GHRSST Level 4 MUR Global Foundation Sea Surface Temperature Analysis (v4.1) for 2016-05-16 (NCEI Accession 0154454)

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.

高精度海表温度（Sea Surface Temperature, SST）工作组（Group for High Resolution Sea Surface Temperature, GHRSST）四级海表温度分析产品，由JPL物理海洋学分布式主动存档中心（Physical Oceanography DAAC）生成，包含回溯延迟数据集（延迟4天）与近实时延迟数据集（延迟1天），采用以小波函数为基函数的最优插值方法，在全球0.01度网格上生成。本数据集中的V4版多尺度超分辨率（Multiscale Ultrahigh Resolution, MUR）四级分析产品，基于夜间GHRSST L2P级海表皮肤温度与海表次皮肤温度观测数据，观测来源涵盖多款传感器：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-地球观测系统（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），以及来自NOAA iQuam项目的原位海表温度观测数据。海冰密集度数据来源于欧洲气象卫星组织（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）高纬度处理中心的存档数据，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计划(http://earthdata.nasa.gov/our-community/community-data-system-programs/measures-projects)资助，由JPL的Toshio M. Chin博士领导的团队构建。该数据集符合GHRSST数据处理规范（GHRSST Data Processing Specification, GDS）版本2的格式要求。
