History of the study of atmospheric ozone - NASA

From these measurements they deduced that the total amount of ozone in the atmosphere was equivalent to a layer at normal temperature and pressure which would be only 5 mm in thickness. Fowler and Strutt (who became Lord Rayleigh) showed in 1917 (6) that near the edge of the cutoff in the solar spectrum, a number of absorption bands could be observed.

Ozone layer - Wikipedia

This type of instrument was first used for ozone detection from aircraft and balloons, but with a few modifications it is now ready for use in the marine boundary layer. The instrument's design offers sensitive and accurate ozone measurements, while still being compact and durable. Its waterproof casing is 55 x 34 x 22 cm, and the entire package weighs about 19 kg. The instrument is able to operate …

: ozone meter

In the stratosphere the temperature of the atmosphere rises with increasing height, a phenomenon created by the absorption of solar radiation by the ozone layer. The ozone layer effectively blocks almost all solar radiation of wavelengths less than 290 nanometres from reaching Earth’s surface, including certain types of ultraviolet (UV) and other forms of radiation that could injure or kill most living things.

NASA Reports Arctic Ozone Hit Record Low in March | NASA

NASA Reports Arctic Stratospheric Ozone Depletion Hit Record Low in March. Ozone levels above the Arctic reached a record low for March, NASA researchers report. An analysis of satellite observations show that ozone levels reached their lowest point on March 12 at 205 Dobson units. While such low levels are rare, they are not unprecedented.

Ozone Layer - Our World in Data

Ozone concentrations are measured in Dobson Units (DU): this is number of molecules of ozone that would be required to create a layer of pure ozone millimeters thick at a temperature of 0 degrees Celsius and a pressure of 1 atmosphere. An ‘Ozone Hole’ would approximate to an area where the ozone concentration drops to an average of around 100 Dobson Units.

Ozone Layer - Our World in Data

The stratosphere includes the zone termed the ‘ozone layer’.Ozone in the stratosphere plays a very different role to that in the layer below. In the ozone layer, it is often referred to as ‘good’ ozone since it plays a crucial role in absorbing potentially dangerous ultraviolet (UV-B) radiation from the sun.

ozone layer | National Geographic Society

The ozone layer is one layer of the stratosphere, the second layer of the Earth’s atmosphere. The stratosphere is the mass of protective gases cling ing to our planet. The stratosphere gets its name because it is stratified, or layered: as elevation increases, the stratosphere gets warmer.

Is the ozone hole causing climate change? – Climate Change ...

· The ozone layer, which lies high in the atmosphere, shields us from harmful ultraviolet (UV) rays that come from the Sun. Human activities effectively punched a hole in it, through the use of gases like chlorofluorocarbons (CFCs) in spray cans and refrigerants, which break down ozone molecules in the upper atmosphere. While some extra UV rays slip through the ozone hole, their net effect is to ...
