| A major role of the atmosphere was to filter out the ionising radiation from the sun by ionising the high atmosphere and forming the ionosphere. |
| The X rays from the flare bombarded the Earth's atmosphere almost instantly, cooking the ionosphere and producing a surge of electric currents. |
| Other satellites had communications problems when the excited ionosphere interfered with radio signals sent to and from the ground. |
| The burst of gamma rays and X-rays even disturbed the Earth's ionosphere, causing a sudden disruption in some radio communications. |
| This results in a powerful electric field between the cloud tops and the ionosphere, the outer layer of Earth's atmosphere. |
| The ionosphere is the layer extending from about 80 km to the outer reaches of the atmosphere that includes charged particles. |
