Relating to the ionosphere, which is a part of the Earth's atmosphere that contains a high concentration of ions and free electrons and is important for radio communication.
The ionospheric conditions can affect satellite communications and GPS signals.
Ionospheric → It is formed from "ion" (from Greek "ion", meaning going) and "spheric" (from Greek "sphaira", meaning sphere). The word refers to the region of the Earth's atmosphere that contains ions and free electrons, which is shaped like a sphere.
Think of 'ions' as particles that are 'going' and 'spheric' as relating to a sphere — this helps you remember that 'ionospheric' refers to the spherical region of the atmosphere filled with ions.
