\subsection{Instruments and Data}  Ozonesondes from Davis, Macquarie, and Broadmeadow(Melbourne) are released roughly weekly and capture ozone, temperature, pressure, relative humidity, and geopotential height up to around 700 times between the surface and 30km.  The information was gathered and provided by TODO: What were department names?  Data exists from around 2000 to 2013 TODO: more exact? make table?  The weekly releases occasionally capture one profile of an event, and we can only estimate the lifetime and shape of the ozone intrusion based on the ECMWF Reanalysis Interim(ERA-I) data.  In order to look at synoptic scale weather patterns during diagnosed STTs we are using the ERA-I datasets available from \cite{ECMWFDATA}.  The ERA-I data we used for synoptic weather was of one degree horizontal resolution with pressure levels at 200, 300, 400, and 500 hPa.  For individual cases ERA-I data was downloaded at .25 degree horizontal resolution with the full 34 pressure levels from 1000 to 1 hPa.
