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.

Imaging lightning intracloud initial stepped leaders by low‐frequency interferometric lightning mapping array [PDF]
Geophysical Research Letters, 2016 By comparing the source position of pulses during initial leaders and the paths of subsequent dart leaders from typical bilevel intracloud (IC) flashes, we demonstrate a new method to image the detailed three‐dimensional (3‐D) structure and stepping ...

Dancing Sprites Above a Lightning Mapping Array—An Analysis of the Storm and Flash/Sprite Developments [PDF]
Journal of Geophysical Research D: Atmospheres, 2021 Abstract One of the most enigmatic types of sprites is the dancing sprite which appears to dance above the storm as sequential luminous emissions a few 100 ms or less apart. Dancing sprites occur in relatively small proportion and many aspects of their generation remain unknown.

Lightning VHF Radiation Mapping Method for an Irregular Short‐Baseline Array
Earth and Space Science, 2023 Lightning very high frequency interferometry is a crucial tool for studying the development of lightning leaders within thunderclouds, and the conventional antenna array is composed of two coplanar orthogonal baselines.

Lightning Mapping Array flash detection performance with variable receiver thresholds [PDF]
Journal of Geophysical Research D: Atmospheres, 2016 AbstractThis study characterizes Lightning Mapping Array performance for networks that participated in the Deep Convective Clouds and Chemistry field program using new Monte Carlo and curvature matrix model simulations. These open‐source simulation tools are readily adapted to real‐time operations or detailed studies of performance.

High altitude leaders mapped by the Colombia lightning mapping array [PDF]
, 2016 On April 2015 a Lightning Mapping Array network (COL-LMA) was installed at the north of Colombia. This network provides 3D mapping of the development of lightning leaders. For the first time such network has been setup in the tropics. That allows us to investigate the high altitude development of lightning leaders.

Basic lightning flash properties derived from lightning mapping array data [PDF]
, 2016 The 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 is included. In the analysis, each flash is simplified by a confidence ellipse fitting most of the detected sources.

Correlated lightning mapping array and radar observations of the initial stages of three sequentially triggered Florida lightning discharges [PDF]
Journal of Geophysical Research D: Atmospheres, 2013 Correlated Lightning Mapping Array and vertical‐scan radar images are presented for three rocket‐and‐wire triggered lightning flashes that occurred sequentially within 17 min in the presence of a decaying multicellular convective storm system over north‐central Florida.
