Ozone in Stratosphere and Its Relation to Stratospheric Dynamics

Dear Colleagues,

Ozone is a very important trace gas in the stratosphere because its protects biota from harmful solar radiation. The amount of ozone is given not only by ozone chemistry but also by stratospheric dynamics. Nowadays, the concentration of ozone-depleted substances is decreasing, which has a positive impact on the ozone concentration. On the other hand, the stratospheric dynamics are influenced by global warming, which plays an important role in the behavior of ozone in the stratosphere. We also observe the acceleration of Brewer–Dobson circulation, which transports the ozone from the tropics to a polar latitude together with a decrease in stratospheric temperatures due to global warming. An increase in tropopause height is also present. Changes in the propagation of planetary waves are seen in the stratosphere. The recovery of the ozone layer is expected in the future, but its date is uncertain depending on the model used. There are also model differences, which could be the matter of research. Stratospheric dynamics also have an influence on the troposphere, so vertical coupling between the troposphere and stratosphere is observed.

All of these phenomena lead to an interesting situation in the behaviour of the stratospheric ozone; this behaviour will be the central topic of a Special Issue of Atmosphere. The basic topics of this Special Issue are the following: the relationship between ozone chemistry and dynamics in the statosphere, the influence of ozone to statosphere–troposphere coupling, and the influence of global warming on the stratospheric dynamics and ozone concentration.  Similar topics are also suitable 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 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.
