NASA - Ozone: What is it, and why do we care about it?


Ozone hole. Ozone depletion is greatest at the South Pole. It occurs mainly in late winter and early spring (August-November) and peak depletion usually occurs in early October, when ozone is often completely destroyed in large areas. This severe depletion creates the so-called “ozone hole” that can be seen in images of Antarctic ozone, made using satellite observations. In most years, the.

Holes in the Ozone Layer Ozone, 03 is a highly important component of the earth's atmosphere. Close to the ground ozone, is produced by the action of light on exhaust fumes and so concentrates in areas of heavy traffic. In this was it can be a pollutant, it corrodes metal, can inhibit plant growth and cause irritation to the lungs and throat. Up in the stratosphere though, about 15-50km above.

Conclusions: Looking back over the scientific investigation of ozone depletion, we can see how the Molina-Rowland hypothesis evolved with new data. When chlorine nitrate, a chemical that ties up chlorine in an ozone-safe form, was added to the hypothesis, the expected amount of ozone loss decreased. Then, when polar clouds were considered, the expected ozone loss increased. Through all these.

These clouds are responsible for chemical changes that promote.
