LANL Lightning Flash Time Duration Ground Truth
Video cameras were used to record cloud-to-ground (CG) lightning flash events on or near Los Alamos National Laboratory (LANL) over 3 days in August, 2018. Custom scripting software was created to automatically trigger camera recording off National Lightning Data Network (NLDN) streamed reporting of CG lightning within 12 miles of LANL. Cameras were sited near meteorology towers at LANL and 4k video captures were manually reviewed to extract still sequence images from 9 identified CG flashes. A camera frame rate of 30 fps was used to estimate time durations of 33-200 milliseconds over this natural lightning dataset.
