Aerosol particle formation events and analysis of high growth rates observed above a subarctic wetland-forest mosaic
An analysis of particle formation (PF) events over a subarctic mire in northern Swedenwas performed, based on number– size distributions of atmospheric aerosol particles (10–500 nm in diameter) and ions (0.4–40 nm in Tammet diameter). We present classification statistics for PF events from measureme...
