GHRSST Level 2P Global Skin Sea Surface Temperature from the Infrared Atmospheric Sounding Interferometer (IASI) on the MetOp-A satellite (GDS2 version) for 2016-02-22 (NCEI Accession 0154467)

A global 1 km Group for High Resolution Sea Surface Temperature (GHRSST) Level 2P dataset based on multi-channel sea surface temperature (SST) retrievals generated in real-time from the Infrared Atmospheric Sounding Interferometer (IASI) on the European Meteorological Operational-A (MetOp-A）satellite （launched 19 Oct 2006). The MetOp satellite program is a European undertaking providing weather data services for monitoring climate and improving weather forecasts. It was jointly established by the European Space Agency (ESA) and the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) with a contribution by the US National Oceanic and Atmospheric Administration (NOAA) of an AVHRR sensor identical to those flying on the family of Polar Orbiting Environmental Satellites (POES). IASI measures in the infrared part of the electromagnetic spectrum at a horizontal resolution of 12 km over a swath width of about 2,200 km. With 14 orbits in a sun-synchronous mid-morning orbit (9:30 Local Solar Time equator crossing, descending node) global observations can be provided twice a day.The production of the MetOp-A L2P SST data is done by the European Organization for the Exploitation of Meteorological Satellites (EUMETSAT), Ocean and Sea Ice Satellite Application Facility (OSI SAF) at Meteo-France/Centre de Meteorologie Spatiale (CMS) in France. The SST retrieval is performed and provided by the IASI L2 processor. The IASI L2P is referred to as core as it does not contain all the auxiliary information (including sea-ice, aerosol, SST background) as specified in a full GHRSST L2P file. These are the main constituents of the IASI L2Pcore SST: skin sea surface temperature, uncertainty estimates (SSES), quality levels and flags, and wind speed. The MetOp-A SST L2P data consist of global coverage at 1.1 km (nadir) resolution separated into three minute observation granules, and are compliant with the GHRSST Data Processing Specification (GDS) version 2 format specifications.本数据集为高分辨率海表温度工作组（Group for High Resolution Sea Surface Temperature, GHRSST）全球1公里2P级数据集，基于欧洲气象业务卫星-A（MetOp-A，2006年10月19日发射）搭载的红外大气探测干涉仪（Infrared Atmospheric Sounding Interferometer, IASI）实时生成的多通道海表温度（sea surface temperature, SST）反演结果构建。 MetOp卫星计划是欧洲主导的科研项目，旨在提供气象数据服务以支撑气候监测与天气预报优化。该计划由欧洲空间局（European Space Agency, ESA）与欧洲气象卫星应用组织（European Organisation for the Exploitation of Meteorological Satellites, EUMETSAT）联合发起，美国国家海洋和大气管理局（US National Oceanic and Atmospheric Administration, NOAA）捐赠了与极轨环境卫星（Polar Orbiting Environmental Satellites, POES）系列搭载型号一致的AVHRR传感器。 IASI工作于电磁波谱的红外波段，水平分辨率为12公里，幅宽约2200公里。该卫星采用上午太阳同步轨道（当地太阳时9:30过赤道降交点），每日可完成14次轨道运行，从而实现每日两次全球覆盖观测。 MetOp-A的2P级SST数据由欧洲气象卫星应用组织（EUMETSAT）下属的海洋与海冰卫星应用设施（Ocean and Sea Ice Satellite Application Facility, OSI SAF），于法国气象局空间气象中心（Centre de Meteorologie Spatiale, CMS）完成生产。SST反演工作由IASI L2处理器完成并提供。 IASI L2P被称为核心版本，因其未包含完整GHRSST 2P级文件中规定的全部辅助信息（包括海冰、气溶胶、SST背景场等）。IASI L2P核心SST产品的主要组成要素包括：表层海表温度、不确定性估计值（SSES）、质量等级与质控标识，以及风速。 MetOp-A的SST 2P级数据采用1.1公里（星下点）分辨率实现全球覆盖，以3分钟观测粒为单元进行分割，且符合GHRSST数据处理规范（GHRSST Data Processing Specification, GDS）2.0版本的格式要求。
