Ionosphere. The ionosphere (/ aɪˈɒnəˌsfɪər /) [1][2] is the ionized part of the upper atmosphere of Earth, from about 48 km (30 mi) to 965 km (600 mi) above sea level, [3] a region that includes the thermosphere and parts of the mesosphere and exosphere. The ionosphere is ionized by solar radiation.
The atmosphere of Earth is composed of a layer of gas mixture that surrounds the Earth 's planetary surface (both lands and oceans), known collectively as air, with variable quantities of suspended aerosols and particulates (which create weather features such as clouds and hazes), all retained by Earth's gravity.
Atmospheric electricity describes the electrical charges in the Earth's atmosphere (or that of another planet). The movement of charge between the Earth's surface, the atmosphere, and the ionosphere is known as the global atmospheric electrical circuit. Atmospheric electricity is an interdisciplinary topic with a long history, involving ...
This is when bubbles can form in the ionosphere. Earth’s magnetic field lines also carry charged particles free-floating in the atmosphere to two dense bands north and south of the equator that ...
Upper atmosphere is a collective term that refers to various layers of the atmosphere of the Earth above the troposphere [1] and corresponding regions of the atmospheres of other planets, and includes: The mesosphere, which on Earth lies between the altitudes of about 50 and 80 kilometres (31 and 50 mi), sometimes considered part of the "middle ...
The High-frequency Active Auroral Research Program (HAARP) is a University of Alaska Fairbanks program which researches the ionosphere – the highest, ionized part of Earth's atmosphere. The most prominent instrument at HAARP is the Ionospheric Research Instrument (IRI), a high-power radio frequency transmitter facility operating in the high ...
The Northern Lights, or aurora borealis, form when charged particles from the surface of the sun explode off and interact with the ionosphere, a high layer of our atmosphere about 100 miles above ...
The ionosphere is an ideal place to look for the telltale signs of this particular form of dark matter, the scientists explain, because we already spend a lot of time and resources doing studies ...
