9 th ORM Geneva 14 May 2014 SAP Cochairs Ayit é Lô Ajavon Togo Paul Newman USA John Pyle UK AR Ravishankara USA Chapter 4 of the upcoming assessment deals with Stratospheric ozone changes and climate. DEPLETION. What is Ozone?. Two different layers in the atmosphere:. . Troposphere. Stratosphere. . What is ozone layer?. Ozone layer is a thin, fragile shield that contains relatively high concentrations of ozone.. The . ozone layer. is a layer in . Earth's atmosphere. which contains relatively high concentrations of . ozone. (O. 3. ). . This layer absorbs 97–99% of the . Sun. 's high frequency . ultraviolet light. the progression of the Ozone hole over the antarctic from 1970 to 1997.. Some effects on plant and animal tissue as UV radiation increases. decrease in agricultural yields and a decrease in overall forest productivity.

Can OMPS . reasonably . represent the Antarctic ozone hole?. what is the nature of the atmosphere. We live at the bottom of a thin layer of gases surrounding the earth called the atmosphere, which is divided into smaller spherical layers. In the troposphere, the layer closest to earth, about 75-80% of the earths air mass is found here.. Ozone produced from the interaction of hydrocarbons and oxides in the presence of sunlight. At ground level, ozone is a pollutant; in the upper atmosphere it protects earth from excess radiation from sun. Ja. -Ho Koo. EAS 6792 Term project. Introduction. Tropospheric. ozone depletion event (ODE) usually happens in spring,. . polar. . region.. ODE looks strongly related to the amount of atmospheric bromine chemistry based on the heterogeneous reaction (Barrie et al., 1988).

TEMPO Science Team Meeting, Harvard-Smithsonian Center for Astrophysics. He estimated that Nitrogen oxides derived depletion of 10-90%. . Nobody at that time knew what the stratospheres natural concentration of Nitrogen oxide was, but even if you didn't know how much Nitrogen oxide there was, it's difficult to calculate its effect.. matter.

Ozone Profile and Tropospheric Ozone Algorithm: current implementation (OMI) and its adaption to TEMPO. Climate change is an extremely important and relevant topic. Climate change science needs to be better understood by society to enable the best decisions for responsible action. The PowerPoint slides in this file contain information about the science of climate change. Three other collections provide information about the effects of climate change and the effects of climate change on health. For the slides on causes and effects, please visit: . N. 2. O . under the.
