Atmospheric Conditions, Electric Fields, and Thunderstorm Ground Enhancements at Aragats
A. Chilingarian, N. Manukyan, Q. Piliposyan
The Aragats High-Altitude Research Station (3200 m a.s.l.) combines meteorological, atmospheric electric, and particle flux measurements, providing a unique setting for investigati…
Runaway processes in the upper and lower atmosphere: a change of paradigm
A. Chilingarian
Relativistic Runaway Electron Avalanches (RREA) are central to understanding a spectrum of high-energy atmospheric phenomena, including Terrestrial Gamma-ray Flashes (TGFs), Thunde…
Energy Spectra of Secondary Particles Induced by Solar Energetic Proton Events and Magnetospheric Effects
A. Chilingarian
We investigate the energy spectra of secondary cosmic ray particles associated with two distinct solar events: the magnetospheric effect (ME) of 5 November 2023 and ground-level en…
Wind-induced Natural Gamma Radiation
A. Chilingarian, B. Sargsyan, D. Aslanyan +1
During the extreme winter storms of 2024-2025 at Aragats, natural gamma radiation (NGR) increased by more than 1000%, with fluence reaching 2*10^7 gammas/cm^2 over 10 hours and a c…
Extreme thunderstorm ground enhancements registered on Aragats in 2023
A. Chilingarian, B. Sargsyan, T. Karapetyan +4
In 2023, a series of intense Thunderstorm Ground Enhancements (TGEs) were recorded on Mount Aragats in Armenia, with five events exceeding the fair-weather cosmic ray flux by more…
