GHRSST Level 3C America Regional Subskin Sea Surface Temperature from the Geostationary Operational Environmental Satellites (GOES) Imager on the GOES-13 satellite for 2016-02-22 (NCEI Accession 0154466)

A regional Group for High Resolution Sea Surface Temperature (GHRSST) Level 3 Collated (L3C) dataset for the America Region (AMERICAS) based on retrievals from the GOES-13 Imager on board GOES-13 satellite. This particular dataset is produced twice a day over South and North America region in the framework of the European Organization for the Exploitation of Meteorological Satellites (EUMETSAT) Ocean and Sea Ice Satellite Application Facility (OSI SAF) in France.The Geostationary Operational Environmental Satellites (GOES) operated by the United States National Oceanographic 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. The OSI-SAF SST processing chain for geostationary satellite will ingest the GOES13 Imager radiometric data in full time (every 30 minutes) and space resolution, then the NWC (nowcasting) SAF cloud mask is applied. GOES-E algorithm (nighttime only) and its correction are applied. Due to the lack of 12 μm channel in the GOES-Eimager, there are no SST in daytime conditions. The operational products are then produced by remapping over a 0.05 degree regular grid SST fields obtained by aggregating all SST data available in one hour time, and the priority being given to the value the closest in time to the product nominal hour. This dataset produced adheres to the GHRSST Data Processing Specification (GDS) version 2 format specifications.

本数据集为面向美洲区域的高分辨率海表温度（Group for High Resolution Sea Surface Temperature, GHRSST）L3级合并（Level 3 Collated, L3C）数据集，基于GOES-13卫星搭载的GOES-13成像仪反演结果生成。该数据集由法国欧洲气象卫星开发组织（European Organization for the Exploitation of Meteorological Satellites, EUMETSAT）下属的海洋与海冰卫星应用设施（Ocean and Sea Ice Satellite Application Facility, OSI SAF）牵头制作，每日两次覆盖南美与北美区域。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），主要用于天气预报、强风暴追踪以及气象与海洋学研究。当前同一时段通常有多颗GOES卫星处于地球同步轨道，分别观测不同地球区域，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，用于探测地球采样区域的辐射能与太阳反射能。该多单元光谱通道借助双轴镜扫描系统沿南北路径同步开展东西、西东向扫描，以10位精度传输遥测数据。OSI SAF的地球静止卫星海表温度处理链将获取全时间分辨率（每30分钟一次）与全空间分辨率的GOES-13成像仪辐射数据，随后应用短时数值预报（nowcasting, NWC）安全云掩膜。数据集采用仅适用于夜间的GOES-E算法及其修正方案，由于GOES-E成像仪缺失12μm通道，因此日间无法生成海表温度产品。最终业务产品通过以下流程生成：将一小时内所有可用海表温度数据聚合后，重映射至0.05度的规则网格海表温度场，并优先选用距离产品标称时刻最接近的观测值。本数据集严格遵循GHRSST数据处理规范（GHRSST Data Processing Specification, GDS）2.0版格式要求。
