Definition of ionosphere in English Turkish dictionary

iyonosfer

iyonyuvarı

(isim) iyonosfer

(Askeri) İYONOSFER: 1. Atmosferin elektromanyetik dalgaları yansıtacak miktarda iyonların ve serbest elektronların bulunduğu 70 km ile 500 km lik kısmı. 2. Arz atmosferinin dış bir kuşağı. Güneşten veya yıldızlararası uzaydan gelen ışımalar, burada atmosfer gazlarının atom ve moleküllerini iyonlar veya elektrikle harekete getirir. İyonosferin yüksekliği zamana ve mevsime göre değişir fakat sınırının 25 ila 50 mil arasında olduğu kabul edilir. Işıma ve yansıtma özelliklerine göre çeşitli tabakalara ayrılır. Karakteristik bir olay, bazı radyo dalgalarını yansıtmasıdır

Definition of ionosphere in English English dictionary

The similar region of the atmosphere of another planet

The part of the Earth's atmosphere beginning at an altitude of about 50 kilometers (31 miles) and extending outward 500 kilometers (310 miles) or more

The region of a planetary atmosphere with a sufficient free electron density to affect radio communication Very little ionization is required: it varies between one per thousand molecules to one per 100 million molecules in different regions The bottom of the ionosphere in the Earth's atmosphere is at an altitude of about 80 kilometers during the day, rising to about 100 kilometers during the night The ionosphere starts at the top of the mesosphere (beginning of the thermosphere) and continues to about 1000 kilometers altitude

The layer of Earth's upper atmosphere that is partially ionized by solar x-rays and ultraviolet radiation and energetic particles from space

A region of charged particles in a planet's upper atmosphere; the part of the earth's atmosphere beginning at an altitude of about 400 kilometres (25 miles) and extending outward 400 kilometres (250 miles) or more

A layer of the Earth's atmosphere ranging from about 100 to 700 km above the surface in which oxygen and nitrogen are ionized by sunlight, producing free electrons

A complex atmospheric zone of ionized gases that extends between 50 and 400 miles (80 to 640 kilometers) above the earth's surface It is located between the mesosphere and the exosphere and is included as part of the thermosphere

An area of the atmosphere approximately 40 miles thick, which contains charged particles

A region of charged particles in a planet's upper atmosphere; the part of the earth's atmosphere beginning at an altitude of about 400 kilometers (25 miles) and extending outward 400 kilometers (250 miles) or more

Layers of the Earth's atmosphere located above the stratosphere from about thirty to two hundred and fifty miles above the earth's surface, and composed of rarefied gases that have been ionized by radiation from the Sun

series of concentric ionized layers forming part of the upper atmosphere of the earth from around 50 up to 600 km, where it merges with the magnetosphere; the part of the atmosphere that significantly affects propagation of radio signals on frequencies under 30 MHz

The outer layer of the Earth's atmosphere that consists of layers of ionized gas atoms

A region of charged particles in a planet's upper atmosphere; the part of the earth's atmosphere beginning at an altitude of about 400 kilometers and extending outward 400 kilometers or more

The outer layers of the Earth's atmosphere (above 50 miles from the surface of the Earth), where many of the gas atoms are ionized by high-energy extraterrestrial radiation

The region of the Earth's upper atmosphere containing a small percentage of free electrons and ions produced by photoionization of the constituents of the atmosphere by solar ultraviolet radiation at very short wavelengths Introduction to the Ionosphere

The region of the Earth's upper atmosphere containing free electrons and ions produced by ionization of the constituents of the atmosphere by solar ultraviolet radiation at very short wavelengths

The part of Earth's atmosphere containing electrically charged particles that reflect radio waves

The region of the atmosphere, extending from roughly 40 to 250 miles altitude, in which there is appreciable ionization The presence of charged particles in this region profoundly affects the propagation of long-wavelength electromagnetic radiations (radio and radar waves)

the ionosphere the part of the atmosphere which is used to help send radio waves around the Earth (ion + -sphere (as in atmosphere)). Region of the Earth's atmosphere in which the number of ions, or electrically charged particles, is large enough to affect the propagation of radio waves. The ionosphere begins at an altitude of about 30 mi (50 km) but is most distinct above about 50 mi (80 km). The ionization is caused mainly by solar radiation at X-ray and ultraviolet wavelengths. The ionosphere is responsible for the long-distance propagation, by reflection, of radio signals in the shortwave and broadcast bands

a region covering the highest layers in the Earth's atmosphere, containing an appreciable population of ions and free electrons The ions are created by sunlight ranging from the ultra-violet to x-rays In the lowest and least rarefied layer of the ionosphere, the D-layer (around 70 km or 45 miles), as soon as the Sun sets the ions and electrons recombine, but in the higher layers, collisions are so few that its ion layers last throughout the night

shortwave travel around the earth by bouncing between the earth and the ionosphere (The part of the earth's atmosphere that reflects shortwave back to the earth)

The region of Earth's atmosphere that extends from about 50 to 300 miles above the surface of the planet and is made up of multiple layers dominated by electrically charged, or ionized, atoms

The region of the Earth's upper atmosphere containing a small percentage of free electrons and ions produced by photoionization of the constituents of the atmosphere by solar ultraviolet radiation at very short wavelengths (less than 1000 angstroms) The ionosphere significantly influences radiowave propagation of frequencies less than about 30 MHz

The ionosphere consists of the layers of ionized air in the atmosphere extending from 70 kilometers to 700 kilometers and higher Depending on frequency, the ionosphere can either block radio signals completely or change the propagation speed Global navigation satellite signals are delayed as they penetrate the ionosphere This ionospheric delay can be either predicted using models, though with relatively poor accuracy, or corrected using two frequency receivers

A region in the atmosphere above 50 kilometers from the surface where relatively large concentrations of ions and free electrons exist The ionosphere is important for human communications because it re-directs AM radio transmissions This process extends the distance that radio transmissions can travel

the outer region of the Earth's atmosphere; contains a high concentration of free electrons

That part of the atmosphere that is ionised by the sun's radiation Extends upwards from about 60 km The free electrons in the ionosphere support radio wave propagation

A region of charged particles in a planet's upper atmosphere In Earth's atmosphere, the ionosphere begins at an altitude of about 25 miles and extends outward about 250

{i} part of the outer atmosphere which contains large amounts of ions and free electrons (surrounds the earth and some planets)

The part of the earths atmosphere beginning at an altitude of about 50 kilometers (31 miles) and extending outward 500 kilometers (310 miles) or more
