Interaction of aerosols with clouds

One of the department’s current research areas is the topic of wet deposition of atmospheric aerosol by horizontal hydrometeors (e.g. fog, clouds). The research uses experimental data measured at the Milešovka observatory, where these hydrometeors occur for most of the year (225 out of 365 days). The data consist of particle number size distributions with sizes ranging from 10 nm to 20 μm, distribution of hydrometeors of sizes from 3 to 50 μm, and sizes and concentrations of drops larger than 0.16 mm, all determined before, during, and after hydrometeor exposure. The properties of the aerosol are examined both without the influence of hydrometeors and during their action. This will allow us to assess the impact of these hydrometeors on the aerosol, depending on particle number size distribution and its origin and modeled sources, and also on the properties of the hydrometeors.
