“…The results of the analysis and modelling have shown that first SR frequency increases from 7.75 Hz at minimum to about 7.95 Hz at maximum while the global mean attenuation rate at 8 Hz varies from 0.31 dB/Mm at minimum to about 0.26 dB/Mm at maximum. Recently, Koloskov et al [2013] have reported the results of long period (2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012) horizontal magnetic field SR observations conducted at Ukrainian Antarctic station "Academician Vernadsky" and shown that both the SR first mode frequency and horizontal component's intensity follow the trend in variation of solar activity. The LIS data relate to cloud formation and lightning flashes near the earth's atmosphere and are also influenced by solar activities.…”

<p>Employing a set of 3-component search coil magnetometer, Schumann resonance studies have been in progress at Agra (Geograph. lat. 27.2°N, long. 78°E), India since 01 April, 2007. We have analysed the data for two periods; first from 01 April, 2007 to 31 March, 2008 (period-I), and then from 01 March, 2011 to 29 February, 2012 (period-II) which correspond to pre and post periods of solar cycle minimum of 2008-2009. From the diurnal variation of first mode intensity and frequency, we study the seasonal variations of global thunderstorm activity, effective source distance and level of lightning during both the periods. We show that world thunderstorm activity shifts to summer in the northern hemisphere as the effective source distance approaches close to the observer, and the level of intense lightning shifts from the month of July, 2007 in period-I to August, 2011 in period-II. This is supported by Lightning Imaging Sensor (LIS) satellite data also. A possible explanation in terms of increasing solar activity is suggested.</p>

“…We used the algorithms described in (Koloskov et al, 2005;2013;2020a;Shvets et al, 2022) for SR data processing. These algorithms include finding the spectral and polarization parameters of the first three Schumann resonance modes.…”

“…Both variations of Schumann resonance parameters and the increase in ELF transient events during the eruption are presented and analyzed. We applied the data processing techniques outlined in (Koloskov et al, 2005;2013;2020a;2020b;Shvets et al, 2022) to handle the SR field and ELF transient data. These algorithms were thoroughly validated by comparing the processing results from Vernadsky and Sousy with those obtained from various ELF observation sites situated in low, mid, and high latitudes (Sátori et al, 2016;Bozóki et al, 2021;Bozóki et al, 2023) using alternative computational methods.…”

The main objective of this study is to evaluate the effectiveness of the CARISMA (Canadian Array for Realtime Investigations of Magnetic Activity) -Akademik Vernadsky station (65.25°S 64.25°W, Vernadsky) Extremely Low Frequency (ELF) induction magnetometer network as a planetary monitoring system for thunderstorm activity, with observation sites located in the Arctic and Antarctic regions, respectively. To achieve this, daily ELF records from Vernadsky and Fort Churchill (FCHU, 58.76°N 94.08°W) collected in January 2022 were processed and analyzed. For CARISMA, data from the FCHU site were used due to the better signal-to-noise ratio. The horizontal magnetic components of Schumann signals obtained at Vernadsky and FCHU underwent spectral and polarization processing. ELF transients were identified, and subsequent geolocation was performed as well. Both regular (quiet) thunderstorm activity periods and an unprecedented local amplification of lightning activity near the Hunga Tonga-Hunga Ha'apai volcano during its eruption on January 15, 2022, were studied. Throughout the quiet periods, ELF signal processing yielded similar characteristics of integral lightning activity derived from CARISMA and Vernadsky records, consistent with findings in the literature and previous investigations at the Vernadsky site. On the other hand, the analysis of Schumann spectra and ELF transients during the Tonga volcano eruption confirmed that most thunderstorms were concentrated within a relatively small area around the epicenter, validating the point source model for the global lightning center. This paper demonstrates that the CARISMA and Vernadsky magnetometer network is well-suited for establishing a global lightning activity monitoring and intense lightning geolocation system. Such a system can be employed to assess and study global temperature trends, monitor the growth of lightning activity in high latitudes, and detect terrestrial, atmospheric, and geospace disaster phenomena.

“…These should be equipped with the same calibrated receiving hardware and exploit the same processing technique. There is such a pair of facilities: the Ukrainian Antarctic Observatory "Akademik Vernadsky" (UAS; 65.25 • S and 64.24 • W) and the Norwegian observatory on Svalbard SOUSY (78.15 • N and 16.05 • E); the details can be found in [23,24].…”

Integrated Schumann Resonance Intensity as an Indicator of the Global Thunderstorm Activity

This paper addresses the accuracy of estimates for the contemporary level of global thunderstorm activity found from the synchronous records of integrated Schumann resonance (SR) intensity at two high-latitude observatories in the Northern and Southern hemispheres. The results are based on numerical simulations of electromagnetic fields in the frequency band of the global (Schumann) resonance in the Earth–ionosphere cavity characterized by a realistic conductivity profile in the middle atmosphere. The credible distribution is used for global thunderstorm activity in space and time. The paired observatory locations are considered either at the geographic poles or at Svalbard and the Antarctic Peninsula. The seasonal variations in the spatial distribution of global thunderstorms are adopted from the OTD satellite observations. The diurnal variations imply the spatial and temporal distribution of lightning strokes measured by the WWLLN network for an arbitrarily chosen date of 18 January 2022. The results obtained suggest that simultaneous records of the integrated SR intensity at Svalbard and in Antarctica provide errors below 3% in the diurnal variations of global thunderstorm activity with a temporal resolution of 10 min. The seasonal changes in global thunderstorm intensity are estimated with an error of ~10%. Since the level of global thunderstorm activity varies by a factor of two on the both time scales, the estimates confirm the appropriate accuracy of the estimate of thunderstorm activity from the concurrent measurements at the high-latitude SR observatories in the Arctic and Antarctic.
