Formation and growth of fresh atmospheric aerosols: eight years of aerosol size distribution data from SMEAR II, Hyytiälä, Finland

We analyzed size distributions measured continuously at a boreal forest measurement site at Hyytiälä, Finland between 1996 and 2003. The mean growth rate was 3.0 nm h–1, peaking in summer.

• 1 From the eight-year data we identified days when new aerosol particle formation was taking place as well as days when no formation was detected, removing days with ambiguous status.
• 2 The event days were then classified based on whether it was possible to determine formation and growth rates of new particles.
• 3 These characteristics were then calculated.

This work deepens our understanding of the fundamental laws governing the universe, from subatomic particles to cosmic structures.
