GHRSST Level 2P Western Atlantic Regional Skin Sea Surface Temperature from the Geostationary Operational Environmental Satellites (GOES) Imager on the GOES-13 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-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（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。当前在轨运行的GOES卫星通常有数颗，分别观测不同的地球区域，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）成像辐射计，旨在探测地球采样区域的辐射能量与太阳反射能量。其多单元光谱通道借助双轴镜面扫描系统沿南北路径完成东西向与西东向同步扫描，以10位精度对遥测数据进行调谐。针对本次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-13卫星的远红外通道，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）观测数据。在原生卫星投影模式下，垂直相邻的像素将被平均后逐像素输出。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。完整圆盘影像将被裁剪为若干数据分块，分别对应独立的南北区域。
