Special Issue Information

Dear Colleagues,

The formation of air pollution is generally a synergy of anthropogenic emissions and unfavourable weather conditions, as well as contributions of regional transport. Therefore, the air quality of a region is not only determined by local sources but also substantially influenced by trans-boundary transport of air pollutants from adjacent areas, which is controlled by multi-scale synoptic systems. Accurate identification and quantitative source apportionment of air pollutants provide an important prerequisite for the design and implementation of emission control strategies to improve air pollution. This Special Issue aims to quantitatively evaluate the contribution of trans-boundary transport of air pollutants to the air quality in a polluted region under specific weather conditions and separate the contribution of local emissions and trans-boundary transport of air pollutants to air quality under different pollution levels. Topics of specific interest include, but are not limited to, the following:

  1. Analysis of the pathway of air pollutants;
  2. The effect of weather conditions on the transport of air pollutants;
  3. Contribution of trans-boundary of air pollutants to air quality;
  4. Development of a source-oriented model;
  5. Identify the contribution of trans-boundary of air pollutants under different pollution level;
  6. Joint prevention and control 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 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.

Arizona, a rapidly growing state in the southwestern U.S., faces ozone pollution challenges, including nonattainment areas in Yuma and Maricopa counties influenced by neighboring state pollution transport. In this study, we use five-year (2017–2021) hourly back-trajectories and O3 concentration data for concentration-weighted trajectory (CWT) analysis to identify transport pathways and potential source regions of O3 at six monitoring sites in Arizona. We divide the data into five seasons (winter, spring, dry summer, monsoon summer, and fall) to examine variations in O3 concentration and transport across sites and seasons. The highest mean O3 concentrations occur during spring (37–49 ppb), dry summer (39–51 ppb), and monsoon summer (34–49 ppb), while winter (19–41 ppb) exhibits the lowest seasonal mean. The CWT results reveal that high O3 concentrations (≥40 ppb) in Arizona, with the exception of Phoenix and Tucson sites, are influenced significantly by regional and international transport, especially in spring (14.9–35.4%) and dry summer (12.7–26.9%). The major potential source areas (excluding the Phoenix and Tucson sites) are predominantly located outside Arizona. This study highlights the critical role of pollution transport in influencing O3 variability within Arizona and will be valuable in shaping pollution control strategies in the future. Full article
