The TRIple-frequency and Polarimetric radar Experiment for improving process observation of winter precipitation dataset

<p>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 J&uuml;lich. TRIPEx took place at the J&uuml;lich Observatory for Cloud Evolution (JOYCE) from 11 November 2015 until 04 January 2016.&nbsp; During this experiment, the X-, Ka- and W-band ground-based Doppler radars were used vertically pointing to observe the clouds. Here we provide the 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&nbsp; 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.<br> &nbsp;</p>
