The EU-funded BACCHUS project aims to combine advanced measurements of cloud and aerosol properties with state-of-the-art numerical modelling in order to quantify key processes and feedbacks controlling aerosol-cloud interactions (ACI).
A team involving 20 research institutes around Europe is investigating the importance of biogenic versus anthropogenic emissions for ACI in regions that are key regulators of Earth's climate (e.g. the Amazon Rainforest) or are regarded as tipping points in the climate system (e.g. the Arctic).
The BACCHUS project is generating a unique database linking long-term observations and field campaign data of aerosol, cloud condensation and ice nuclei and cloud microphysical properties to enable a better quantification of natural aerosol concentrations and anthropogenic aerosol effects. As part of this project, in Leeds, we are using GLOMAP to model the global distribution of ice-nucleating particles.
