Data supporting On the step type of continuous propagating positive leader in laboratory-scale long spark discharges
<p>The data supports the manuscript entitled "On the step type of continuous propagating positive leader in laboratory-scale long spark discharges". The *.txt file contains the applied voltage waveform and discharge current waveform. The*.doc file contains the data for Figure 5. The *.rar file contains the high-speed video frames, and can be decompressed and opened. The data can be used freely for scientific purposes with appropriate citation.</p>
High-speed videos for the paper "Correlation between speed of the stepped leader and peak current of the return stroke of lightning flashes"
<p>This page contains one spreadsheets with the data of the analyzed lightning flashes (.xlsx file). And it also has high-speed camera video files (.cine files) that are located inside the Lighning Flashes.rar folder. The videos can be watched frame by frame to reproduce the analysis done in the paper titled "Correlation between speed of the stepped leader and peak current of the return stroke of lightning flashes", submitted for publication in Geophysical Research Letters.</p> <p>Instructions to watch the videos: </p> <p>Download and use the software Phantom Camera Control (PCC) available at:</p> <p>https://www.phantomhighspeed.com/resourcesandsupport/phantomresources/pccsoftware</p> <p>The Phantom Camera Control (PCC) software is compatible with Windows 7 Pro and Windows 8.1 and Windows 10, for both 32 and 64-bit operating systems.</p>
Data used in the publication "The emission of terrestrial gamma-ray flashes associated to streamer coronae of the final leader step"
<p>Simulation data used to create Fig. 2 of "The emission of terrestrial gamma-ray flashes associated to streamer coronae of the final leader step"</p>
On the stepped-leader development of negative cloud-to-ground lightning associated with the evolution of thunderstorm
<p>The files contain the complete radar and lightning datasets of the 12 thunderstorms used in the analysis presented in “On the stepped-leader development of negative cloud-to-ground lightning associated with the evolution of thunderstorms.”</p>
Spectral hardness of X- and gamma-ray emissions from lightning stepped and dart leaders
<p>This repository has four folders dedicated to the 11 triggers outlined in the manuscript. Within each folder, the data is organized according to the four sensors:</p><ol><li><strong>Slow Antenna Folder:</strong> For every trigger, there is a corresponding .asc file paired with a complementary .readme file. Additionally, this folder includes a <i>.txt </i>file that lists the file names and UTC times.</li><li><strong>LEFA:</strong> The <i>*.txt</i> files within this section consist of four columns representing seconds after midnight (UTC), instrument power voltage, sensitive channel, medium channel, and unsensitive channel. The file names adhere to the format <i>lefa2-yymmdd-hhmm00.txt</i>, each containing one minute of LEFA data.</li><li><strong>DAS:</strong> Files in this category follow the format <i>XRAY_yyyy.mm.dd_hh-mm-ss_milliseconds.channel[B,C, or D].csv</i>, with UTC time. The file name corresponds to time zero in the data. The first column denotes seconds from/after zero, while the second column represents the measured data in Volts. The channels (B, C, D) correspond to Fast Antenna, LaBr detector, and NaI detector, respectively. The instrument has a sampling rate of 180 MHz.</li><li><strong>Fieldmill:</strong>The file names in this section adhere to the format<i> kv2022mmdd-hhmm.flt </i>and are accompanied by a calibration file.</li></ol>
Simulation data used in "Modeling the Inception and Stepped Propagation of Positive Lightning Leaders"
<p>This dataset includes all simulation data used in "Modeling the Inception and Stepped Propagation of Positive Lightning Leaders." These datasets are output from an upward leader model, described in the paper, under a variety of different conditions and settings. Included also are several charts and animations for select datasets.</p>
Data for "The Spatial Evolution of Upward Positive Stepped Leaders Initiated from a 356-m-High Tower in Southern China"
<p>Here we presented the high-speed video, B-field data and E-field data of two cases (Case 1 & 2) analyzed in a manuscript entitled "The Spatial Evolution of Upward Positive Stepped Leaders Initiated from a 356-m-High Tower in Southern China". The video files can be opened by a software named as 'Phantom Camera Control Application', while the B-field & E-field data can be opende by Matlab. The data supports the aforementioned manuscript and can be used freely for scientific purposes after a request is made to author Mingli Chen.</p>
