 24 March 2008 Jery Stedinger Lecture 23-24 6 Learning Objectives Students should be familiar with key  air pollutants ,  their sources  and their effect on human health. They should know dimensions, differences between, and causes of  stratospheric ozone depletion, greenhouse gas warming, acid rain,  and tropospheric air pollution (including smog).  They should also be able to describe effect of atmospheric stability  and atmospheric temperature profiles on troposphere air pollution  dynamics.  They should be able to use Gaussian plume and deposition models  to estimate environmental concentrations of pollutants

Want student to appreciate how the transport rates through those pathways are modeled, including: a) Structure of models employed b) Sources of parameters and their character c) Major strengths and weakness of models d) Likely precision of parameters and of models e) How models fit into quantitative risk assessments
