Professor John Pyle research's involves the use of state-of-the-art numerical models, run on supercomputers, to study the processes controlling the present state of the atmosphere and its evolution. Collaborating closely with scientists at the Department of Applied Mathematics and Theoretical Physics, his group’s research interests include

Stratospheric Modelling
The chemistry, dynamics and radiative transfer of the stratosphere are being studied using a number of numerical models; in particular they are investigating the rapid depletion of ozone found recently in the polar spring.

Tropospheric Modelling
The group have developed a range of models for studying the chemistry of the lower atmosphere, from complex 3D models to models based on air parcel trajectories.

Chemistry/climate interactions
Professor Pyle and his team have developed a detailed chemistry package which has been included into the Met Office's climate model, to study composition change in surface ozone since the industrial revolution and into the future.

Atmospheric composition measurements
The group has developed lightweight gas chromatography instruments to measure halocarbons; which have been deployed from balloons and high-flying research aircraft.
