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 …
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 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 …
The ozone is a major component of the atmosphere that helps protect the Earth and keep the Earth within relatively stable conditions. As stratospheric ozone depletion occurs, it poses several serious risk factors for Earth and society. While ozone depletion is still being studied every day by leading experts worldwide, many things have already been …
Susan Solomon credit:NOAA September 15, 2006 NOAA Magazine — Twenty years ago this August, NOAA senior scientist Susan Solomon, along with other government and university scientists, identified the cause of the Antarctic ozone hole — a discovery that is still being celebrated as the most significant scientific/global environmental success story of the 20th century. Within …
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 …
The Ozone: What you need to know about the planetary blanket sheet that protects everyone from UV rays From a microscopic speck living at the bottom of the ocean to the foundation of a planet’s shield from ultraviolet rays? The process looked pretty nifty, as it started over a billion years ago, and that shield …

University of Colorado March 31, 2009 The global market for rocket launches may require more stringent regulation in order to prevent significant damage to Earth’s stratospheric ozone layer in the decades to come, according to a new study …
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 …
Recordstratospheric ozone loss in the arctic in spring of 2011Geneva, 5 April2011 GENEVA 5 APRIL 2011 (WMO) — Depletion of the ozone layer- the shield thatprotects life on Earth from harmful levels of ultraviolet rays – has reached anunprecedented level over the Arctic this spring because of the continuingpresence of ozone-depleting substances in the atmosphere …
