Mapping Lightning in the Sky With a Mini Array [PDF]
Geophysical Research Letters, 2016 AbstractMini arrays are commonly used for infrasonic and seismic studies. Here we report for the first time the detection and mapping of distant lightning discharges in the sky with a mini array. The array has a baseline to wavelength ratio ∼4.2·10−2 to record very low frequency electromagnetic waves from 2 to 18 kHz.

Spatio-Temporal Dimension of Lightning Flashes Based on Three-Dimensional Lightning Mapping Array [PDF]
Atmospheric Research, 2017 3D mapping system like the LMA - Lightning Mapping Array - are a leap forward in lightning observation. LMA measurements has lead to an improvement on the analysis of the fine structure of lightning, allowing to characterize the duration and maximum extension of the cloud fraction of a lightning flash.

First Data of the Colombia Lightning Mapping Array — COLMA [PDF]
2016 33rd International Conference on Lightning Protection (ICLP), 2016 The first data set of VHF lightning mapping using a Lightning Mapping Array system - LMA in a tropical region is presented in this paper. Six sensors were installed at the north of Colombia near Santa Marta city. Since the installation of the LMA network in 2015, up to 7000 intra-cloud (IC) discharges from September to November 2015 have been analyzed.

Lightning Flash Properties Derived From Lightning Mapping Array Data
2014 International Conference on Lightning Protection (ICLP), 2014 in this paper size and duration of lightning flashes are examined. Data from the Ebro Valley Laboratory Lightning Mapping Array is used as reference. Additional data from the VLF/LF LINET network and meteorological radar is included. In order to simplify the complex geometry of a lightning flash, each flash is described by a confidence ellipse fitting ...

Accuracy of the Lightning Mapping Array [PDF]
Journal of Geophysical Research D: 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.

Characteristics of Lightning Within Electrified Snowfall Events Using Lightning Mapping Arrays [PDF]
Journal of Geophysical Research D: Atmospheres, 2018 AbstractThis study examined 34 lightning flashes within four separate thundersnow events derived from lightning mapping arrays (LMAs) in northern Alabama, central Oklahoma, and Washington DC. The goals were to characterize the in‐cloud component of each lightning flash, as well as the correspondence between the LMA observations and lightning data taken

AbstractDuring November 2018–April 2019, an 11-station very high frequency (VHF) Lightning Mapping Array (LMA) was deployed to Córdoba Province, Argentina. The purpose of the LMA was validation of the Geostationary Lightning Mapper (GLM), but the deployment was coordinated with two field campaigns.
