Live observatory / Guides

OPEN SCIENCE · SRL GUIDES

Schumann resonance, explained clearly.

These guides connect the live observatory to the underlying physics. They distinguish measured Tomsk and NOAA data from modelled nominal resonance values, so you can interpret a chart without confusing a scientific explanation with a health or mystical claim.

01 · FOUNDATION

What Is the Schumann Resonance?

Earth–ionosphere cavity physics, the 7.83 Hz fundamental, five harmonics, frequency drift and what the evidence says about biology.

02 · REFERENCE

SR1–SR5 Frequency Table

Nominal frequencies, observed ranges, wavelengths, quality factors and how to compare modes on a live chart.

03 · MEASUREMENT

How to Read a Tomsk Spectrogram

What the axes and bright bands mean, how the Tomsk SOS record is relayed, and how NOAA space weather adds context.

04 · SOURCES

Sources & Methodology

How Tomsk SOS-70, NOAA SWPC, freshness labels, missing data and modelled nominal resonance values are separated and interpreted.
