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 ...
The polar cap ionosphere is directly linked to the interplanetary magnetic field carried by the solar wind. Polar cap thus provides a vantage point for the study of energy exchange between the solar wind, magnetosphere and ionosphere. CHAIN is an integral part of the Canadian Geospace Monitoring (CGSM) programme.
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.
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]
PASS (The basic steps for portable fire extinguisher use.) [6] Pull or Pin - Pull the pin at the top of the fire extinguisher (and immediately test the extinguisher). Aim - Aim the nozzle or outlet of the extinguisher at the base of the fire. Squeeze - Squeeze the handles of the extinguisher to begin discharging it.
The English Channel, [a] [1] also known as the Channel, is an arm of the Atlantic Ocean that separates Southern England from northern France. It links to the southern part of the North Sea by the Strait of Dover at its northeastern end.
The Pyrene Company Limited from their beginning in 1914, until 1971 when they became Chubb Fire Security Limited, were among the world's leaders in the manufacture of fire fighting equipment. The name Pyrene was epitomised by their famous 'pump' extinguisher which was installed on public transport, commercial and private vehicles throughout the ...
Layers of the ionosphere.The Kennelly–Heaviside layer is the E region. The Heaviside layer, [1] [2] sometimes called the Kennelly–Heaviside layer, [3] [4] named after Arthur E. Kennelly and Oliver Heaviside, is a layer of ionised gas occurring roughly between 90km and 150 km (56 and 93 mi) above the ground — one of several layers in the Earth's ionosphere.
