Description
Extremely Low Frequency (ELF) electromagnetic waves are considered a potential source of noise for GW interferometers. Due to deep ground penetration of such waves the Einstein Telescope will be also potentially a subject to such source of noise. A possible influence of ELF waves in the Schumann resonance range (7-50 Hz) was widely studied for the LVK detectors. Currently we turned our attention to possible role of (strong) thunderstorm lightning generated ELF impulses dominating the electromagnetic noise in hundreds Hz frequencies. Basing on our recent studies of the day and night ELF impulse propagation we manage to consider such spectral component consisting of individual impulses generated by the global thunderstorm activity at the detector site. At the conference we intend to present a recent progress in the study.
The study is carried out within the Krakow ELF Group - https://www.oa.uj.edu.pl/elf/index.html .
