Themed Joint Session 4 Stratospheric Ozone, Chemistry, and Climate—Part I

Tuesday, 8 January 2019: 8:30 AM-10:00 AM
West 212A (Phoenix Convention Center - West and North Buildings)
Hosts: (Joint between the 20th Conference on Middle Atmosphere; the 32nd Conference on Climate Variability and Change; and the 21st Conference on Atmospheric Chemistry )
Karen H. Rosenlof, NOAA/ESRL, Chemical Sciences Division, Boulder, CO and Paul A. Newman, NASA GSFC, Earth Sciences Directorate, Greenbelt, MD
John S. Daniel, NOAA, ESRL Chemical Sciences Division, Boulder, CO and Amy Butler, CIRES, Boulder, CO

This session welcomes submissions addressing the past and projected evolution of stratospheric ozone and its interplay with climate. Topics covered include estimates of trends and variability in stratospheric ozone, the effects of increasing greenhouse gases on ozone recovery, the climate effects of HFCs, how changes in stratospheric ozone translate to changes in atmospheric circulation and surface climate,  stratospheric aerosol–ozone–climate interactions associated with volcanic eruptions or geoengineering schemes, and changes associated with controls imposed by the Montreal Protocol and its subsequent amendments. Modeling and observational studies on local to global spatial scales and seasonal to centennial time scales are welcome.
