The research project is called INTEGRATE and will seek to transform the way we think about the molecular phase transitions leading to aerosol and cloud formation – treating the full continuum from gas phase molecules to the water droplets and ice crystals that clouds consist of.
“This molecular-level knowledge will be used to improve 3-dimensional models simulating the evolution of clouds and the atmospheric processes in their vicinity. Finally, the impacts of clouds and precipitation on future aerosol loadings and the related feedbacks will be investigated to yield more reliable projections on air quality, climate, and their interactions”, says Ilona Riipinen.
Despite their abundance in the Earth’s atmosphere, cloud formation and evolution are still poorly understood. This is particularly true for the interactions clouds have with atmospheric aerosol particles and their precursor vapors, which hampers our knowledge on the role that clouds and precipitation play in the climate system and in governing air quality.
INTEGRATE will address these inconsistencies, and acquire a comprehensive picture of the phase transitions leading to cloud formation over the relevant scales.
“If successful, INTEGRATE will open new avenues for fundamental understanding of the physics and chemistry of atmospheric phase transitions, improved climate projections and ultimately better policies for reaching the targets of the Paris agreement”, says Ilona Riipinen.
The ERC Consolidator Grant is for 5 years and close to 3 million euro.
