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 …

Solar Activity Impacts Polar Ozone

14.10.2014 8:59 Increase in greenhouse gases explains, to a large extent, the rise in the average temperature of the Earth. According to the research study published in Nature Communications today, the Sun affects middle atmosphere ozone with potential implications on smaller scale to regional, but not global, climate. Mankind is responsible for the global warming …

Ozone Depleting Chemicals

CFCs The destruction of ozone is accelerated by certain trace gases containing nitrogen, hydrogen, bromine, and chlorine. These are referred to as ozone depletion chemicals. Consumption of ozone depleting substances expressed as million tonnes of ozone depletion potential (ODP), 1989-2009. ODP is a number that refers to the amount of ozone depletion caused by a …
