Relative signal power of the F1 modeSignal power driven by global thunderstorm output. Follows a diurnal cycle as Africa, South America, and Asia rotate through peak lightning activity.
Q-FactorNominal
0.0
Nominal: 4 or above · higher = cleanerMeasures cavity energy retention per oscillation. Drops during solar flares due to increased ionospheric absorption. Higher values signal clean resonance.

Background

Schumann resonances are peaks in the extremely low frequency (ELF) electromagnetic spectrum, generated by the approximately 2,000 thunderstorms continuously active around the globe. Lightning discharges excite the natural waveguide formed between the conducting Earth surface and the ionosphere.

Predicted by physicist Winfried Otto Schumann in 1952 and experimentally confirmed in 1954, these resonances serve as a tool for studying global lightning activity, ionospheric variability, solar-terrestrial coupling, and as a climate change indicator. This dashboard provides near-real-time spectrogram data refreshing every two minutes.
