Analysis of charge transport during lightning using balloon‐borne electric field sensors and Lightning Mapping Array [PDF]

open access: yesJournal of Geophysical Research: Atmospheres, 2007
Recently, wide band measurements of the electric field near a lightning flash have been obtained by a balloon‐borne electric field sonde or Esonde. This paper develops new techniques for analyzing lightning‐associated charge transport in a thundercloud by using both the Esonde data and simultaneous Lightning Mapping Array (LMA) measurements of VHF ...

Triggered Calcium Lightning Programs Cochlear Development

open access: yesExploration, EarlyView.
Summary: Before the onset of hearing, the developing inner ear generates spontaneous calcium signals that are thought to guide maturation. In this study, we discovered a rapid and widespread calcium flash—dubbed “Ca2+ lightning”—originating from supporting cells beneath the sensory hair cells, which triggers coordinated calcium waves across the entire ...

Thermal Deformation Correction for the FY-4A LMI

open access: yesRemote Sensing
Affected by solar radiation in space, the FY-4A Lightning Mapping Imager (LMI) detection array exhibits daily periodic thermal expansion and contraction, leading to deviations in lightning positioning accuracy.

From Ashes to Action: Economic Growth, Ecological Footprint, and Forest Fire Resilience in Advanced and Emerging Economies

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Forest fires have escalated alarmingly, now consuming more than double the tree cover compared to two decades ago, signaling a growing and urgent environmental crisis. This study addresses the ever increasing global concern of forest fires, focusing on sustainable economic recovery while minimizing the ecological footprint amid mounting ...

SAETTA: high-resolution 3-D mapping of the total lightning activity in the Mediterranean Basin over Corsica, with a focus on a mesoscale convective system event [PDF]

open access: yesAtmospheric Measurement Techniques, 2019
Deployed on the mountainous island of Corsica for thunderstorm monitoring purposes in the Mediterranean Basin, SAETTA is a network of 12 LMA (Lightning Mapping Array, designed by New Mexico Tech, USA) stations that allows the 3-D mapping of very high ...

Lightning electromagnetic emission location using arrival time differencing (LEELA): An introduction to the Met Office's next generation Very Low Frequency lightning location system

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
This paper describes the Met Office's new lightning location system LEELA. A brief overview of the upgraded hardware and geolocation algorithms is given. LEELA has improved lightning detection capabilities, especially at night. When comparing LEELA to the previous ATDnet system against ground truths LEELA has 100% storm detection efficiency within 5 km

Analysis of the Relationship Between the Morphological Characteristics of Lightning Channels and Turbulent Dynamics Based on the Localization of VHF Radiation Sources

open access: yesGeophysical Research Letters
Lightning channel morphology depends on the thunderstorm cloud charge structure, which in turn is influenced by the thunderstorm dynamics. In this paper, based on three‐dimensional radiation source localization data from the Lightning Mapping Array and ...

A new electric field mill array with each of the mill’s rotor controlled precisely by a GPS module: Equipment and initial results

open access: yesEarth and Planetary Physics
We have newly designed an electrostatic sensor, called an electric field mill (EFM), to simplify the estimation of the charge position and charge amount transferred by lightning discharges.

Proximity Proteomics Maps Candidate Cellular Uptake Pathways for Cell‐Derived Nanovesicles

open access: yesSmall Methods, EarlyView.
TurboID‐based dual‐sided proteomics compares mechanically generated cell‐derived nanovesicles with naturally secreted small extracellular vesicles. Vesicle proteomes define candidate interaction signatures, while recipient‐cell proximity labelling identifies exposure‐associated proteins.

Statistical analysis of storm electrical discharges reconstituted from a lightning mapping system, a lightning location system, and an acoustic array [PDF]

open access: yesJournal of Geophysical Research: Atmospheres, 2016
AbstractIn the framework of the European Hydrological Cycle in the Mediterranean Experiment project, a field campaign devoted to the study of electrical activity during storms took place in the south of France in 2012. An acoustic station composed of four microphones and four microbarometers was deployed within the coverage of a Lightning Mapping Array
