GHRSST Level 4 DMI_OI Global Foundation Sea Surface Temperature Analysis (GDS version 2)

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温度（GHRSST）第4级海表温度分析结果，由丹麦气象研究所（DMI）以每日操作为基础，采用最优插值（OI）方法在全球0.05度网格上进行生成。该分析基于多颗卫星夜间GHRSST L2P皮肤和次表层海表温度（SST）观测数据。传感器包括先进的甚高分辨率辐射计（AVHRR）、旋转增强型可见光和红外成像仪（SEVIRI）、高级微波扫描辐射计2号（AMSR2）、可见光和红外成像仪辐射计套件（VIIRS）以及搭载于Aqua平台的适度分辨率成像光谱辐射计（MODIS）。此外，利用欧洲气象卫星组织（EUMETSAT）OSI-SAF提供的冰场数据，对有冰区域进行掩蔽。该数据集遵循GHRSST数据处理规范版本2（GDS）。
