Abstract

Tracer observations from balloon-borne in-situ measurements and satellite observations have been transferred into mean age of stratospheric air. A 30-year time series of mean age of air from balloon observations for the period 1975 to 2005 has been generated. This time series indicated a trend of the stratospheric mean age for Northern midlatitudes which was positive or consistent to zero within its error bars, in apparent contradiction to results from Chemistry-Climate models. Satellite observations from the MIPAS instrument onboard of Envisat provided, for the first time ever, a global view of the stratospheric mean age, covering the period from 2002 to 2010, and the altitude range from 10 to 40 km. Analysis of MIPAS observations confirmed the positive trend of age of air for Northern midlatitudes, and provided a vertically resolved picture.
