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 ...
Aleksandr Georgievich Loran, also known as Aleksandr Lovan or Aleksandr Lavrentyev, Alexander Laurant (Russian: Александр Георгиевич Лоран; 1849 – c. 1911) was a teacher and inventor of fire fighting foam and foam extinguishers. He lived in the Russian Empire. A modern foam fire extinguisher.
Several layers can be distinguished in the atmosphere based on characteristics such as temperature and composition, namely the troposphere, stratosphere, mesosphere, thermosphere (formally the ionosphere) and exosphere. The study of Earth's atmosphere and its processes is called atmospheric science (aerology), and includes multiple subfields ...
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. [19]
Consequently, the ionosphere consists of a rapid increase in density of free electrons, beginning at ~70 km, reaching a peak at ~300 km, and then falling off again as the atmosphere disappears entirely by ~1,000 km. Various aspects of HAARP can study all of the main layers of the ionosphere.
A fire extinguisher can be the difference between a minor house fire and the total loss of your home. However, a fire extinguisher is only as effective as its accessibility when disaster strikes ...
Dry chemical powder is used on all classes of fires. Dry chemical powder puts out the fire by coating the burning material with a thin layer of dust, thereby separating the fuel from the oxygen in the air. The powder also works to interrupt the chemical reaction of fire, so these extinguishers are extremely effective at putting out the fire.
