satellites, GOES），可支持天气预报、强风暴追踪以及气象与海洋学研究。当前在轨运行的GOES卫星通常有多颗，各自观测不同的地球区域，其中包括2010年3月4日发射的GOES-15卫星。该卫星搭载的GOES N-P成像辐射计，是一款五波段（1个可见光波段、4个红外波段）的成像辐射计，专为感应地球采样区域的辐射能量与太阳反射能量而设计。借助双轴镜面扫描系统，多单元光谱波段可沿南北路径同步完成东西向与西东向的扫描，并以10比特精度回传遥测数据。针对本次高分辨率海表温度（Group for High Resolution Sea Surface Temperature, GHRSST）数据集，研究人员基于GOES-15的远红外波段，以半小时为周期、全分辨率计算得到表皮海表温度（skin sea surface temperature, SST）测量值。
