The MIRA 35c radar is a Doppler polarimetric radar working at 35 GHz (Ka-band) with a vertical resolution of 28.9 m and a time resolution of approximately 2 s. For the analysis, we considered radar data whose radar reflectivity was at least 10 dBZ at 5 km or higher above the radar to ensure that there was a cloud above the radar. We divided the radar data into \u201cnear\u201d data (a lightning discharge was registered up to 1 km from the radar position) and \u201cfar\u201d data (a lightning discharge was registered from 7.5 to 10 km from the radar position). We compared the following quantities: (i) Power in co-channel (pow), (ii) power in cross-channel (pow-cx), (iii) phase in co-channel (pha), (iv) phase in cross-channel (pha-cx), (v) equivalent radar reflectivity (Ze), (vi) Linear Depolarization Ratio (LDR), (vii) co-polar correlation coefficient (RHO), (viii) Doppler radial velocity (V), (ix) Doppler spectrum width (RMS), and (x) Differential phase (Phi). Pow, pow-cx, pha, pha-cx, and V are basic data measured by the radar, while Ze, LDR, RHO, RMS, and Phi are derived quantities. Our results showed that the characteristics of the compared radar quantities are clearly distinct for \u201cnear\u201d dataset from \u201cfar\u201d dataset. Furthermore, we found out that there is a clear evolution close to the time of discharges of the observed radar quantities in the \u201cnear\u201d dataset, which is not that obvious in the \u201cfar\u201d dataset.<\/jats:p>","DOI":"10.3390\/rs15112874","type":"journal-article","created":{"date-parts":[[2023,6,1]],"date-time":"2023-06-01T02:12:45Z","timestamp":1685585565000},"page":"2874","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Comparison of Cloud Structures of Storms Producing Lightning at Different Distance Based on Five Years Measurements of a Doppler Polarimetric Vertical Cloud Profiler"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9408-9138","authenticated-orcid":false,"given":"Zbyn\u011bk","family":"Sokol","sequence":"first","affiliation":[{"name":"Institute of Atmospheric Physics, Czech Academy of Sciences, Bo\u010dn\u00ed II 1401, 141 00 Prague, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8870-9126","authenticated-orcid":false,"given":"Jana","family":"Popov\u00e1","sequence":"additional","affiliation":[{"name":"Institute of Atmospheric Physics, Czech Academy of Sciences, Bo\u010dn\u00ed II 1401, 141 00 Prague, Czech Republic"},{"name":"Faculty of Science, Charles University, Albertov 6, 128 00 Prague, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kate\u0159ina","family":"Skripnikov\u00e1","sequence":"additional","affiliation":[{"name":"Institute of Atmospheric Physics, Czech Academy of Sciences, Bo\u010dn\u00ed II 1401, 141 00 Prague, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5461-9728","authenticated-orcid":false,"given":"Rosa Claudia","family":"Torcasio","sequence":"additional","affiliation":[{"name":"National Research Council of Italy, Institute of Atmospheric Sciences and Climate (CNR-ISAC), via del Fosso del Cavaliere 100, 00133 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7890-9394","authenticated-orcid":false,"given":"Stefano","family":"Federico","sequence":"additional","affiliation":[{"name":"National Research Council of Italy, Institute of Atmospheric Sciences and Climate (CNR-ISAC), via del Fosso del Cavaliere 100, 00133 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ond\u0159ej","family":"Fi\u0161er","sequence":"additional","affiliation":[{"name":"Institute of Atmospheric Physics, Czech Academy of Sciences, Bo\u010dn\u00ed II 1401, 141 00 Prague, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,5,31]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"547","DOI":"10.1175\/2007JTECHA1007.1","article-title":"On Deriving Vertical Air Motions from Cloud Radar Doppler Spectra","volume":"25","author":"Shupe","year":"2008","journal-title":"J.
