Professor John Pyle

Professor John Pyle's research 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. Particular problems being tackled include the rapid depletion of ozone found recently in the polar spring, the so-called 'ozone hole', the changing oxidizing capacity of the troposphere (the ability of the troposphere to cleanse itself of pollution) and the development of lightweight gas chromatography instruments to measure halocarbons, as deployed from balloons and high-flying research aircraft.
