Special Issue Information

Dear Colleagues,

In the atmosphere, there exist many “criteria air pollutants” (e.g., ozone, PM2.5), which are harmful to the health of human beings and the environment under a high-concentration condition. Among them, ozone is a unique trace gas in the atmosphere. Unlike the role it has in the stratosphere protecting the biosphere of the earth, ozone in the troposphere is a kind of pollutant, which directly endangers the ecological environment and human health. Ozone in the troposphere also participates in photochemical reactions and thus dominates the oxidation ability of the atmosphere.

Although there exist many studies on ozone pollution, it was found in previous model studies that the simulation results frequently deviate from observations, which might be caused by: (i) an incomplete description of the ozone chemistry by chemical mechanisms; (ii) uncertainties in emission inventories; (iii) inaccurate treatment of the interaction between ozone and other atmospheric constituents such as PM2.5; and (iv) the influence of complex terrain and underlying surface properties.

Original papers (including review articles) investigating ozone pollution on the topics discussed above and many other relevant topics, focusing on the modeling of ozone and its precursors in urban, rural, and background environments, are welcome for this Special Issue.

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 2000 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.

In recent years, ozone and PM2.5 pollution has often occured in the Fenwei Plain due to heavy emission and favorable geographical conditions. In this study, we used the weather research and forecasting/chemistry (WRF-Chem) model to reproduce the complex air pollution of the ozone and PM2.5 in the Fenwei Plain (FWP) from 20 May to 29 May 2015. By comparing the simulation results with the observed data, we found that although in some cities there was a bias between the simulated values and observed data, the model captured the trend of pollutants generally. Moreover, according to the assessment parameters, we validated that the deviations are acceptable. However, according to these parameters, we found that the WRF-Chem performed better on ozone simulation rather than PM2.5. Based on the validation, we further analyzed the pollutant distribution during the contaminated period. Generally speaking, the polluted area is mainly located in the cities of the Shanxi province and Henan province. Moreover, in this time period, pollution mainly occurred on 27 May and 28 May. In addition, due to different formation conditions of ozone and PM2.5 pollution, the distribution characteristics of these two pollutants were also found to be different. Ozone pollution mainly occurred north of FWP due to the prevailing wind and the chemistry of ozone production. As for PM2.5, the pollution occurred at night and the polluted area was located in the FWP. Furthermore, high PM2.5 areas were closed to emission sources in the FWP, showing a high correlation with primary emissions. Full article
