“…The long-term monitoring of the Schumann phenomenon has recently drawn attention, not least from the space-geophysics community [1][2][3]. SR measurements and analysis provide information on the planetary thunderstorm activities, the properties of lower ionosphere layers, the Earth surface and atmosphere temperature variations, and the properties of earthquakes as well as on the studies of other celestial bodies [4][5][6][7][8][9]. Consequently, increased interest has been shown by the scientific community on the methods and techniques employed in SR experimental detection.…”

Schumann resonance oscillation detection is a complex procedure which requires customized and high-quality measurement systems. The primary objective of this work was to design and implement a stand-alone, portable, and low-cost receiver able to measure as much Schumann resonance harmonics as possible. Design, as well as detailed analysis of the efficient induction coil magnetic antenna and the low-noise amplifying-filtering chain, is presented. The detection system includes two coils back to back, resulting in a total coil length of 60 cm. The filtering and amplification chain exhibits an experimentally measured total passband gain equal to 112 dB at 10 Hz and as low as 2.88 nV/√Hz equivalent input noise. In order to validate the new portable ELF Schumann resonance detection and monitoring system, we took measurements at various spots "relatively" free from man-made electromagnetic pollution. Results have shown very clear Schumann resonance peaks for the first six modes with 10-min acquisition time.

“…It takes minutes to obtain the results for various environmental models, whereas with numerical modeling it takes days. The potential of the method has been presented in previous publications (Kulak et al 2013;Kozakiewicz et al 2015). Using this method, we found the relationship between individual properties of the Martian ground (e.g.…”

“…On the basis of the measured ELF propagation parameters or the Schumann resonance parameters, the structure of the ground can be estimated by finding inverse solutions of Maxwell's equations in non-uniform mediums. To accomplish such an investigation, an analytical method has been developed (Kulak et al 2013), and used to investigate the waveguide properties that could be acquired from the impulse waveform measurements and the SR investigation (Kulak et al 2013;Kozakiewicz et al 2015). The developed method is computationally efficient.…”

Natural electromagnetic (EM) signals of extremely low frequencies (ELF, 3 Hz-3 kHz) can be used to study many of the electromagnetic processes and properties occurring in the Martian environment. Sources of these signals, related to electrical activity in the atmosphere, are very significant since they can influence radio wave propagation on the planet, the atmospheric composition, and the ionospheric structure. In addition, such EM signals can be employed in many purposes such as: surveying the subsurface of Mars or studying the impact of the space weather on the Martian ionosphere. As ELF waves propagate on very long distances, it is possible to explore properties of the entire planet using single-station recordings. In this study, we propose an experiment that allows measuring ELF signals from the Martian surface. Such measurements can be used for detection of electric discharges in the atmosphere and water reservoirs in the planetary subsurface.

“…In addition, a layer created by meteoric ablation at 80–90 km of altitude is known to be present [ Molina‐Cuberos et al , ; Withers et al , ]. Several works have studied the properties of the SR on Mars [ Sukhorukov , ; Pechony and Price , ; Molina‐Cuberos et al , ; Yang et al , ; Soriano et al , ; Kozakiewicz et al , ]. However, the effects of the changing day‐night conditions and dust were not considered by these previous studies.…”

Schumann resonances are standing waves that oscillate in the electromagnetic cavity formed between the conducting lower ionosphere and the surface of the planet. They have been measured in situ only on Earth and Titan, although they are believed to exist on other planets like Mars. We report numerical simulations of the Martian electromagnetic cavity, accounting for the day‐night asymmetry and different dust scenarios. It has been found that the resonances are more energetic on the nightside, the first resonance is expected to be 9–14 Hz depending on the dust activity and to have low quality factors (Q≃2). This work serves as an input for the upcoming Exomars surface platform (launch 2020), who will attempt to measure them for the first time.
