Ultraviolet radiation Electromagnetic radiation of shorter wavelength than visible radiation but longer than x-rays; roughly, radiation in the wavelength interval from 10 to 4000 angstroms.
Ultraviolet Radiation The energy range just beyond the violet end of the visible spectrum.
Ultraviolet Radiation: Ultraviolet radiation (UV) is one form of radiant energy coming from the sun. The sun emits a range of energy known as the electromagnetic spectrum.

Australians experience the highest rates of skin cancer in the world. A tan may look healthy, but if it's not your natural skin colour then you've got poor sun protection.

Ultraviolet Radiation: Electromagnetic radiation with wavelengths between approximately .2 to .4 microns.
Updraft: A current of air that has a marked upward vertical motion. Updrafts keep cloud particles suspended in the air.
Ultraviolet radiation Electromagnetic radiation with a wavelength between 0.1 and 0.4 micrometers.
Wall cloud An area of rotating clouds that extends beneath a severe thunderstorm and from which a funnel cloud may appear.
Ultraviolet radiation Electromagnetic radiation with wave-lengths longer than X-rays but shorter than visible light.
Upslope fog Fog formed as moist, stable air flows upward over a topographic barrier.
Ultraviolet radiation Short-wave, energetic electromagnetic radiation emitted by the sun. Much of the solar ultraviolet radiation is absorbed in the stratosphere, where it is involved in the formation and destruction of ozone.
It is a very strong absorber of ultraviolet radiation, and the presence of the ozone layer in the upper atmosphere provides an ozone shield that prevents dangerous radiation from reaching the earth's surface and allows the existence of life in its ...
A powerful oxidizing agent that is considered a pollutant in the lower troposphere but an essential chemical in the stratosphere where it protects the earth from high-energy ultraviolet radiation from the sun.
The stratosphere is layered in temperature because it is heated from above by absorption of ultraviolet radiation from the Sun.
Ultraviolet (UV) (or Ultraviolet Radiation) - Ultraviolet radiation from the sun plays a role in the formation of the ozone layer by acting as a catalyst for a chemical reaction that breaks apart oxygen molecules which then recombine to form ...
The layer of ozone that begins approximately 15 km above Earth and thins to an almost negligible amount at about 50 km, shields the Earth from harmful ultraviolet radiation from the sun.
Upper Level Low: An area of cold air aloft rotating counter-clockwise.
UV Rays: (UV) Ultraviolet Radiation: Shortwave electromagnetic radition emitted by the Sun.
UV Rays: (UV) Ultraviolet Radiation: Bad between 10am and 2pm for sunbathing.
It acts as a filtering mechanism against incoming ultraviolet radiation. It is located between the troposphere and the stratosphere, around 9.5 to 12.5 miles (15 to 20 kilometers) above the earth's surface.
Very energetic electromagnetic radiation with wavelengths intermediate between 0.01 and 10 nanometers (0.1-100 Angstroms) or between gamma rays and ultraviolet radiation. Essentially all X-Rays from space are absorbed in the Earth's upper atmosphere.
ozone: gaseous form of oxygen that constitutes less than one part per million of the gases in the atmosphere, yet absorbs most of the ultraviolet radiation which has been proven to be harmful to humans as well as other life forms on Earth.
OZONE: A form of oxygen containing 3 molecules, usually found in the stratosphere, and responsible for filtering out much of the sun's ultraviolet radiation.
PACIFIC HIGH: A semipermanent anticyclone located in the Eastern North Pacific.
Its production results from photochemical process involving ultraviolet radiation. Because it absorbs harmful radiation at those heights, it is a very beneficial gas.
Ozone shield Stratospheric ozone layer, giving protection to the Earth's surface due to intense absorption of harmful solar ultraviolet radiation by the gas.
Ozone Shield
Protection given to the Earth's surface by the stratospheric ozone layer due to intense absorption of solar ultraviolet radiation by the gas.
CFCs- short for "chlorofluorocarbons," a family of industrial gases. CFCs interfere with the natural cycle of ozone formation in the upper atmosphere, which acts as a barrier to harmful ultraviolet radiation.
Ozone - A form of oxygen in which the molecule is made of 3 atoms instead of the usual two. Ozone is usually found in the stratosphere, and responsible for filtering out much of the sun's ultraviolet radiation. It is also a primary component of smog.
Ozone - A form of oxygen that has a weak chlorine odor. Ozone heats the upper atmosphere by absorbing ultraviolet from sunlight. In the troposphere, ozone is a pollutant, but in the stratosphere it filters out harmful ultraviolet radiation.
is located in a natural layer far above the surface of the globe, in a frigid region of the atmosphere known as the stratosphere. Here in this outer region it protects the earth and its inhabitants from the harmful effects of ultraviolet radiation ...
In the statosphere, it occurs naturally and it provides a protective layer shielding the Earth from ultraviolet radiation and subsequent harmful health effects on humans and the environment.
Ozone is usually found in the stratosphere, and responsible for filtering out much of the sun's ultraviolet radiation. It is also a primary component of smog.Ozone holeA thinning of the ozone layer over Antarctica, which occurs each spring.
