Project Summary

A month-long field campaign was conducted on the Swedish peak Åreskutan in July, 2003 to study the interactions between aerosol particles and clouds. Researchers from the University of Stockholm (Sweden), Max-Planck Institute for Chemistry (Mainz, Germany), University of Washington (Seattle, WA), Princeton University (Princeton, NJ) and NOAA (Boulder, CO) measured the chemical composition, size distribution, and radiative properties of aerosol particles within cloud droplets, in the interstitial air between cloud droplets, and in cloud-free air at a field laboratory near the top of the mountain. The primary questions that were addressed during the project are:

  • how does the chemical composition of the particle influence which ones are scavenged by clouds?
  • how are the radiative properties of aerosol particles changed by clouds?
  • what are the sources for individual particles on which cloud droplets form?
  • how do anthropogenically produced particles influence cloud properties?
