Trace gas transport in the stratosphere: Diagnostic tools and techniques
The study of stratospheric trace gases over the last 20 years has spurred the development of new methods and techniques for
analyzing observations that have resulted in a comprehensive understanding of stratospheric chemistry and dynamics and a significant
improvement in numerical methods. These analysis techniques and numerical methods are somewhat scattered throughout the literature
and are gathered together here and placed in context. To do this, we first provide a brief overview of stratospheric dynamics
and transport as seen through the distribution of trace gases. We then provide a summary of some of the more popular methods
used to analyze observations including trajectory models, potential vorticity-based analyses, and the age-of-air diagnostic.
We then describe the class of conservative numerical schemes now used to model trace gas distributions.
