Schumann Resonance Today is an educational monitoring website focused on Earth–ionosphere resonances and related space-weather information. Its main feature is a recent Schumann resonance spectrogram from Tomsk, Russia, presented with a source timestamp, freshness status and guidance for interpreting the data. The site explains that the chart shows measured signal power across frequency and time, not a single, fixed planetary vibration.

Visitors can explore companion plots for resonant mode frequencies, signal amplitudes and quality factors, alongside electromagnetic background, magnetic component and ionosphere panels. The site also provides illustrated guidance on reading chart axes, bands, gaps, colors and saturation, and explains how lightning, ionospheric changes, measurement conditions and local interference can affect observations.

Additional resources include science explanations and citations, source and methodology documentation, and current solar and space-weather imagery. The site links to related lightning, VLF and ELF, aurora and cosmic-ray monitoring resources for context. It emphasizes data freshness, measurement quality and careful interpretation, cautioning that the charts do not establish health, mood or consciousness effects.
