GHRSST Level 2P Western Atlantic Regional Skin Sea Surface Temperature from the Geostationary Operational Environmental Satellites (GOES) Imager on the GOES-13 satellite (GDS version 2) for 2017-05-21 (NCEI Accession 0164073)

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-13 launched 24 May 2006. 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-13 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（National Oceanic and Atmospheric Administration, NOAA）运营的地球静止环境业务卫星（Geostationary Operational Environmental Satellites, GOES），可支撑天气预报、强风暴追踪以及气象与海洋学研究。当前通常同时有多颗GOES卫星运行于地球同步轨道，观测不同地球区域，其中包括2006年5月24日发射的GOES-13卫星。
该卫星搭载的GOES N-P成像仪是一款五通道（1个可见光通道、4个红外通道）的成像辐射计，旨在感应地球采样区域的辐射能量与太阳反射能量。多单元光谱通道通过双轴反射镜扫描系统沿南北路径完成东西向往返扫描，并以10比特精度传回遥测数据。
针对本高分辨率海表温度（Group for High Resolution Sea Surface Temperature, GHRSST）数据集，海面皮肤温度（skin sea surface temperature, SST）测量值由GOES-13的远红外通道以全分辨率每半小时计算生成。在原生卫星投影坐标系中，垂直相邻的像素会被取平均后逐像素输出。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。全圆盘影像会被裁剪为代表不同南北区域的影像数据块。
