GHRSST Level 4 MUR Global Foundation Sea Surface Temperature Analysis (v4.1) for 2017-04-01 (NCEI Accession 0163146)

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工作组（Group for High Resolution Sea Surface Temperature, GHRSST）四级海表温度分析产品，由喷气推进实验室（Jet Propulsion Laboratory, JPL）物理海洋学分布式主动存档中心生成，分为回溯性数据集（延迟4天）与近实时数据集（延迟1天），采用以小波为基函数的最优插值方法，在全球0.01度网格上开展计算。版本4的多尺度超分辨率（Multiscale Ultrahigh Resolution, MUR）L4分析，其数据源涵盖多类仪器获取的夜间GHRSST L2P表皮及次表皮海表温度（Sea Surface Temperature, SST）观测数据：包括美国国家航空航天局（NASA）先进微波扫描辐射计-对地观测系统（AMSRE）、NASA Aqua与Terra卫星平台搭载的中分辨率成像光谱仪（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（NOAA）卫星搭载的先进甚高分辨率辐射计（AVHRR），以及NOAA iQuam项目获取的原位海表温度观测数据。海冰密集度数据源自欧洲气象卫星应用组织（EUMETSAT）海洋与海冰卫星应用设施（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项目资助（数据来源链接：http://earthdata.nasa.gov/our-community/community-data-system-programs/measures-projects），由喷气推进实验室Toshio M. Chin博士领衔的团队研发。本数据集符合GHRSST数据处理规范（GHRSST Data Processing Specification, GDS）2.0版本的格式要求。
