06 March 2021. How To Read The Schumann resonance Spectrogram Properly; Based- on standard, accepted engineering, technical perspective.
** **
The Spectroscope is the full-color visual representation of the Schumann resonances.
It is a composite, which is plotted in full-colour, based upon the information received from the reporting dependencies. It is this fun, yet quixotic 'visual aid', is most often used alone, without the necessary reporting dependencies, which ultimately give it the meaning.
It is this solitary portion of the SR reports, which just-about-everyone who is using this, calls "The Schumann."
The Schumann resonances (SR) are a set of spectrum peaks in the extremely low frequency (ELF) portion of the Earth's electromagnetic field spectrum.
Schumann resonances are global electromagnetic resonances, generated and excited by lightning discharges in the cavity formed by the Earth's surface and the ionosphere.
The purpose of this essay is to assist people who are interested in this subject, to better understand what they are actually looking-at when they view the plotted Spectrographic composite, colloquially called "The Schumann."

Orientation.
We start with an overview.
On the left side of the graph is the resonance frequency, which starts at 0 in the top left corner. From there moving downwards, the numbers increase.
Running along the bottom of the graph is the measurement of Time.
There are two sets of clocks. The larger, bottom numbers are UTC.
Above this is local time.
The Spectrogram is plotted from the reporting 12 dependencies, of Amplitude (Modes 1-4) ; Quality (Modes 1-4) ; Frequency (Modes 1-4); upon the Dark Blue coloured "canvas."
Dark blue would be our theoretical "at rest state."
(Which we theoretically return back to. It might be considered like an "elastic", or a medium which is under a certain tension, therefore always in motion to or from that dark blue background "at rest", or balance point.)
Upon this the twelve dependencies use actual light to plot a tapestry of patterns and codes. Because the atmosphere, which includes all the way out into the magnetosphere, is elastic in this sense, this is what essentially creates this "weaving" pattern of sheparding these EM waves around the "waveguide" of the Earth-Ionosphere 'corridor.'
At rest state of "fair weather", is our theoretical "zero point"; which starts as a dark blue (Navy)-coloured background, which is as above-stated an interactive canvas.
Upon this canvas gets reported with, or plotted by the information of the dependencies.
This is the actual raw data which is graphed by the line graphs of 4 individual colours.
I am referring to these 4 colours, which correspond to the 4 modes, as our pallet of "primary colours." (Technically, White is not a colour, but blue is.
We essentially have 4 colours as our primary pallet.)
When the literature refers to Modes, this relates to the type of internal copper windings (based upon the number of turns, of the size and cross section of wire, etc.), which allow for a certain known range of signals to be detected.
This band of signalsis in the lowest end of low frequency radio waves, which encircle the globe; primarily due to lightning discharges.

4 Modes Of Reception.
A Mode is essentially a "band", or bandwidth of measurement, within the EMF spectrum.
In this case, ELF is broken-up into 4 segments, or modes.
What Is The ELF portion of the spectrum?
This is a bit confusing, relative to the Schumann resonances.
"Schumann resonances are the principal background in the part of the electromagnetic spectrum[2] from 3 Hz through 60 Hz,[3] and appear as distinct peaks at extremely low frequencies (ELF) around 7.83 Hz (fundamental),[4] 14.3, 20.8, 27.3 and 33.8 Hz.[5]
"Extremely low frequency (ELF) is the ITU designation[1] for electromagnetic radiation (radio waves) with frequencies from 3 to 30 Hz, and corresponding wavelengths of 100,000 to 10,000 kilometers, respectively.[2][3]
"ELF radio waves are generated by lightning and natural disturbances in Earth's magnetic field, so they are a subject of research by atmospheric scientists. In atmospheric science, an alternative definition is usually given, from 3 Hz to 3 kHz.[4][5]
"In the related magnetosphere science, the lower frequency electromagnetic oscillations (pulsations occurring below ~3 Hz) are considered to lie in the ULF range, which is thus also defined differently from the ITU radio bands.
(--Wikipedia.org)
There are numerous ways frequency bands have been designated. The International Telecommunications Union designates bands as listed in the table below. Frequencies as designated by the International Telecommunications Union:
Band: Extremely low frequency (ELF) ; Propagation Frequency: 3 Hz-30 Hz ; Wavelength: 10^8m-10^7m .
Band: Super low frequency (SLF) ; Propagation Frequency : 30 Hz-300 Hz ; Wavelength: 10^7m-10^6m .
Band: Ultra low frequency (ULF) ; Propagation Frequency : 300 Hz-3 KHz ; Wavelength: 10^6m-10^5m

