Formation mechanism of aerosol particles still a big uncertainty in predicting climate change

Formation mechanism of aerosol particles still a big uncertainty in predicting climate change

A recent doctoral dissertation at the Finnish Meteorological Institute studied the formation of particles through the so called gas-to-liquid phase transition i.e. nucleation. The nucleation mechanism is one of the biggest uncertainties in climate models. The results of the dissertation help understand this mechanism and the role of compounds affecting it. The study also shows that the diversity of compounds affecting formation of aerosol particles is greater than it has been assumed.
