Cross-Correlation Wavelet-Domain-Based Particle Swarm Optimization for Lightning Mapping

Applied Sciences, 2021
Several processing methods have been proposed for estimating the real pattern of the temporal location and spatial map of the lightning strikes. However, due to the complexity of lightning signals, providing accurate lightning maps estimation remains a ...

Advances in Lightning Monitoring and Location Technology Research in China

Remote Sensing, 2022
Monitoring lightning and its location is important for understanding thunderstorm activity and revealing lightning discharge mechanisms. This is often realized based on very low-frequency/low-frequency (VLF/LF) signals, very high-frequency (VHF) signals,

Accuracy of the Lightning Mapping Array [PDF]

Journal of Geophysical Research: Atmospheres, 2004
The location accuracy of the New Mexico Tech Lightning Mapping Array (LMA) has been investigated experimentally using sounding balloon measurements, airplane tracks, and observations of distant storms. We have also developed simple geometric models for estimating the location uncertainty of sources both over and outside the network.

Lightning‐Produced Nitrogen Oxides Per Flash Length Obtained by Using TROPOMI Observations and the Ebro Lightning Mapping Array

Geophysical Research Letters, 2023
Lightning is one of the main sources of NOx in the Earth's atmosphere. However, there is a large variability in NOx production during the lifetime of thunderstorms.
