Group description

The research carried out in the Aerosol Physics Group focuses on atmospheric aerosols, which are liquid or solid particles suspended in air. The group studies how atmospheric aerosols form and transform in the atmosphere and the role they play in the Earth’s climate through their interactions with clouds.

The group has a unique capability of integrating laboratory and outdoor measurements with theories and models in order to understand and predict the impacts of human-caused and natural changes on climate. Aerosol physics group is in central role in UEF top level strategic research community Climate Forcing, Ecosystems and Health (CLEHE) and in Finnish Academy Flagship Atmosphere and Climate Competence Center (ACCC).
