Aerosols and climate
The Aerosols and Climate research group studies small particles in the atmosphere, so called aerosol particles, including e.g. black carbon, dust, organics and bioaerosols. The group investigates the aerosol effects on Earth's climate and weather and the associated interactions. The research methods are primarily experimental, and the research is conducted in close collaboration with atmospheric modelers.
The group's research is divided into the following topics:
Interactions between aerosols and clouds
Particles from biomass burning
Cryospheric effects of aerosol particles
Bioaerosols
Observations to constrain global models
Additionally, the group is actively involved in developing the Aerosols, Clouds and Trace gases Research Infrastructure (ACTRIS). In this context, the group maintains and develops Cloudnet data portal for ground-based cloud remote sensing measurements. The group is also responsible for the development of the UAV measurement system and Doppler lidar remote sensing measurements. Furthermore, the group maintains continuous, comprehensive station measurements:
In Lapland at the Pallas measurement station: ground-based in situ and remote sensing measurements of aerosol particles and clouds
In the archipelago at the Utö measurement station: ground-based in situ measurements of aerosol particles
In Antarctica at the Marambio measurement station in collaboration with the Argentine Meteorological Service: ground-based in situ measurements of aerosol particles
