Balloons cannot reach it because the air is too thin, but satellites cannot orbit there because the air is too thick. Hence, most experiments on the ionosphere give only small pieces of information. HAARP approaches the study of the ionosphere by following in the footsteps of an ionospheric heater called EISCAT near Tromsø, Norway. There ...
The basic concept of a global circuit is that through the balance of thunderstorms and fair weather, the atmosphere is subject to a continual and substantial electrical current. Principally, thunderstorms throughout the world carry negative charges to the ground, which is then discharged gradually through the air away from the storms, in ...
The Weather Underground was a far-left Marxist militant organization first active in 1969, founded on the Ann Arbor campus of the University of Michigan. [2] [page needed] Originally known as the Weathermen, or simply Weatherman, the group was organized as a faction of Students for a Democratic Society (SDS) national leadership. [3]
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 ...
Scientists studying the zone between Earth’s atmosphere and space have spotted unusual X- and C-shaped features that could thwart signals that keep our planet running smoothly.
EUV was a 1-dimension limb imager designed to observe height and density of the daytime ionosphere by detecting the glow of oxygen ions and other species at wavelengths between 55 and 85 nm. FUV was a 2-dimension imager that observes the limb and below at 135 and 155 nm, where bright emissions of atomic oxygen and molecular nitrogen are found.
As a household staple in the '90s and early 2000s, AOL became a go-to as a popular song reference, forever ingraining the internet pioneer in pop culture and our ears, alike.
The F-region is the highest region of the ionosphere. Consisting of the F1 and F2 layers, its distance above the Earth's surface is approximately 200–500 km. [7] The duration of these storms are around a day and reoccur every approximately 27.3 days. [6] Most ionospheric abnormalities occur in the F2 and E layers of the ionosphere.
