Analysis of the growth of nucleation mode particles observed in Boreal forest

Aerosol formation and subsequent particle growth in the ambient air have been frequently observed at a boreal forest site, Southern Finland. During a 1-year period we have observed significant aerosol formation on more than 50 days. Submicron aerosol size distributions have been measured using differential mobility analyzing technique. On several days, the growth of nucleation mode particles to Aitken mode has been observed to take place within...
