(SFC) Mobile surface station at Åre, SWEDEN
|Category:||Tundra, located near the top of the Swedish peak "Åreskutan"|
|Site Access:||aerial tramway from the valley below|
|Time offsets:||Current local time (CEST) = +2 GMT
Current local time (CEST) = +8 MDT
|Collaborating Institutes:||Department of Meteorology, Stockholm University|
|Status:||Short-term field campaign, July 2003|
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?

The view spans an elevation range from 400 m (lake) to 1440 m (peak of Åreskutan). The sampling station is ca. 100 m west of the upper terminus of the aerial tramway, indicated by the arrow.
