Atmospheric Organic Aerosols: Source, Formation and Light Absorption

Dear Colleagues,

Organic aerosols, consisting of a wide range of organic compounds, have gained significant attention due to their diverse sources and potential impact on the air quality and climate. This Special Issue aims to bring together research that investigates the sources and formation processes of organic aerosols, as well as their light-absorbing properties. By doing so, we hope to advance our understanding of their contribution to radiative forcing and their implications for atmospheric processes and human health. The scope of this Special Issue encompasses a broad range of research areas related to atmospheric organic aerosols. We welcome submissions on the identification and characterization of organic aerosol sources, such as anthropogenic emissions, biogenic emissions, and secondary organic aerosol formation. Additionally, investigations into the chemical and physical properties of organic aerosols, their transformation and aging processes, and their interactions with other atmospheric constituents are encouraged. Furthermore, studies focusing on the quantification and modeling of light absorption by organic aerosols are of particular interest.

Topics of interest for the Special Issue include, but are not limited to

• Sources of organic aerosols: Investigating the contributions of anthropogenic emissions, such as vehicle exhaust and industrial processes, as well as natural emissions from vegetation and wildfires.
• Formation mechanisms of organic aerosols: Understanding the chemical and physical processes involved in the formation of secondary organic aerosols (SOA) from precursor gases in the atmosphere.
• Chemical and physical properties: Characterizing the composition, size distribution, hygroscopicity, and volatility of organic aerosols to better understand their behavior and interactions with other aerosol components.
• Light absorption by organic aerosols: Quantifying the optical properties of organic aerosols and their contributions to radiative forcing, both regionally and globally.
• Impacts on air quality and climate: Assessing the effects of organic aerosols on air pollution, visibility, cloud formation, and climate change, and developing strategies for its mitigation and management.

We invite researchers from various disciplines to contribute their original research articles, reviews, or perspectives to this Special Issue. We look forward to your valuable contributions as we strive to deepen our knowledge and promote a comprehensive understanding of atmospheric organic aerosols.

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.
