GHRSST Level 2P Central Pacific Regional Skin Sea Surface Temperature from the Geostationary Operational Environmental Satellites (GOES) Imager on the GOES-15 satellite (GDS version 2) for 2017-05-31 (NCEI Accession 0163888)

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. In native satellite projection, vertically adjacent pixels are averaged and read out at every pixel. L2P datasets including Single Sensor Error Statistics (SSES) are then derived following the GHRSST Data Processing Specification (GDS) version 2.0. The full disk image is subsetted into granules representing distinct northern and southern regions.由美国国家海洋和大气管理局（United States National Oceanic and Atmospheric Administration, NOAA）运营的地球静止业务环境卫星（Geostationary Operational Environmental Satellites, GOES），可支撑天气预报、强风暴追踪以及气象学与海洋学研究工作。当前在轨的GOES卫星通常有多颗处于地球同步轨道，可观测不同地球区域，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成像仪（GOES N-P Imager）为五通道成像辐射计，包含1个可见光通道与4个红外通道，可探测地球采样区域的辐射能与太阳反射能量。多单元光谱通道通过双轴镜扫描系统，沿南北路径同步完成东西、西东向扫描，以10比特精度回传遥测数据。针对高分辨率海表温度工作组（Group for High Resolution Sea Surface Temperature, GHRSST）数据集，研究人员基于GOES-15的远红外通道，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）观测值。在原生卫星投影模式下，垂直相邻的像素将被平均处理并逐像素输出。随后按照《高分辨率海表温度数据处理规范（GHRSST Data Processing Specification, GDS）2.0版》，生成包含单传感器误差统计（Single Sensor Error Statistics, SSES）的L2P数据集。全圆盘影像将被裁剪为代表不同南北区域的数据粒(granules)。
