Short summary
In the Paris region, a campaign was conducted to study wet deposition of aerosol particles during rainfall events. Simultaneous measurements of aerosol and wet deposition allowed us to discuss their transfer from the atmosphere to rain. Chemical evolution within events revealed meteorology, atmospheric conditions and local vs. long range sources as key factors. This study highlights the variability of wet deposition and the need to consider event-specific factors to understand its mechanisms.
