Project Summary

The QuIESCENT Arctic programme identifies the key challenges associated with understanding the role of aerosol-cloud interactions in the changing Arctic climate, providing a cross-disciplinary bridge between aerosols and clouds, physicists and chemists, and observations and models. We provide an international forum for national campaigns to share new knowledge, discuss new findings, and build new collaborations on the Arctic indirect effect.

Our goal is to assess and discuss key questions such as:

  • What are the sources of Arctic cloud condensation nuclei and ice nucleating particles, how do they affect clouds and climate, and will they change in future?
  • What is the role of anthropogenic (transported and local) pollution versus natural aerosol sources in influencing the microphysics of Arctic low level clouds?
  • What is the role of aerosol-cloud-radiation interactions in determining boundary layer mixing and processing/fate of local pollution in the Arctic boundary layer?
  • What is the role of the boundary layer structure and associated dynamics in the formation/processing of Arctic clouds (e.g., phase partitioning, cloud microphysics) and their interaction with aerosol particles?
