![]() Ground wave curves around the Earth's surface for thousands of kilometers. | Signals are attenutated when the lowest regions (below 75 km in day and 90 km at night) of the ionosphere, called the D and E regions, are disturbed. Effected by solar x-rays, geomagnetic storms, electron precipitation events, ionospheric substorms, Polar Cap Absorption (PCA) events and high altitude nuclear bursts). |
