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.

Timing Calibration and Windowing Technique Comparison for Lightning Mapping Arrays [PDF]

Earth and Space Science, 2021
Since their introduction 22 years ago, lightning mapping arrays (LMA) have played a central role in the investigation of lightning physics. Even in recent years with the proliferation of digital interferometers and the introduction of the LOw Frequency ...

Characteristics of Lightning Within Electrified Snowfall Events Using Lightning Mapping Arrays [PDF]

Journal of Geophysical Research: 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

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

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.

Upgraded Low-Frequency 3D Lightning Mapping System in North China and Observations on Lightning Initiation Processes

Remote Sensing
The three-dimensional (3D) low-frequency lightning mapping system (LF-LMS) in north China has been updated. The lightning electric field derivative (dE/dt) sensor and continuous acquisition mode has been newly designed to ensure a capability of entire ...

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.

Genome‐wide association analysis of resistance to scald in an adapted multiparent winter malting barley population [PDF]

The Plant Genome, Volume 19, Issue 4, December 2026.
Abstract Scald, caused by the fungus Rhynchosporium graminicola Heinsen 1897, is a major foliar disease in winter malting barley (Hordeum vulgare L). Resistance to scald in winter malting barley is controlled by major and minor resistance genes. We used a population of 377 lines derived from biparental crosses among five winter malting barley parents ...

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 ...
