Stratospheric composition change, its impact on climate and understanding of uncertainties in data records.
Stratospheric composition change, its impact on climate and understanding of uncertainties in data records.
Session ID#: 80537
Session Description:
Stratospheric ozone, water vapor, and temperature changes were shown to have far-reaching impacts on climate through radiative and dynamical effects. Modeling and observational studies have detected the imprint of stratospheric composition changes on the subtropical and midlatitude atmospheric circulation with associated impacts on the ocean circulation, sea ice, and regional surface climate. Uncertainties remain in the observed stratospheric changes. The understanding of the climate response to ozone changes in the future is complicated by the interplay between ozone recovery and greenhouse gases. We invite papers on all aspects of long-term atmospheric composition changes in the stratosphere and upper troposphere, and associated climate impacts in both hemispheres and on all timescales. Of particular interest are data produced through merging multiple data records to improve spatial or temporal sampling or to extend the record in time. Attribution of observed and modeled long-term changes in atmospheric composition will be discussed in this session.
