GHRSST Level 3C North Atlantic Regional (NAR) subskin Sea Surface Temperature from Metop/AVHRR (GDS V2) produced by OSI SAF for 2017-06-03 (NCEI Accession 0163955)

A Group for High Resolution Sea Surface Temperature (GHRSST) dataset for the North Atlantic Region (NAR) derived from the Advanced Very High Resolution Radiometer (AVHRR) on the European Meteorological Operational-B (MetOp-B) platform (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/AVHRR and SNPP/VIIRS. Global AVHRR level 1b data are acquired at Meteo-
France/Centre de Meteorologie Spatiale (CMS) through the EUMETSAT/EUMETCAST system.
NAR SNPP/VIIRS level 0 data are acquired through direct readout and converted into l1b at CMS.
SST is retrieved from the AVHRR and VIIRS infrared channels using a multispectral algorithm.
This product is delivered as four six hourly collated files per day on a regular 2km grid. The
product format is compliant with the GHRSST Data Specification (GDS) version 2.

高精度海表温度工作组（Group for High Resolution Sea Surface Temperature，缩写GHRSST）面向北大西洋区域（North Atlantic Region，缩写NAR）的数据集，该数据集源自搭载于欧洲气象业务-B（European Meteorological Operational-B，缩写MetOp-B）平台（2012年9月17日发射）上的甚高分辨率辐射计（Advanced Very High Resolution Radiometer，缩写AVHRR）。

欧洲气象卫星开发组织（European Organization for the Exploitation of Meteorological Satellites，缩写EUMETSAT）下属的海洋与海冰卫星应用设施（Ocean and Sea Ice Satellite Application Facility，缩写OSI SAF）正基于MetOp/AVHRR与SNPP/VIIRS（Visible Infrared Imaging Radiometer Suite，缩写VIIRS）生成近实时海表温度（Sea Surface Temperature，缩写SST）产品。全球AVHRR 1b级数据通过EUMETSAT/EUMETCAST系统，由法国气象局/空间气象中心（Meteo-France/Centre de Meteorologie Spatiale，缩写CMS）获取。北大西洋区域的SNPP/VIIRS 0级数据通过直接读取方式获取，并于CMS处转换为1b级数据。采用多光谱算法，从AVHRR与VIIRS的红外通道中反演得到海表温度。该产品以每日4份每6小时整合一次的文件形式发布，采用标准2km网格格式，其数据格式符合GHRSST数据规范（GHRSST Data Specification，缩写GDS）2.0版本要求。
