| Abstract | ||
| More than three years of measurements of aerosol size-distribution and different gas and meteorological parameters made in a specific region were analyzed for this study to examine which of the meteorological and trace gas variables effect on the emergence of nucleation events. As an analysis method, we used discriminate analysis with non-parametric density estimation method. The best classification results in our data was reached with the combination of relative humidity ozone concentration and a third degree polynomial of radiation. RH appeared to have a preventing effect on the new particle formation whereas the effects of O3 and radiation were more conductive. The concentration of SO2 and NO2 also appeared to have significant effect on the emergence of nucleation events but because of the great amount of missing observation, we had to exclude them from the final analysis | ||
