Research Paper Ozone Depletion - s3.amazonaws.com.
The Antarctic ozone hole, as it came to be known, made depletion of the ozone layer a real and present danger to lawmakers and the public at large. Predictions of significant increases in the incidence of skin cancer resulting from continued use of CFCs spurred international action. In 1987, 56 countries agreed under what became known as the Montreal Protocol to cut CFC production and use in.
Ozone depletion describes two distinct but related phenomena observed since the late 1970s: (1) a steady decline in the total amount of ozone in earth’s stratosphere (i.e., the ozone layer), and (2) a much larger springtime decrease in stratospheric ozone around earth’s polar regions. The latter phenomenon is referred to as the ozone hole. The details of ozone-hole formation in the polar.
The Centre for Atmospheric Science is a joint venture within the University of Cambridge between the University Departments of Chemistry, Applied Mathematics and Theoretical Physics and Geography. The Centre is one of the premier research groups in the UK for atmospheric research and attracts funding from a wide range of sources. Post-doctoral researchers and students from the UK and abroad.
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.

Ozone depletion describes the observed loss of ozone in the stratosphere over the past 50 years. It encompasses both a steady thinning of the ozone layer at mid-latitudes and its catastrophic.
History of the study of atmospheric ozone. Richard S. Stolarski. NASA Goddard Space Flight Center. Greenbelt, MD 20771. USA. Abstract. Ozone is a substance that touches on our modern society in many ways. Ozone is used in industrial processes and as a disinfectant. Ozone is a strong oxidizing agent that is present in photochemical smog. Ozone in the stratosphere screens the surface of the.
