Title: Ozonesonde climatology between 1995 and 2011 Description: An ozonesonde climatology based on ozone soundings for the last 17 years has been constructed for the community for model evaluation and comparisons to other observations. Ozone profiles for 42 stations around the globe have been compiled, averaged for the years 1980-1994 and 1995-2011. In addition to single stations, we provide regional aggregates combining stations with similar ozone characteristics. Please see the Technical Note below for using this data: Tilmes, S., J.-F.
