This final chapter continues the subjects of transport and modeling of radioactive aerosols by expanding discussion to the outdoor environment. We start with a discussion of wet (involving rain and snow) and dry (not involving rain and snow) deposition of aerosol particles to the earth’s surface. These are major removal processes for outdoor aerosol particles that, explicitly or implicitly, must be incorporated into most outdoor transport models. We next introduce the use of radioactive aerosols for tracer and timing studies. This is an important application involving radioactive aerosols that has proven to be useful for understanding a number of physical processes in the outdoor atmosphere such as atmospheric circulation patterns and aerosol-particle removal rates. Although tracer techniques are used to study complex processes in the atmosphere, many of the basic methods and examples can be understood as a “stand-alone” subject without prior exposure to atmospheric transport models.
