Measurement and Application of Isotopes and Organic Tracers in Atmosphere

Dear Colleagues,

Air pollution and global warming pose serious threats to human health and the environment, yet knowledge regarding these two issues remains limited. Organic tracers (PAHs, anhydrosugar, dicarboxylic acids, alkanoic acids, etc.) and isotopes (Δ¹⁴C, δ¹³C, δ¹⁵N, δ¹⁸O, δ³⁴S, etc.) are powerful tools for investigating sources, atmospheric processing, and the budget of atmospheric pollutants (e.g., carbonaceous aerosols, nitrate, sulfate, ammonia, and volatile organic compounds) and greenhouse gases (e.g., carbon dioxide, methane, and nitrous oxide). The measurements of specific tracers and isotopes can significantly improve our understanding of the environmental and climatic effects from anthropogenic activities and thus will provide fundamental scientific supports for the mitigation strategies of air quality.

In view of the above, this Special Issue aims to collect the latest original research and review papers on the studies of atmospheric pollutants and greenhouse gases. The topics of interest include, but are not limited to, the following:

• analysis techniques of isotopes and organic tracers in atmosphere
• source apportionment and atmospheric processing of air pollutants and greenhouse gases using the measurements of isotopes and source-specific tracers
• characteristics of isotopes and organic tracers in emission sources (e.g., biomass burning, industry emission and vehicular exhaust)
• identification of oxidation paths and aging processes for key air pollutants (e.g., sulfate, nitrate, primary and secondary 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 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.
