Micro rain radar (MRR) raw data measured at Neumayer Station (2023-03), links to files

The meteorological observatory Neumayer continuously operates a vertically looking single column 24 GHz meteorological Doppler radar (METEK MRR-PRO) to monitor hydrometeors. The instrument essentially records radar reflectivity and Doppler velocity in 128 vertical range gates. The vertical resolution is set to 50m, hence the maximal altitude is 6400m; the temporal resolution is typically 1 second. The instrument was initially installed in January 2019 and is mounted on the roof of the Neumayer Station III. Since the station altitude changes slightly over time the instrument height above sea level can change over time too. This is documented in the netCDF variable \"range:meters_to_center_of_first_gate\", initially 65m. Since installation an interfering signal which could not be readily identified and removed disturbs the measurements in range gates 7 to 10, i.e. 370m to 520m. The disturbance can easily be identified and filtered for analysis of the data. This dataset contains the full raw data from the instrument. All data published here is left \"as recorded\", no quality control was applied. Still, some concatenation and temporal re-sorting was sporadically applied to homogenise the temporal file granularity. Any such operations are documented in the netCDF global attribute \"history\" of the respective files.诺伊迈尔（Neumayer）气象观测站持续运行一台垂直指向的单柱式24 GHz气象多普勒雷达（METEK MRR-PRO），用于监测水凝物。该设备主要在128个垂直距离门中记录雷达反射率与多普勒速度。其垂直分辨率设为50米，因此最大探测高度可达6400米；时间分辨率通常为1秒。该设备于2019年1月首次安装，搭载于诺伊迈尔三号站（Neumayer Station III）的屋顶。由于观测站海拔随时间发生小幅变化，设备的海平面以上高度也会随之改变，该信息记录于netCDF变量"range:meters_to_center_of_first_gate"中，初始值为65米。自安装以来，一组难以直接识别和消除的干扰信号会对7至10号距离门（对应370米至520米高度区间）的测量结果造成干扰。在开展数据分析时，这类干扰可被轻松识别并滤除。本数据集包含该设备的全部原始数据。此处发布的所有数据均保留"原始记录状态"，未经过任何质量控制处理。不过，为统一时间文件粒度，曾零星执行过数据拼接与时间重排序操作，所有此类操作均记录于对应文件的netCDF全局属性"history"中。
