Explore real Schumann-band spectra, identified F1-F4 resonance modes, source provenance and the current GeoLira Live readiness state. Historical reference measurements are clearly separated from live data and from authored interpretation.
Schumann resonance is a set of ELF cavity modes
The global Earth-ionosphere cavity supports several electromagnetic resonances excited mainly by lightning. The first mode is usually near 7.8 Hz and higher modes occur above it. Frequency, amplitude, linewidth and Q are separate parameters describing different properties of the spectrum.
GeoLira separates external source data from first-party measurement
Current Near Live may provide a relative activity score and SR1 only when the API explicitly marks that value as Measured. This does not certify a complete physical set of F1-F4, amplitude and Q. A future first-party measurement requires an ELF station, calibration, a noise baseline, heartbeat monitoring and separate certification.
The spectrum is not a health or consciousness meter
Resonance changes have geophysical and electromagnetic meaning, but by themselves they cannot diagnose health, mood or consciousness. A relative 0-100 index is not a frequency in Hz. Interpretation should begin with evidence class, unit, station, quality and observation time.
