MODELING EARTH’S ATMOSPHERIC

Draw the ozone layer. This is not a main layer of the atmosphere, but plays an important role in how it works. This is also where the ozone is found, which absorbs ultraviolet radiation. The ozone is between the stratosphere and the mesosphere. Its symbol is 0 3 because it is made of three oxygen atoms.

b. Standard distribution of atmospheric absorbers. In this subsection, the vertical distributions of water vapor, carbon dioxide, ozone, and cloud, which are used for the computations of thermal equilibrium, and those of heat balance in the following section, are described. They are adopted unless we specify otherwise.

Atmospheric Ozone Chemistry - Columbia University

The Kinetics of Atmospheric Ozone Ozone is a minor component of the earth’s atmosphere (0.02 – 0.1 parts per million based on volume (ppmv)), yet it has a significant role in sustaining life on earth. It absorbs ultraviolet (uv) radiation from the sun and hence reduces the levels of uv radiation reaching the earth’s surface .

Atmospheric Chemistry and Greenhouse Gases

The atmospheric burden of nitrous oxide (N 2O) continues to increase by about 0.25%/yr. New, higher estimates of emissions from agricultural sources improve our understanding of the global N 2O budget. The atmospheric abundances of major greenhouse gases that deplete stratospheric ozone are decreasing (CFC-11, CFC-113, CH 3CCl 3, CCl

ozone: The oxygen atom reacts quickly with water to form 2 molecules of hydroxyl in a bimolecular reaction (reaction involving two reactants): The net result of this sequence is the formation of OH from ozone photolysis: Reactions 1 and 2 are elementary reactions, that is, they cannot be subdivided into two or more simpler reactions.
