Modeling Schumann resonances with schupy [PDF]
Journal of Atmospheric and Solar-Terrestrial Physics, 2019 Abstract Schupy is an open-source python package aimed at modeling and analyzing Schumann resonances (SRs), the global electromagnetic resonances of the Earth-ionosphere cavity resonator in the lowest part of the extremely low frequency band ( 100 Hz).

DISTURBANCES OF LOWER IONOSPHERE ABOVE CENTER OF EARTHQUAKE AND ANOMALY IN THE GLOBAL ELECTROMAGNETIC RESONANCE SIGNAL PART 1. MODELS OF IONOSPHERE [PDF]
Радиофизика и электроника, 2015 We model an effect on the Schumann resonance signal recorded in Japan of the ionosphere non-uniformity centered above the earthquake at Taiwan. Changes in the resonance spectrum occur due to interference of the direct radio wave with one reflected from ...

Gigantism in unique biogenic magnetite at the Paleocene-Eocene Thermal Maximum [PDF]
, 2008 We report the discovery of exceptionally large biogenic magnetite crystals in clay-rich sediments spanning the Paleocene-Eocene Thermal Maximum (PETM) in a borehole at Ancora, New Jersey. Aside from previously-described abundant bacterial magnetofossils,

Model modifications in Schumann resonance intensity caused by a localized ionosphere disturbance over the earthquake epicenter [PDF]
Annales Geophysicae, 2006 This paper is a further extension of our latest observations and modeling by Hayakawa et al. (2005a), in which we discovered the anomalous behavior of Schumann resonance observed in Japan, in possible association with the Chi-chi earthquake in ...
