Following concerns surrounding atmospheric fine particle (PM2.5, particulate matter with aerodynamic diameter smaller than 2.5 μm) pollution, the role of ammonia (NH3) emission mitigation in reducing PM2.5 formation has attracted increasing attention worldwide. NH3 is a major alkaline gas in the atmosphere and can react with sulfuric acid and nitrate acid, the oxidized products of sulfur dioxide (SO2) and nitrogen oxides (NOx), and form secondary PM2.5 as ammonium sulfate and ammonium nitrate. Ammonia is mainly emitted from agricultural cropland and livestock manure, with a small proportion being from non-agricultural emission. Therefore, it is extremely important to identify NH3 emission and mitigation potentials, from both agricultural and non-agricultural sources, in order to meet the stricter future PM2.5 environmental thresholds (e.g., 10-25 μg/m3).
Considering this scientific background, the open-access journal Atmosphere is hosting a Special Issue to showcase the most recent findings related to agricultural ammonia emission, mitigation techniques from fertilized croplands and livestock farms, and effects of ammonia mitigation on PM2.5 reduction. This Special Issue is, of course, an appropriate venue for papers that deal with social–economic and health benefits of PM2.5 pollution improvement induced by NH3 mitigation and other associated resource reuse activities. Furthermore, this Special Issue aims to showcase the most successful case studies on regional NH3 mitigation actions in the globe.
Original results from field experiments and controlled investigations, models, and review papers in relation to NH3 emission, mitigation, and PM2.5 pollution reduction are all welcome contributions. Authors are also encouraged to write a viewpoint paper on future requirements on agricultural nitrogen management and NH3 mitigation by 2050 or 2100.

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.
