Session Upper Tropospheric and Stratospheric Processes (chemical, radiative and dynamical)


Description:

This session invites studies addressing upper tropospheric and stratospheric composition and interactions with chemistry, dynamics and climate. Of particular interest are studies examining stratospheric ozone changes associated with controls imposed by the Montreal Protocol, those examining upper troposphere/lower stratosphere composition using measurements from recent field campaigns, and studies on chemical and dynamical perturbations on the upper troposphere and stratosphere due to episodic events such as large pyro-cumulonimbus events and volcanic eruptions that reach the stratosphere as well as perturbations caused by the space launch industry.  Reports on recent stratospheric aircraft campaigns addressing upper troposphere and stratosphere processes are welcome. Additional topics that would be applicable for this session are: 1) trends and variability in stratospheric composition; 2) the effects of increasing greenhouse gases on ozone recovery; 3) the relation between stratospheric composition and surface climate; 4) stratospheric aerosol-ozone-climate interactions associated with geo-engineering schemes. Observational and modeling studies ranging from local to global spatial scales and seasonal to centennial time scales are welcome.
