Title: Using tracer data to examine large-scale mixing in the stratosphere

The stratospheric circulation determines the distribution of radiatively important trace gases, such as ozone and water vapor. In this talk, I will review recent advances in the application of stratospheric tracer data to understand the circulation. I will discuss the history and current state of observations of long lived trace gases in the stratosphere and show some new methods that hold the promise of enabling a much more comprehensive analysis of the circulation and its trends. I will also present results quantifying the circulation and mixing from satellite data; uncertainties using this method are large and will be discussed, but the results are extremely promising.
