The stratosphere is a complex region of the atmosphere in which dynamics chemistry and radiation interact with often similar timescales. Because of the strong coupling, concepts such as cause and effect have less meaning than in a more linear system. Scientific issues of interest include the simulation and behaviour of the Antarctic ozone hole, the timing of ozone recovery and the impact of changing greenhouse gas concentrations on stratospheric processes. The interactions between chemistry and climate and between the stratosphere and troposphere are investigated using multi-decadal simulations of AMTRAC (Atmospheric Model with TRansport And Chemistry) --- the GFDL climate model with a chemical module added. The chemical module is an improved version of that used in the UK Met. Office model UMETRAC (Unified Model with Eulerian TRansport And Chemistry), developed by yours truly and coworkers (see publication list).

JA is also editor for JGR - Atmospheres from Jan 2005 to Dec 2008.

Collaborations

The main collaborations are focused around coupled chemistry climate model validation and collaborations in conjunction with the WMO ozone reports, involving many institutions worldwide. In addition a separate collaboration has been continuing with GFDL, UKMO and NIWA, New Zealand, with the latter institution running the same photochemical model as AMTRAC but in the Met. Office Unified Model.

Current Work

Work is geared towards the 2010 WMO Ozone assessment.
