ionospheres
1
a layer in the upper atmosphere containing ions and free electrons, affecting radio communication and contributing to auroras
- The ionosphere reflects radio waves, allowing long-distance communication by bouncing signals off this atmospheric layer.
- The ionosphere is crucial for the operation of the Global Positioning System (GPS), aiding accurate location determination.
- Radio signals passing through the ionosphere experience changes in propagation due to the presence of ions and free electrons.
- The ionosphere's density varies with altitude and time, affecting the behavior of electromagnetic waves passing through it.
- Auroras, like the Northern Lights, are produced when charged particles from the Sun interact with the ionosphere.
