Abstract We present the Hylaty geophysical station, a high‐sensitivity and low‐noise facility for extremely low frequency (ELF, 0.03–300 Hz) electromagnetic field measurements, which enables variety of climatological research related to atmospheric, ionospheric, magnetospheric, space weather physics. The first systematic observations ELF fields at Jagiellonian University were undertaken in 1994. At beginning measurements carried out sporadically, during expeditions sparsely populated areas...
Correlated magnetic noise from Schumann resonances threatens to contaminate the observation of a stochastic gravitational-wave background in interferometric detectors. In previous work, we reported on first effort eliminate global correlated using Wiener filtering, demonstrating as much factor two reduction coherence between magnetometers different continents. this present results dedicated magnetometer measurements at Virgo and KAGRA sites, which are for subtraction data detector sites. We...
Abstract We present an extraordinary case of sprites in rapid succession—four sprite clusters only 400 ms—followed by a secondary jet. Simultaneous ELF and optical observations, as well lightning data, enabled us to thoroughly document this unique event. Locations the transient luminous events (TLEs) were triangulated using video recordings from Nydek (Czech Republic) Sopron (Hungary). found that displaced up 70 km their parent lightning. The current moment waveform charge changes associated...
In the extremely low frequency (ELF) range, space between ground and ionosphere forms a spherical waveguide. When studying ELF radio-wave propagation on Earth using analytical models, it is commonly assumed that has perfect conductivity. some planetary applications, conductivity so significant influence in range to be included model.

The main natural source ELF radio waves is lightning. analyzed 1000 atmospheric discharges at distances up to 5000 km from receiver. We identified most important factors influencing angle arrival: deviation propagating through day‐night terminator zone and signal‐to‐noise ratio resulting local...
Asymmetric resonance curves are observed in various systems occurring nature. The reason for such a shape of the is an interaction standing waves field resonator with traveling which transmit energy from sources to resonator. This behavior can be strongly damped electromagnetic resonators. ELF wave propagation inside Earth‐ionosphere cavity good example simultaneous occurrence and transmission phenomena. In this paper we show that component depends on attenuation rate observer‐source...

Gigantic jets have only been so far few occasions, and there is still relatively little known about them. In order to analyze signal we developed new technique, which makes it possible obtain actual lightning discharges associated with eliminating from effects both impulse...
Abstract The importance of lightning has long been recognized from the point view climate‐related phenomena. However, detailed investigation on global scales is currently hindered by incomplete and spatially uneven detection efficiency ground‐based networks restricted spatio‐temporal coverage satellite observations. We are developing different methods for investigating activity based Schumann resonance (SR) measurements. SRs electromagnetic resonances Earth‐ionosphere cavity maintained...

Our approach is Schumann resonance (SR) measurements, which apply as an example to thunderstorms Africa. By solving inverse problem, using SR power spectrum templates derived analytically, calculate distances most powerful centers and simplified 1‐D lightning...
Abstract A spherical cavity between Earth and the lower ionosphere forms a global resonator for Extremely Low Frequency electromagnetic waves. Constant thunderstorm activity leads to formation of resonance field in cavity, known as Schumann resonance.

Terrestrial gamma‐ray flashes (TGFs) were registered the first time by NASA's Compton Gamma Ray Observatory. The physical mechanism of TGF generation is not fully known, but there a consensus among researchers that radiation produced bremsstrahlung relativistic electrons in thunderstorm regions atmosphere. Therefore, TGFs have been linked to positive‐polarity intracloud lightning discharges, strong positive cloud‐to‐ground discharges or upward from thundercloud top. currently operating Fermi...
