ionosphere
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
