Reading to be done before Class: Re-Read CES pp. 106-113
Come to class with a basic familiarity with the following concepts and ideas: We won't have much time in lecture to cover the structure of the atmosphere so be sure to take good notes from your book. To aid in your reading and studying you might want to create a chart that lists each major pollutant below, its characteristics, its sources, and its effects. The following are concepts you should be familiar with: Troposphere, aerosols, stratosphere, ozone, mesosphere, thermosphere, importance of oxygen, negative and positive lapse rates, thermal inversion, particulate matter, incomplete combustion. Sources and effects of the following air pollutants: particulate matter, sulfur dioxide, carbon monoxide, atmospheric hydrocarbons, nitrogen oxide, ozone, photochemical smog, carbon dioxide, methane.
