[BC] Your friend, the Ionosphere

[RichardBJohnson at comcast.net]

Funny --but,. Why don't you give him the answers he seeks?

The suns rays contain a lot of high frequency wavelengths,
light waves even beyond ultraviolet. The sun also floods the
earth with high velocity atomic particles called the solar wind.

When the upper atmosphere captures some of this energy,
it becomes activated, "Ionized," which means that its constituents
are disassociated into charged particles. These charged particles
will eventually recombine as a continuous process. However,
they reflect, and sometimes duct radio waves. There are
several layers of charged particles, called "D->F" layers, plus
a grand outer layer called the Kennelly-Heaviside Layer.

See

for more interesting information.


Cosmic rays are something else. There are so many kinds of
cosmic rays that you need to identify each kind. See

http://en.wikipedia.org/wiki/Cosmic_Rays

There are some that are not even attenuated by the earth,
to say nothing about the ionosphere!
