Dear Colleagues,

Ammonia (NH₃) is the most prevalent alkaline gas in Earth’s atmosphere. It is receiving recent renewed attention due to its implication in enhancing new particle formation (NPF), the conversion of condensible gases to particles, and subsequent growth to larger aerosols through gas-particle partitioning interactions with acid precursor gas (SO₂ and NO_x) products. NH₃ plays multiple other roles in the atmospheric environment by virtue of its alkalinity, reactivity, solubility, and abundance. Ammonia emissions from agricultural, industrial, municipal waste and transportation sources continue to grow. Thus, we are still developing an understanding of ammonia’s role and impact on the atmospheric environment, climate, and human and ecosystem health.

In recognition of these uncertainties and the importance of atmospheric ammonia, the open-access journals Atmosphere and IJERPH are jointly hosting a Special Issue to highlight the most recent findings related to quantification, emissions, modeling and mitigation of NH₃ and its impacts on air quality, aerosol properties, nitrogen deposition, and broadly for climate and health. Toward this, we invite original results utilizing in situ and/or remote sensing measurements from laboratory studies, field measurements, network monitoring, aircraft campaigns, satellite inferences or theoretical/model studies and reviews across scales ranging from the quantum to the atmosphere. Studies synergizing multi-platform measurements and modeling as well as epidemiological studies are especially welcome.

You may choose our Joint Special Issue in IJERPH.

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.
