BlackJack Level 1B Bending Angle Climate Data Record Release 1 - GRACE

The GRACE Level 1 Bending Angle Fundamental Climate Data Record (FCDR) Release 1 comprises reprocessed Level 1B Radio Occultation (RO) bending-angle data from GPS RO measurements onboard the twin satellite configuration Gravity Recovery and Climate Experiment (GRACE) covering the period 2007-2017. The software used to perform the reprocessing is EUMETSAT’s reference RO processor (Yaros 2.0), which uses a “wave optics” (fast phase transform) retrieval algorithm algorithm. The data record has global coverage and is available in two formats: individual occultation Network Common Data Form 4 (netCDF4) files and individual occultation Binary Universal Form for the Representation of meteorological data (BUFR) files. This is an Fundamental Climate Data Record (FCDR) produced for the Copernicus Climate Change Service.重力恢复与气候实验（Gravity Recovery and Climate Experiment, GRACE）第1版1级B档弯曲角基础气候数据记录（Fundamental Climate Data Record, FCDR）数据集，包含2007年至2017年期间，搭载于该双星构型任务的GPS无线电掩星（Radio Occultation, RO）观测数据经再处理后得到的1级B档无线电掩星弯曲角数据。本次再处理所使用的软件为欧洲气象卫星应用组织（European Organisation for the Exploitation of Meteorological Satellites, EUMETSAT）的参考无线电掩星处理器Yaros 2.0，其采用“波光学（快速相位变换）”反演算法。该数据记录具备全球覆盖范围，提供两种存储格式：单掩星事件网络通用数据格式4（Network Common Data Form 4, netCDF4）文件，以及单掩星事件气象数据二进制通用格式（Binary Universal Form for the Representation of meteorological data, BUFR）文件。本数据集是为哥白尼气候变化服务（Copernicus Climate Change Service）制作的基础气候数据记录。
