Special Issue Information
Dear Colleagues,
Sulfur dioxide (SO2) is a crucial metric for understanding and managing atmospheric pollution, linking source strength and emission variability to atmospheric dispersion, oxidation pathways, sulfate formation, and wet and dry deposition, ultimately shaping downwind air quality.
Quantifying the source-to-impact pathway still presents a challenge. SO2 plumes evolve within highly variable boundary-layer regimes, including stability transitions, inversions, coastal circulations, and complex terrain. Additionally, chemical transformation depends on oxidant availability, humidity, cloud processing, and heterogeneous reactions that differ markedly across different spatial and temporal scales. These complexities propagate uncertainty into model-based assessments of exposure and impacts. They often reveal structural gaps between what monitoring stations capture and what models represent, such as grid-averaged processes, sub-grid plume dynamics, parameterized chemistry, and deposition.
This Special Issue aims to consolidate new advances and integrative approaches that enable the robust tracking of atmospheric SO2 across various scales from sources and emissions to dispersion, SO2 oxidation, and downwind impacts. We welcome contributions spanning field observations, remote sensing, laboratory and chamber experiments, and numerical modeling that improve process understanding and strengthen model evaluation.

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-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.
