Special Issue Information
Dear Colleagues,
Ozone, particulate matter and atmospheric acids adversely affect human health, the environment and climate. Atmospheric gas-phase chemistry plays a critical role in determining the concentrations of these air pollutants. The gas-phase chemistry of the atmosphere is very complex. Much of the chemistry in the lower troposphere is dominated by the reactions of nitrogen oxides and volatile organic compounds. Sulfur dioxide and ammonia emissions also contribute to the formation of particulate matter. Atmospheric inorganic chemistry is relatively straightforward compared with the chemistry of volatile organic compounds. There are at least thousands of anthropogenic and biogenic organic compounds emitted. Each compound may form many other unique compounds and intermediates when it oxidizes in the atmosphere. Therefore, a complete gas-phase atmospheric chemical mechanism consists of on-the-order-of several million reactions and compounds. Now, there are important efforts to build highly detailed gas-phase mechanisms that attempt to be as complete as possible. However, many of the required reactions for highly detailed mechanisms must be constructed from structure–activity relationships. The development of highly detailed gas-phase mechanisms is a very valuable component of atmospheric chemistry research. On the other hand, more simplified gas-phase atmospheric chemical mechanisms are used in meteorological air quality models for making public policy. Both types of chemical mechanisms and their development procedures are of interest for this Special Issue. Methods of condensation, including machine learning and other approaches, used to link the development of simplified mechanisms to the highly detailed gas-phase mechanisms are of deep interest for this Special Issue.

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 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. 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.
