Unit 1
The main oxidants in the troposphere and how we observe them

The troposphere is the most chemically reactive part of the atmosphere.

Most chemical reactions which occur in the troposphere involve oxidation.  In this unit we look at the major oxidising species during the day and during the night and how we go about measuring them.

 

butane oxidation

1. We will discuss only basic atmospheric chemistry in this unit.  However the chemistry which goes on can be really complicated.  Just have a look at the atmospheric chemistry of a simple organic molecule such as butane (which is used, for example, in camping stoves).  Click the image for a better view!  From: lecture by Jim Smith at NCAR.
