GHRSST Level 4 MUR Global Foundation Sea Surface Temperature Analysis (v4.1) for 2017-05-29 (NCEI Accession 0164036)

A Group for High Resolution Sea Surface Temperature (GHRSST) Level 4 sea surface temperature analysis produced as a retrospective dataset (four day latency) and near-real-time dataset (one day latency) at the JPL Physical Oceanography DAAC using wavelets as basis functions in an optimal interpolation approach on a global 0.01 degree grid. The version 4 Multiscale Ultrahigh Resolution (MUR) L4 analysis is based upon nighttime GHRSST L2P skin and subskin SST observations from several instruments including the NASA Advanced Microwave Scanning Radiometer-EOS (AMSRE), the Moderate Resolution Imaging Spectroradiometer (MODIS) on the NASA Aqua and Terra platforms, the US Navy microwave WindSat radiometer, Advanced Very High Resolution Radiometer (AVHRR) on several NOAA satellites, and in situ SST observations from the NOAA iQuam project. The ice concentration data are from the archives at the EUMETSAT Ocean and Sea Ice Satellite Application Facility (OSI SAF) High Latitude Processing Center and are also used for an improved SST parameterization for the high-latitudes. This data set is funded by the NASA MEaSUREs program(http://earthdata.nasa.gov/our-community/community-data-system-programs/measures-projects), and created by a team led by Dr. Toshio M. Chin from JPL. This dataset adheres to the GHRSST Data Processing Specification (GDS) version 2 format specifications.

本数据集为高分辨率海表温度（Group for High Resolution Sea Surface Temperature, GHRSST）四级海表温度分析产品，由美国喷气推进实验室（Jet Propulsion Laboratory, JPL）物理海洋学分布式活动档案中心制作，采用以小波为基函数的最优插值方法，在全球0.01度网格上生成，包含延迟4天的回溯性数据集与延迟1天的近实时数据集。其第四版多尺度超高分辨率（Multiscale Ultrahigh Resolution, MUR）四级分析产品，基于多类仪器获取的夜间GHRSST L2P级表皮与次表皮海表温度观测数据构建，相关仪器包括美国国家航空航天局（National Aeronautics and Space Administration, NASA）先进微波扫描辐射计-EOS（Advanced Microwave Scanning Radiometer-EOS, AMSRE）、搭载于NASA Aqua与Terra平台的中分辨率成像光谱仪（Moderate Resolution Imaging Spectroradiometer, MODIS）、美国海军微波WindSat辐射计、多颗美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration, NOAA）卫星搭载的先进甚高分辨率辐射计（Advanced Very High Resolution Radiometer, AVHRR），以及NOAA iQuam项目获取的原位海表温度观测数据。本数据集所用的海冰浓度数据源自欧洲气象卫星开发组织（European Organisation for the Exploitation of Meteorological Satellites, EUMETSAT）海洋与海冰卫星应用设施（Ocean and Sea Ice Satellite Application Facility, OSI SAF）高纬度处理中心的档案库，同时被用于优化高纬度区域的海表温度参数化方案。本数据集由NASA MEaSUREs项目（http://earthdata.nasa.gov/our-community/community-data-system-programs/measures-projects）资助，由美国喷气推进实验室的Toshio M. Chin博士领导的团队研发完成。本数据集符合GHRSST数据处理规范（GHRSST Data Processing Specification, GDS）2.0版的格式要求。
