A grand challenge in the field of chemistry-climate modelling is understanding the connection between anthropogenic emissions, atmospheric composition and the radiative forcing of trace gases and aerosols.
My talk focuses on what a whole-atmosphere chemistry-climate model can tell us about methane and ozone. Methane is an important greenhouse gas but its treatment in chemistry-climate models can be improved by moving from the commonly used latitude-invariant ‘lower boundary condition’, which prescribes the methane concentration at the surface, to a flux-based emissions treatment. I’ll describe the impact of such an improvement on the performance of UKCA, a key component of the UK Earth System Model, UKESM-1.
Tropospheric ozone is a pollutant levels of which impact human health, agricultural productivity and radiative forcing. The second part of my talk will describe how a whole atmosphere chemistry-climate model allows us to attribute the drivers of the ozone budget. I’ll describe recent work examining how stratospheric ozone depletion has influenced tropospheric ozone and draw on a recent CMIP6 analysis of how tropospheric ozone will evolve over the 21st century.

CMIP6 offers the opportunity for the first time to connect changes in emissions to climate forcing via the underpinning chemical processes using Earth system models. Of particular interest are the radiatively active gases tropospheric ozone and methane, which form part of a coupled chemical system, mediated by interactions between NOx, OH, CO and other VOCs.

A grand challenge in the field of chemistry-climate modelling is to understand the connection between anthropogenic emissions, atmospheric composition and the radiative forcing of trace gases and aerosols. The AerChemMIP model intercomparison project, part of CMIP6 and due to begin in 2018, focuses on calculating the radiative forcing of gases and aerosol particles over the period 1850 to 2100.
