Chemical composition and size distribution of fine aerosol particles measured with AMS on the East Coast of the Baltic Sea
The size distribution and chemical composition of ambient aerosols were analyzed using an Aerodyne aerosol mass spectrometer (AMS) at Preila station during 3-15 September 2006. The major observed components of the aerosol were sulfates and organics with a smaller amount of nitrates and ammonium. Lar...
