Measurement

Schumann Live

Current readiness of the GeoLira Schumann Live measurement chain. Live values appear only after the production ELF station, calibration and baseline satisfy the declared quality contract.

Current readiness of the GeoLira Schumann Live measurement chain. Live values appear only after the production ELF station, calibration and baseline satisfy the declared quality contract.

Near Live exposes relative activity with explicit provenance

The current Schumann view uses an approved public JSON API whose upstream source refreshes on a minute-class cadence. The main relative activity score uses a 0-100 scale and is derived analysis, not physical amplitude. SR1 is accepted as a measurement only when the source explicitly marks it Measured and supplies an in-range numeric value.

Freshness is a hard requirement for Live

GeoLira warns after 10 minutes and treats the record as hard stale after 20 minutes. Historical storage may retain the last record, but after hard expiry it cannot be presented as current Live. Missing measurement is not filled with a nominal resonance frequency simply to keep a number on screen.

Nominal frequencies are not measurements

Reference values for SR2-SR5 or numbers known from literature are not ingested as current measurements when the source did not actually measure them. Near Live also does not grant rights to redistribute third-party spectrogram images. The interface distinguishes relative activity, explicitly measured SR1 and future data from a certified first-party station.
