ERC project on Aerosol Effects on Convection

We have been awarded a five-year grant by the European Research Council to investigate Aerosol effects on convective clouds and climate (ACCLAIM).

In this project we will investigate highly uncertain aerosol-effects on convective clouds as potentially evident in the observed statistical correlation of satellite retrieved cloud top pressure and aerosol optical depth:

In ACCLAIM we will consistently combine global models, cloud resolving models and remote sensing data to advance our understanding on the physical processes underlying such observed relationships:
