GHRSST Level 2P Global skin Sea Surface Temperature from the Infrared Atmospheric Sounding Interferometer (IASI) on the Metop-B satellite (GDS V2) produced by OSI SAF for 2017-05-22 (NCEI Accession 0163664)

A 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-B (MetOp-B)satellite (launched 17 Sep 2012).

The European Organization for the Exploitation of Meteorological Satellites (EUMETSAT),
Ocean and Sea Ice Satellite Application Facility (OSI SAF) is producing SST products in near real
time from METOP/IASI. The Infrared Atmospheric Sounding Interferometer (IASI) measures in
the infrared part of the electromagnetic spectrum at a horizontal resolution of 12 km at nadir up to
40km 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 SST retrieval is performed and provided by the IASI L2 processor at
EUMETSAT headquarters. The product format is compliant with the GHRSST Data Specification
(GDS) version 2.

高分辨率海表温度工作组（Group for High Resolution Sea Surface Temperature, GHRSST）2P级数据集，基于多通道海表温度（sea surface temperature, SST）反演结果构建，该反演结果由欧洲气象业务-B（European Meteorological Operational-B, MetOp-B）卫星搭载的红外大气探测干涉仪（Infrared Atmospheric Sounding Interferometer, IASI）实时生成，该卫星于2012年9月17日发射。

欧洲气象卫星组织（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）正基于METOP/IASI数据生产准实时海表温度产品。红外大气探测干涉仪（IASI）工作于电磁波谱红外波段，星下点处水平分辨率为12千米，在约2200千米的扫描幅宽范围内，水平分辨率随观测位置远离星下点逐渐降至40千米。该卫星运行于太阳同步早间轨道（当地太阳时9:30赤道降交点过境），每日可完成约14次轨道循环，可实现每日两次的全球观测覆盖。海表温度反演工作由欧洲气象卫星组织总部的IASI L2处理器完成并输出。该产品格式符合高分辨率海表温度数据规范（GHRSST Data Specification, GDS）2.0版本要求。
