Present research/ Professional Speciality

  • Application of ground-based millimetre-wave measurements of ClO
  • Chemical ozone loss processes in the polar stratosphere. Study of the ClO dimer kinetics using ground-based measurements combined with an optimal estimation approach.
  • Development and improvement of semi-empirical models describing chlorine activation, deactivation and related ozone depletion in the polar stratosphere
  • Application of semi-empirical models to project the future evolution of ozone in the Antarctic stratosphere.

  • Analyze EPIC output to quantify changes in future extreme weather events for New Zealand for a wide range of possible future GHG emissions scenarios and for a range of climate models (Climate Changes Impacts and Implications). 
Field work
  • 2008/2009/2011 visit to Scott Base, Antarctica to maintain/calibrate the ClO microwave radiometer (Chloe) which is jointly operated by NIWA and NRL
