Spectrograms and frequencies of the first mode of Schumann Resonance according to multi-position monitoring parformed at the Ukrainian Antarctic Station (2002-2020) and at the Arctic SOUSY facility (2013-2020)

This dataset contains the processed data used for the publication: ELECTROMAGNETIC SEASONS IN SCHUMANN RESONANCE RECORDS. The dataset contains the daily spectrograms and frequensies of first mode of Schumann Resonance (derived for North-South and East-West magnetic components) of ELF signals recorded at the Ukrainian “Akademik Vernadsky” Antarctic station (65.25° N and 64.25° W) 2002-2020, and at SOUSY Arctic facility (Svalbard 78.15° N and 16.05° E) 2013-2020.
