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 2017-05-07 (NCEI Accession 0163276)

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.

本数据集为高分辨率海表面温度组（Group for High Resolution Sea Surface Temperature, GHRSST）2P级数据集，其数据源自2012年9月17日发射的欧洲气象业务-B（MetOp-B）卫星搭载的红外大气探测干涉仪（Infrared Atmospheric Sounding Interferometer, IASI）实时生成的多通道海表面温度（Sea Surface Temperature, SST）反演结果。
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以近实时方式生成SST产品。红外大气探测干涉仪（IASI）可在电磁光谱的红外波段开展探测，星下点水平分辨率为12 km，在约2200 km的刈幅宽度范围内，边缘分辨率可达40 km。该卫星运行于太阳同步早间轨道（赤道降交点地方太阳时间为9:30），每日可完成14次轨道运行，从而实现每日两次的全球观测覆盖。海表面温度反演工作由欧洲气象卫星组织总部的IASI L2处理器完成并对外提供，产品格式符合GHRSST数据规范（GHRSST Data Specification, GDS）2.0版本要求。
