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.
Dec 10, 2019 · The ionosphere stretches roughly 50 to 400 miles above Earth's surface, right at the edge of space. Along with the neutral upper atmosphere, the ionosphere forms the boundary between Earth's lower atmosphere — where we live and breathe — and the vacuum of space.

The Ionosphere. Regions of the ionosphere, showing the D, E, and F layers. UCAR/Randy Russell. Earth's atmosphere contains a series of regions that have a relatively large number of electrically charged atoms and molecules. As a group, these regions are collectively called the ionosphere.
Feb 8, 2021 · A dense layer of molecules and electrically charged particles, called the ionosphere, hangs in the Earth's upper atmosphere starting at about 35 miles (60 kilometers) above the planet's surface...
Jun 13, 2024 · The ionosphere is a very active part of the atmosphere, and it grows and shrinks depending on the energy it absorbs from the Sun. The name ionosphere comes from the fact that gases in these layers are excited by solar radiation to form ions, which have an electrical charge.
Ionosphere and magnetosphere, regions of Earth’s atmosphere in which the number of electrically charged particles—ions and electrons—are large enough to affect the propagation of radio waves. The charged particles are created by the action of extraterrestrial radiation (mainly from the Sun) on.
Dec 14, 2016 · Scientists from NASA and three universities have presented new discoveries about the way heat and energy move and manifest in the ionosphere, a region of Earth’s atmosphere that reacts to changes from both space above and Earth below.
The Ionosphere is part of Earth’s upper atmosphere, between 80 and about 600 km where Extreme UltraViolet (EUV) and x-ray solar radiation ionizes the atoms and molecules thus creating a layer of electrons.
The Earth's Ionosphere Overview • Nighttime • Daytime • Sunrise and Sunset Effects • Solar Flare • Lightning • Sample Data. Overview. The ionosphere is defined as the layer of the Earth's atmosphere that is ionized by solar and cosmic radiation.
Jul 29, 2013 · The ionosphere Dynamics of the ionosphere The important equations for ions (number density n i) and electrons (number density n e) in the ionosphere are the continuity equations: where q is the production rate per unit volume and l is the loss rate per unit volume; and the momentum equations: Where E is the electric field, B is magnetic ...
