Special Issue Information

Dear Colleagues,

Aerosol particles are an essential component of the atmosphere, with about 8000 MT of particulate matter produced or suspended in the troposphere each year. These particles contribute to air quality, soil fertilisation and cloud formation. By interacting with clouds, they contribute significantly to the water cycle and Earth’s radiation balance. One of the main sources of uncertainty in climate models is related to interactions between aerosols and clouds.

Wet deposition is one of the main mechanisms that limit the accumulation of aerosols particles in the atmosphere. It has two contributions: below- and in-cloud scavenging. Below-cloud scavenging is induced by the collection of aerosol particles by the hydrometeors (raindrops, hailstones, snowflakes, graupels, etc.). There are still large uncertainties regarding the collection efficiencies parameter, especially for solid hydrometeors. In-cloud scavenging is more complex to both understand and model, since it is the result of two paired processes. Aerosol particles are converted into cloud droplets (droplet activation process) or ice crystals (ice nucleation) depending on parcel temperature and physicochemical properties of the aerosol particles. Cloud might then produces precipitations that deposit the particles on the ground. Aerosol size, concentration, chemical composition, solubility, surface structure and electrical properties strongly affect rain formation, and, as a consequence, inflicts a substantial effect on the in-cloud scavenging.

This Special Issue aims to present works on the understanding of both in- and below-cloud scavenging. We invite authors to submit original articles on laboratory and field measurements, numerical simulations, and theoretical studies on microphysical processes leading to this important mechanism in the aerosol budget of the atmosphere.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2300 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