The Twelve Dependencies
This next section explaining the use of the Modes is difficult without numbers and specific technical data.
It's necessary, yet these specifics are not the immediate concerm of this basic summary.
To balance the need for some technical/specific data with overall readability for someone without math skills, is necessary to understand the basic function of the Modes.
We see the Modes as bandwidths, separations (similar to octaves) of the entire spectrum.
In otherwords, it is the means of breaking-down the entire spectrum of EMF waves, which span a wide range of ELF radio waves
White is Mode 1. This correlates to the highest layer of the ionosphere, furthest away from the planet. Highest frequency, of the low-range energy where the resonances reside.
Yellow is Mode 2, which measures a lower frequency range, or bandwith, than the White Mode.
Red is Mode 3, which measures successively lower range of bandwidth than Yellow.
Green is Mode 4, the lowest frequency, but largest in wavelength, between 10-100,000 Km in wavelength sizes.

Plotting The Spectrograph
Due to the abilities of the antennae to pick-up only certain signals, these colours are going to also appear in certain recognizable patterns, based-upon the type of signal; whether it is more electric, or more magnetic.
For example, the bright green shows up largely as bands, due to the fact that it is exhibiting the characteristics of the magnetic waves.
Depending on where and how the EMF signal interacts with the antennae, this is the type of mark which is going to be plotted on the spectrograph, effectively.
In other words, white, and yellow frequently, appear as spikes, or vertical lines, due to the high content of electric charge, and the fact that this is how the antennae pick-up Amplitude/charge/electrics.
White and Yellow Modes are more heavy in electric content.
Red and Green modes measure the layers closer to Earth.
Green Measures the layer of emf waves which occupy the space between Earth and the lowest layer of the ionosphere. Ultimately, the ilonosphere acts as a filter of sorts, which forces the bouncing, or return characteristics of the wavious wavelengths are.
Because the Green is high in magnetic content, the green-based colours are going to be magnetic, and display horizontally, to reflect the orientation of the reporting dependencies, Quality. We see an "upright", or vertical signal in Quality in the line graph, but the full color spectrograph shows it much better, the orientation of the magnetics, basically as "flat."
The colours teal, aqua, turquois, "indiglow" are not actually in the "Green family", despite what your colour theory may tell you. They are...but not really. These are a product of the interaction with the background of Modes 1, and 2, the white and yellow.
White and yellow is top going down, as it were, into the otherwise calm background state of rest of the Dark Blue.
Going upwards from rest into the bottom of the modes, due to heavy magnetics, the colouration goes from dark blue into Green. This is how we know that the bright teal and turquoise is a signal moving from top (high charge), downwards into the "at rest state."
Red and Yellow make orange, pumpkin, rust,; when mixed with white we get coral, or pink. These indicate a mid-grade electronics, fairly balanced with magnetics.
This is why orange and rust colours seem to "float in the air" of the chart, because it is actually "floating" somewhat.

Introducing The Antenna
On the subject of the receiving antennas for the data, I have posted many times in The Schumann Resonances harmonics group highlighting the technology and workings of the antennae used to collect the data.
For our purposes here, we need to understand a few basic concepts on how the signals are measured.
There are a few different type of antennae designs, yet the principle remain consistent, based on the following principle: The Electric portion of the signal transverses, rolls, or propagates vertically; while the magnetic portion of the signal travells horizontally, which is to say "hugging the ground."
Generally there is a ball on a "tower" which measures the Amplitude, or the electric portion. This is a dipole antenna for measuring the Amplitude.
Each antenna Mode reports: Amplitude, Quality, Frequency.
The antenna is recording a 3 dimensional configuration This is set-upon the base which measures the magnetics, or Quality, along two separate axes, 90 degrees apart; these are North-South / East-West.
The heart of the antennae is the induction coil which is wrapped around a magnetically permeable material.
The coil senses a EMF signal which is within the range of receptivity, based upon the structure of the internal windings.
The signal activates, initiates "movement" along the coil, producing a "report", or a line in the reporting dependency.
Essentially, there are 2 induction magnets: for N-S, and one for E-W.
The spectrograph is showing a 3 dimensional, spherical, construction, on a plane surface.
The ELF frequency range, as stated by Volland in Handbook of atmospheric electrodynamics, 1995, covers a frequency range from 3-60 hertz.
A Hertz is a unit of frequency, which is measuring peak-to-peak amount within the time period of one second.
As the frequency, wave to wave height increases, the length decreases inversely.
