stratosphere - the upper portion of the atmosphere (approximately 11 km to 50 km above the surface of the earth).
Stratosphere - The thermal atmospheric region of the atmosphere between the troposphere and the mesosphere.
Stratosphere. The part of the atmosphere directly above the troposphere. See Atmosphere.
Thermal. Thermal properties are dependent on temperature; they are related to, or caused by heat.
Stratosphere: The layer of the atmosphere between about 10 and 40 km above the Earth's surface within which temperatures rise with altitude. The stratosphere contains 90 per cent of the atmosphere's ozone (O3).
Stratosphere - Part of the atmosphere, the gases that encircle the Earth. The stratosphere is a layer of the atmosphere 9 to 31 miles above the Earth.
stratosphere
The layer of the earth's atmosphere that extends from approximately 11 km to 50 km above the earth's surface.

Stratosphere: The layer of the Earth's atmosphere above the troposphere and below the mesosphere. It extends between 10 and 30 miles above the Earth's surface and contains the ozone layer in its lower portion.

Stratosphere The atmosphere from approximately 12 km to 70 km. The temperature of the atmosphere increases in this region.
Stream based standards See receiving water quality standards.
The stratosphere and stratopause stretch above the troposphere to a height of 50 km.
Halon Bromine-containing compounds with long atmospheric lifetimes whose breakdown in the stratosphere causes depletion of ozone. Halons are used in firefighting.
In the stratosphere, it serves to absorb many harmful solar UV rays. More Information.
P
Polar Stratospheric Clouds (PSC's) The medium in which reservior chlorine comounds are converted into ozone-destroying chlorine radicals.
Ozone (O3)- Found in two layers of the atmosphere, the stratosphere and the troposphere.
The ozone in the stratosphere is more stable than the tropospheric ozone and forms an ozone layer roughly between 15 and 50 km above the earth.
The highest levels of ozone in the atmosphere are in the stratosphere, in a region also known as the ozone layer.
The phenomena which shows a steady decline in the total volume of ozone in the Earth's protective stratosphere or ozone layer, which filters the sun's harmful UVB rays.
The highest natural concentration of ozone (approximately 10 parts per million by volume) occurs in the stratosphere at approximately 25 km above Earth.
Ozone (O3) - Ozone is a greenhouse gas present in the stratosphere and the troposphere. In the stratosphere, ozone provides a protective layer shielding the earth from harmful ultraviolet radiation.
One of the strongest predictions of the global warming theory is that the stratosphere should cool.
Small concentrations of ozone occur naturally in the stratosphere, which is part of the Earth's upper atmosphere.
Ozone (O3)
a naturally occurring unstable form of oxygen; attenuates harmful ultraviolet light in the stratosphere; a pollutant in the atmosphere at ground level; a powerful oxidising agent and disinfectant ...
This destruction of ozone is caused by the breakdown of certain chlorine and/or bromine containing compounds (chlorofluorocarbons or halons), which break down when they reach the stratosphere and then catalytically destroy ozone molecules.
In addition, while greenhouse gas build-up causes temperatures close to Earth's surface to rise, it cause temperatures higher up, in the stratosphere, to fall.
stratosphere The region of the upper atmosphere extending from the tropopause (8 to 15 km altitude) to about 50 km. The thermal structure is determined by its radiation balance and is generally very stable with low humidity.
stratosphere The layer of air that extends from about 10 to 30 mile above the surface of the earth. sulfur dioxide A colorless gas that can that can bother the lungs. It is formed when fossil fuels that contain sulfur are burned.
