Total Electron Content
Total Electron Content

The Total Electron Content (TEC) is the total number of electrons present along a path between a radio transmitter and receiver.

Radiation Belts
Radiation Belts

Radiation belts are regions of enhanced populations of energetic electrons and protons surrounding the Earth in space.

Aurora
Aurora

The Aurora Borealis (Northern Lights) and Aurora Australis (Southern Lights) are the result of electrons colliding with the upper reaches of Earth’

Earth's magnetosphere

The magnetosphere is the region of space surrounding Earth where the dominant magnetic field is the magnetic field of Earth, rather than the magnet

Ionosphere

The Ionosphere, between 80 and ~600 km in the Earth’s upper atmosphere, is where solar radiation caused ionization creates a layer of electrons that can effect earth systems.

SDO-193 Image of Coronal Holes
Coronal Holes

Coronal holes appear as dark areas in the solar corona in extreme ultraviolet (EUV) and soft x-ray solar images.

Galactic Cosmic Rays
Galactic Cosmic Rays

Galactic Cosmic Rays (GCR) are the slowly varying, highly energetic background source of energetic particles that constantly bombard Earth.
