On the Space Leader Evolution During the Breakthrough Phase of Attachment Process in Positive Laboratory Sparks

<p>The data supports the manuscript entitled &quot;On the Space Leader Evolution During the Breakthrough Phase of&nbsp;Attachment Process in Positive Laboratory Sparks.&quot; &nbsp;The &quot;Data 1&quot; group contains the discharge current waveform, the normalized gray value, and the synchronized voltage-current-impedance waveform. The files in &quot;Data 1&quot; group can be opened by Excel. The &quot;Data 2&quot; group includes high-speed video frames for five discharge events and they can be opened by Phantom Camera Control (PCC) software. The data can be used freely for scientific purposes with appropriate citation.</p>
