Popis: We use Mixture Density Networks (MDN) to estimate atmospheric particle size distributions based upon metrological parameters. Measurements of particle size spectra show that distributions are often multi-modal, composed of various underlying aerosol species that can grow from one mode to another. The flexibility of the MDN allows for the prediction of an arbitrary distribution. We show here that the MDN prediction engine can be useful in forecasting complicated, multi-modal particle size distributions. To inform and train the MDN we use meteorological, particle size and optical extinction measurements taken from a three week propagation measurement field campaign.
