Operational Geophysical Data Record (netCDF) - Jason-3

The Operational Geophysical Data Record (OGDR) is a near real-time operational product delivered to users within 3 - 5 hours from instrument sensing. The main geophysical parameters in the OGDR product, derived from the Poseidon altimeter on-board the Jason2 satellite, are significant wave height and ocean surface wind speed. Additionally, all necessary magnitudes contributing to the estimation of the sea surface height are provided as well, such altimeter ranges, orbit data (altitude), water vapour correction, geophysical corrections and geophysical references. Finally, other important parameters, intended to help with the interpretation and use of the data for different applications, are provided as well, such as for example backscatter coefficients and a range of instrument and processing quality flags. Both 1Hz and 20Hz sampling data are included. This product is mainly targeting operational weather and ocean forecasting applications. This data set is jointly generated by NOAA and EUMETSAT. Jason-3 is a contributing mission of the EU Copernicus Programme.业务地球物理数据记录（Operational Geophysical Data Record，OGDR）是一种近实时业务产品，可在仪器感应后3至5小时内交付给用户。该产品的主要地球物理参数源自Jason-2卫星搭载的波塞冬（Poseidon）高度计，包括有效波高和海面风速。此外，数据集还提供了所有用于估算海面高度所需的相关量值，例如高度计测距数据、轨道数据（轨道高度）、水汽校正、地球物理校正项及地球物理参考基准。最后，还提供了其他有助于数据解读与多场景应用的重要参数，例如后向散射系数，以及一系列仪器与处理质量标记。本数据集包含1Hz与20Hz两种采样率的数据，主要面向业务气象与海洋预报应用。本数据集由美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration，NOAA）与欧洲气象卫星应用组织（European Organisation for the Exploitation of Meteorological Satellites，EUMETSAT）联合生成。Jason-3任务是欧盟哥白尼计划（EU Copernicus Programme）的参与任务之一。
