M. Kulmala et al., SIMULATIONS ON THE EFFECT OF SULFURIC-ACID FORMATION ON ATMOSPHERIC AEROSOL CONCENTRATIONS, Atmospheric environment, 29(3), 1995, pp. 377-382
The formation of new sulphuric acid-water droplets in atmospheric cond
itions is investigated. In the present study a two mode (new and pre-e
xisting) integral aerosol dynamics model is used. The model includes s
ulphuric acid formation in the homogeneous gas phase, nucleation, cond
ensation and coagulation. The simulations show the atmospheric conditi
ons, in which the formation of new particles is important, and enable
us to derive a simple analytical expression for these conditions.
