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 2017-05-26 (NCEI Accession 0163706)

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.

基于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）实时反演得到的多通道海表面温度（SST）结果，构建的高分辨率海表面温度工作组（Group for High Resolution Sea Surface Temperature，GHRSST）2P级数据集。

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）正依托METOP/IASI以近实时方式生成SST产品。红外大气探测干涉仪（IASI）工作于电磁波谱红外波段，天底点水平分辨率为12 km，刈幅宽度约2200 km，最大观测分辨率可达40 km。该卫星采用太阳同步早间轨道（地方太阳时间9:30赤道降交点过境），每日可完成14次轨道环绕，从而实现每日两次全球观测覆盖。欧洲气象卫星开发组织总部的IASI L2处理器负责执行并提供SST反演服务，该产品格式符合高分辨率海表面温度工作组数据规范（GHRSST Data Specification，GDS）版本2。
