Having already comprehensively modelled London, King’s are focusing on developing modelling methods to predict particle (PM2.5) air pollution in Accra (Ghana) and to apply these to Dhaka. The modelling approach will use a combination of chemical transport models (WRF-Chem), satellite imagery and ground based measurements and will benefit from 10 fixed air pollution monitoring sites and a hundred temporary monitoring sites around the city.
There are many challenges to undertaking air pollution modelling in cities such as Accra including; obtaining geographically detailed emissions information such as road traffic, wood burning from cooking and industrial emissions. To address this, investigation will be made of the value of using satellite imagery to ‘spot’ pollution sources alongside other data such as videos.
Applying the correct emissions factors for sources such as cooking and transport is also problematic and will be addressed with measurement campaigns of specific sources.
Finally, correctly predicting larger scale influences on air pollution such as the occurrence of regular land-sea breezes, as well as the influence of the Sahara, will also be critical.
