  2. Ionosphere - Wikipedia

    en.wikipedia.org/wiki/Ionosphere

    Relationship of the atmosphere and ionosphere. The ionosphere (/ aɪ ˈ ɒ n ə ˌ s f ɪər /) [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 ...

  3. Atmosphere of Earth - Wikipedia

    en.wikipedia.org/wiki/Atmosphere_of_Earth

    The ionosphere is a region of the atmosphere that is ionized by solar radiation. It is responsible for auroras. During daytime hours, it stretches from 50 to 1,000 km (31 to 621 mi; 160,000 to 3,280,000 ft) and includes the mesosphere, thermosphere, and parts of the exosphere.

  4. F region - Wikipedia

    en.wikipedia.org/wiki/F_region

    The F region of the ionosphere is home to the F layer of ionization, also called the Appleton–Barnett layer, after the English physicist Edward Appleton and New Zealand physicist and meteorologist Miles Barnett. As with other ionospheric sectors, 'layer' implies a concentration of plasma, while 'region' is the volume that contains the said layer.

  5. International Reference Ionosphere - Wikipedia

    en.wikipedia.org/wiki/International_Reference...

    For a specified geographic location, time, and date, IRI provides average monthly values for electron density, electron temperature and ion temperature, and the molecular composition of the ions in the range of altitudes from 50 km to 2000 km. [1] The latest standard is IRI-2012. [1] [2] A new version, IRI-2016, has since been released. [3]

  6. Atmospheric electricity - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_electricity

    The ionosphere is the inner edge of the magnetosphere and is the part of the atmosphere that is ionized by solar radiation. ( Photoionization is a physical process in which a photon is incident on an atom, ion or molecule, resulting in the ejection of one or more electrons.) [ 24 ]

  7. Upper atmosphere - Wikipedia

    en.wikipedia.org/wiki/Upper_atmosphere

    The ionosphere, an ionized portion of the upper atmosphere which includes the upper mesosphere, thermosphere, and lower exosphere and on Earth lies between the altitudes of 48 and 965 kilometres (30 and 600 mi)

    The EPA began monitoring for hydrogen fluoride, a highly toxic gas produced by lithium-ion battery fires, and for particulate matter, according to the county’s timeline.

  9. Van Allen radiation belt - Wikipedia

    en.wikipedia.org/wiki/Van_Allen_radiation_belt

    Measurements from the Van Allen Probe B's Magnetic Electron Ion Spectrometer (MagEIS) show long electron lifetimes (i.e., longer than 100 days) in the inner belt; short electron lifetimes of around one or two days are observed in the "slot" between the belts; and energy-dependent electron lifetimes of roughly five to 20 days are found in the ...
