GHRSST Level 4 DMI_OI Global Foundation Sea Surface Temperature Analysis (GDS version 2) for 2016-03-08 (NCEI Accession 0146245)

A Group for High Resolution Sea Surface Temperature (GHRSST) Level 4 sea surface temperature analysis produced daily on an operational basis by the Danish Meteorological Institute (DMI) using an optimal interpolation (OI) approach on a global 0.05 degree grid. The analysis is based upon nighttime GHRSST L2P skin and subskin SST observations from several satellites. The sensors include the Advanced Very High Resolution Radiometer (AVHRR), the Spinning Enhanced Visible and Infrared Imager (SEVIRI), the Advanced Microwave Scanning Radiometer 2 (AMSR2), the Visible Infrared Imager Radiometer Suite (VIIRS), and the Moderate Resolution Imaging Spectroradiometer (MODIS) on Aqua. An ice field from the EUMETSAT OSI-SAF is used to mask out areas with ice. This dataset adheres to the version 2 GHRSST Data Processing Specification (GDS).本数据集为高分辨率海表面温度工作组（Group for High Resolution Sea Surface Temperature，GHRSST）四级海表面温度分析产品，由丹麦气象研究所（Danish Meteorological Institute，DMI）基于最优插值（optimal interpolation，OI）方法在全球0.05度网格上业务化每日生成。该分析基于多颗卫星获取的夜间GHRSST L2P级表皮与次表皮海表面温度观测数据构建，所用传感器包括先进甚高分辨率辐射计（Advanced Very High Resolution Radiometer，AVHRR）、旋转增强型可见光与红外成像仪（Spinning Enhanced Visible and Infrared Imager，SEVIRI）、先进微波扫描辐射计2号（Advanced Microwave Scanning Radiometer 2，AMSR2）、可见光红外成像辐射计套件（Visible Infrared Imager Radiometer Suite，VIIRS）以及Aqua卫星搭载的中分辨率成像光谱仪（Moderate Resolution Imaging Spectroradiometer，MODIS）。该分析采用欧洲气象卫星应用组织（EUMETSAT）OSI-SAF提供的海冰场数据对冰覆盖区域进行掩膜处理。本数据集符合第二版GHRSST数据处理规范（GHRSST Data Processing Specification，GDS）。
