We study the chemical and dynamical processes which affect the composition of the natural and polluted atmosphere from the surface to about 100 km. We develop and use detailed 3-D models and use observations from a wide range of platforms.

Ozone return dates from CCMI simulations

As part of the modelling work for the WMO/UNEP 2018 Ozone Assessment (in support of the Montreal Protocol) we have led a study of stratospheric ozone recovery. We analysed around 20 chemistry-climate models to estimate the dates by when ozone will return to 1980 levels. See Dhomse et al., (ACP, 2018).
