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]
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 ...
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.
Although the research facilities need to have powerful transmitters, the power flux in the ionosphere for the most powerful facility (HAARP) is below 0.03 W/m 2. [2] This gives an energy density in the ionosphere that is less than 1/100 of the thermal energy density of the ionospheric plasma itself. [1]
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.
In February 2010, Weather Underground launched FullScreenWeather.com (now a redirect to weather.com), a full screen weather Web tool with integrated mapping and mobile device use in mind. On July 2, 2012, The Weather Channel announced that it would acquire Weather Underground, which would become operated as part of The Weather Channel Companies ...
