Special Issue Information
Dear Colleagues,
Oxygenated volatile organic compounds (OVOCs) and biogenic volatile organic compounds (BVOCs) are precursors of the tropospheric ozone (O3) and secondary organic aerosols (SOA) on a regional and global scale due to their high photochemical reactivity. OVOCs encompass compounds that are composed of carbonyl or hydroxyl functional groups, which play a dual role in the photochemical cycle. They undergo photolysis to generate hydroxyl radicals, which influence the oxidation capability of the atmosphere. It should be noted that OVOCs can be emitted from both primary anthropogenic sources and formed from secondary formation. Tracking their origins and contributions is, therefore, challenging in the source apportionment.
BVOCs are known to be produced from different high-plant tissues in the tropics. The physiological process is another pathway for their formations. They contain diverse chemicals, including isoprene, terpenes, alkanes, alkenes, carbonyls, alcohols, acids, and esters. The massive variety of BVOCs signifies one of the biodiversity treasures of our planet. BVOCs have attracted increasing interest due to their participation in climate warming. Evidence proves that the production and emission of BVOCs might confer protection against high temperatures.
We invite authors to submit original and review articles that describe the experimental, field, and modeling studies related to detailed analyses of OVOCs and BVOCs. Any advancements in sampling techniques or the development of new instrumentation for the collection and analysis of OVOCs and BVOCs are welcome. Research should also focus on their source apportionment and the evaluation of potential health and ecological risks.

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.
