Volatile Organic Compounds (VOCs): Measurement, Monitoring, and Impacts on Air Quality

Dear Colleagues,

Volatile organic compounds (VOCs) play central roles in atmospheric chemistry, air quality, climate forcing, and human health exposure. However, large uncertainties remain in their emission profile, chemical transformations, and fate, particularly for reactive and oxygenated VOCs emitted from anthropogenic and biogenic sources. Improved measurements and monitoring strategies are therefore essential for constraining source contributions, evaluating air quality models, and designing effective control policies.

This Special Issue focuses on advances in the measurement and monitoring of VOCs across indoor and outdoor environments and over a wide range of temporal and spatial scales. We invite field, laboratory, and modeling studies that address key topics including: development and intercomparison of analytical techniques; in situ and remote-sensing observations; long-term monitoring networks; source apportionment and emission inventory evaluation; VOC reactivity and radical budgets; and the impact of VOCs in ozone and secondary organic aerosol formation. We particularly encourage studies that integrate multi-platform observations (ground-based, tower, aircraft, satellite), novel data analysis or machine learning approaches, and policy-relevant applications. Together, these contributions will provide an updated picture of VOC measurement capabilities and help identify priorities for future research and regulatory strategies.

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.
