Atmospheric Deposition: New Insights into an Important Self-Cleaning Process in Atmosphere with Environmental Consequences

Dear Colleagues,

Atmospheric deposition is an important process contributing to the self-cleaning of the atmosphere and introducing not only nutrients but also pollutants into the ecosystems and environment. This indeed crucial process involves different mechanisms influenced by numerous factors, such as the capacity and spatial distribution of both natural and anthropogenic emission sources, meteorological processes, atmospheric chemistry, land use and ecosystems. It occurs via wet or dry pathways, the first one being an episodic process related to rain and snow events, whereas the latter one is a continuous direct transfer of gases and particles to the Earth´s surface. Occult deposition, related to fog and rime, is mostly neglected due to the lack of data, though it is known to contribute substantially to the total deposition fluxes in certain areas, such as mountain forests.

The infamous acid deposition, a result of the long-range transport of air pollutants such as sulphur dioxide and nitrogen oxides from highly polluted emission source areas, resulted in vast damages both in terrestrial and water ecosystems in the fairly clean Scandinavia as well as in the Northeastern US in the 1970s. Due to stringent emission reductions the acid deposition has substantially improved since in Europe and the US; however, it has become a challenge in other parts of the world, such as Southeast Asia, due to its fast growing population and related activities.

This Special Issue seeks manuscripts presenting new insights into both wet and dry deposition pathways and processes from different world regions and environments. We invite you to contribute articles by reporting on observation-based and modelling studies, related not only to wet and dry, but to occult deposition as well. Contributions elucidating the deposition of major ions and trace elements, both inorganic and organic species, are encouraged. Studies considering the role of on-going climate change in atmospheric deposition processes are gladly accepted. Both original research studies and review articles are welcome.

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 submissions that pass pre-check are 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 250 words) can be sent to the Editorial Office for assessment.

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-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Atmosphere is an international peer-reviewed open access monthly 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 2400 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.
