On Aerosol-cloud Studies at the Puijo Semiurban Measurement Station

A measurement site for aerosol-cloud interaction studies is described. The newly established measurement site at Puijo observation tower produces data from semiurban environment for climatic models and particle formation studies. In addition to the basic measurements, intensive yearly measurement campaigns are organized at the station. The first aerosol-cloud interaction experiment (PUCE1) took place in October-November 2006. Some results of the measurement campaing are presented and discussed.
