Abstract:  This lecture is an introduction to tropospheric chemistry. You will learn about trace gases in the troposphere whose reactivity lead to a multifaceted (and multi-phase) chemistry, significantly more complicated than that of the stratosphere. We will focus on the major chemical reactions/cycles in the troposphere, make you familiar with the quantitative treatment of those, and introduce you to the different measurement techniques used for individual trace gases of importance. You will learn what we know about the creation of “summer smog”, and why ozone is such an important trace component. In addition the coupling between changes in the chemical
composition of the troposphere and climate will be addressed.
