Measurements with Angular Sensitive Electric Field Mill in Thunderstorms

Martin Kákona, Jakub Kákona, Roman V. Dvorak, Iva Ambrožová et autres

Abstract Electric Field Mills (EFMs) are critical tools in atmospheric sciences for measuring electric fields within thunderstorms. Traditional EFMs primarily record field magnitudes and often lack the precise temporal resolution and directionality necessary for in-depth storm analysis. Our research introduces THUNDERMILL01, an …

BIOSPHERE measurement campaign from January 2024 to March 2024 and in May 2024: Effects of the solar events on the radiation belts, UV radiation and ozone in the atmosphere

Viviane Pierrard, David Bolsée, Alexandre Winant, Amer Al-Qaaod et autres

In this work, we analyzed simultaneous observations of solar particles and solar electromagnetic ultraviolet (UV) radiation during solar events from January 2024 to May 2024. Measurement campaigns to study the effects of space radiation on the terrestrial atmosphere were conducted in the …

First Reported Detection of a Winter Continental Gamma-Ray Glow in Europe

Jakub Šlegl, Zbyněk Sokol, Petr Pešice, Ronald Langer et autres

Abstract. This study presents the first-ever detection of a winter continental gamma-ray glow in Central Europe, observed during a rare winter thunderstorm on Milešovka hill, Czechia. Unlike typical gamma-ray glow events, which are usually linked to significant electric field increases, this unique …

First observation of significant long-lasting Thunderstorm Ground Enhancements on the Milešovka peak (altitude 837 m) in Czechia

Ivana Kolmašová, Ondřej Santolík, Ondřej Ploc, Ronald Langer et autres

Bursts of gamma rays observed on the Earth’s surface – so called Thunderstorm Ground Enhancements (TGE) were detected by a plastic scintillator (disassembled from the particle detector SEVAN) located in the observatory building on the Milešovka peak (50.6N, 13.9E, altitude 837 m) …

Radiation enhancements at Lomnický peak during thunderstorms

Jaroslav Chum, K. Kudela, Marek Kollárik, Ronald Langer et autres

A simultaneous measurement of secondary cosmic rays (CRs) by the detector system SEVAN (Space Environmental Viewing and Analysis Network) and of atmospheric electric field by EFM100 sensor at high mountain peak, Lomnický štít, altitude 2634 m asl, is presented. More than 20 …
