Atmospheric modelling

The modelling group's emphasis is on climate and aerosols. The group members use models like ECHAM, WRF, and GLOMAP to investigate the effects of aerosols on the climate.

Current research topics include:

  • stratospheric sulphur emissions from large volcanic eruptions
  • solar radiation management geo-engineering
  • ternary amine nucleation in the boundary layer
  • better representation of clouds at both LES and GCM resolutions
  • improved estimates of the proportion of brown carbon found in aerosol emissions

Does Increasing Temperature Increase Carbonaceous Aerosol's direct radiative effect over boreal forests?

The main objective of this project is to determine the cause of the increased negative aerosol direct radiative effect over boreal forests when the temperature increases. The research will integrate data from the remote-sensing AATSR instrument and the ECHAM-HAMMOZ climate model, which will be used to estimate the significance of the boreal carbonaceous cooling in the larger context of climate change.

Research highlight: ECLAIRE (Emulating the CLoud-Aerosol Indirect Radiative Effect)

The aim of this project is to improve the representation of sub-grid variation in clouds by creating an emulator of an LES-scale model. The emulator can then be used to provide an improved estimate of the aerosol indirect effect - currently the largest uncertainty in the IPCC's estimates of climate forcing.
