Ozone Hole History

The ozone first started getting measured from the ground in the 1950’s. This happened in Halley Bay, Antarctica. As technology grew satellite measurements started in the 1970’s. The Nimbus-7 satellite managed to get the first worldwide measurement of the Ozone layer. In 1928 chloroflourocarbons were created. These are non-toxic and non-flammable refrigerants. Chloroflourocarbon became available …

Ozone Hole Consequences

What is the ozone layer? The sun emits ultraviolet sun rays to the earth’s surface. The impact of the rays’ wavelength and intensity depends on the distance the rays cover to the earth’s surface and the availability of obstacles to stop the rays from directly hitting the earth’s surface. The only obstacle stopping the rays …

The Ozone Layer Fact Sheet

Ozone Background Ozone is a chemical compound containing three oxygen atoms, that is one more than the gas we breathe. Though ever prevalent and important to earth’s atmosphere, it was not discovered until 1839 by Christian Friedrich Schonbein. Ozone can actually be harmful to humans when present in high concentrations in the troposphere, the part …

Polar Stratospheric Clouds

Paying attention to nacreous clouds in the stratosphere these are wave clouds found on the windward side of the mountain ranges that generate forces of gravity. These clouds have sheet-like arrangements that gradually rise and fall while extending amid the emerging waves. Besides, nacreous clouds are usually linked with extra-high surface breezes that show the …

The Montreal Protocol on Substances that Deplete the Ozone Layer

The Antarctic ozone hole was first discovered in 1985. As a result, a mechanism for international cooperation was established by the Vienna Convention and tasked with responsibilities of researching ozone layer and ozone-depleting chemicals and their effects. It is at the Vienna Convention where the Montreal Protocol on substances that deplete ozone layer was discussed …
