Description

Both stratospheric and tropospheric ozone have changed in concentration over the past few decades and further changes can be expected in the coming decades both as byproducts of human activity and as a result of efforts to limit factors which can affect ozone concentrations. The stratospheric community has been part of an international effort to develop methods of analyzing ozone data for change that have proven useful within and beyond the stratospheric community. The tropospheric ozone community is currently addressing a set of issues which also needs appropriate techniques to look for change including detecting, quantifying and understanding sudden changes, changes in trends, seasonal changes, diurnal changes and changes in extremes. A new international effort is beginning to work on these statistical and analytical challenges. Collaboration between the stratospheric and tropospheric communities is sought to assure the best approaches continue to serve science and society. Input from the LOTUS community is important to assure appropriate application of techniques in both the stratospheric and tropospheric communities. This presentation will include a review of the most common techniques currently in use and a brief summary of planned activities for the tropospheric community.
