The Ionosphere

The ionosphere is the ionized part of Earth’s upper atmosphere that extends from about 80 to 600 km above sea level. It’s a region within the thermosphere filled with charged particles that play a crucial role in radio communication by reflecting radio waves back to Earth. It also contributes to auroras and is ionized by solar radiation. This video briefly overviews the 3 regions of the Ionosphere, how they work and how they were discovered. Do you know how the E layer got its name? Do you know what the Appleton Layer is?

Back in the 1980's I used to listen to NFL games on the U.S. Armed forces network with my radio in the U.K. I'd get the early game in, but at around 21:15 the signal would get weaker and weaker until all you could hear was static. I never knew why. . . Now I know! Thanks!!

These videos kick a$$. Great stuff

The voice over work gives me the Beyond 2000 Simon Reeve vibe. Smashing job mate.

Great work- educational. Can be useful when preparing for amateur radio tests.

[@VK3FS]

Absolutely!

FYI Appleton knew the "E" layer as the Heaviside-Kennelly layer, predicted many years before. His experiments in radio wave reflection detected three layers, which he identified as D, E and F in order to allow for the possibility that there might one day be layers detected lower than the D layer. No such layers have been found.

Another gem. Thanks for sharing.
