Concentrations and fluxes of aerosol particles during the LAPBIAT measurement campaign in Värriö field station
International audience The LAPBIAT measurement campaign took place in the SMEAR I measurement station located in Eastern Lapland in the spring of 2003 between 26 April and 11 May. In this paper we describe the measurement campaign, concentrations and fluxes of aerosol particles, air ions and trace g...
