The TRIple-frequency and Polarimetric radar Experiment for improving process observation of winter precipitation (version 2)

The combined TRIple-frequency and Polarimetric radar Experiment for improving process observation of winter precipitation (TRIPEx) was a joint field experiment of the University of Cologne, the University of Bonn, the Karlsruhe Institute of Technology (KIT), and the Research Center Jülich. TRIPEx took place at the Jülich Observatory for Cloud Evolution (JOYCE) from 11 November 2015 until 04 January 2016. During this experiment, the X, Ka and W Band ground-based Doppler radars were used vertically pointing to observe the clouds. Here we provide level 2 of the dataset collected during this campaign. Several step processing were applied to minimize the radar offset and attenuation. In addition, we provide the attenuation correction and the quality flags for each processing steps to allow the user to retrieve the data without our correction. The raw and the level 1 of the dataset are available for the users on request from the corresponding author.用于改进冬季降水过程观测的三频段偏振雷达联合试验（TRIPEx），是由科隆大学、波恩大学、卡尔斯鲁厄理工学院（Karlsruhe Institute of Technology, KIT）以及于利希研究中心联合开展的外场观测试验。该试验于2015年11月11日至2016年1月4日在于利希云演化观测台（JOYCE）实施。试验期间，研究团队采用X、Ka、W波段地基多普勒雷达进行垂直指向观测，以获取云体探测数据。本数据集收录本次试验采集的二级（Level 2）数据。为尽可能减小雷达系统偏移与电磁波衰减对数据的影响，已对原始数据开展多步处理。此外，本数据集还附带各处理步骤的衰减校正结果与质量标记，以供用户自主完成数据校正，无需依赖我方提供的校正方案。原始数据集与一级（Level 1）数据集可通过联系通讯作者申请获取。
