Special Issue Information

Dear Colleagues,

A better understanding of the chemical and meteorological processes that contribute to the source and transport of ozone is needed to improve cost-effective control strategies and accurate air quality forecasting capabilities. This Special Issue, Source and Transport of Ozone, solicits papers in the areas of:

1) Sources of background ozone production (both natural and anthropogenic), such as fossil fuel emissions from both regional and global regions, lightning, convection, biomass burning, wildfires, and stratosphere-to-troposphere transport episodes.

2) Enhancement of ozone concentrations through photochemical reactions, primarily from precursor emissions of nitrogen oxides and non-methane reactive organic gases within the polluted atmospheric boundary layer.

3) Ozone source and transport and detrimental effects on agriculture, vegetation, and terrestrial ecosystems.

4) Long-range-transported background ozone and its influence on surface ozone.

5) Meteorological impact on ozone transport and their interactions.

6) Change in ozone transport pathways and characteristics associated with climate change, as well as global and regional ozone trend analysis.

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.

Tropospheric ozone (O3) is highly variable over space and time reflecting local production and destruction as well as addition and loss through regional and long-range transport. In this study, O3 concentrations at 11 stations in Ireland and their long-term trends (7–9 sites) were evaluated; O3 concentrations (2015–2019) varied spatially, with the highest annual mean concentrations along the Atlantic west coast (69–75 µg/m3), and the lowest in urban centres (39–43 µg/m3). Ozone followed a seasonal pattern of spring and winter maximum and summer–autumn minimum. Significant long-term (2005–2019) increases were observed in annual O3 concentration at two rural stations, while increases were larger and more frequent during winter with increases at four out of seven stations. During the decade 2010–2019, significant annual increases were observed at four out of nine stations. Observed site- and season-specific increasing trends in O3 concentrations likely reflected changes in regional precursor gas emissions sources. Despite reported decreases in background concentrations in the marine boundary layer in northern mid-latitudes in recent decades, O3 concentrations at some sites in Ireland have increased significantly primarily driven by changes in winter concentrations. There were no significant decreasing trends at any site or in any season. Full article
