Special Issue Information

Dear Colleagues,

The emission of gases at the surface impacts the atmosphere as a whole, from the ground to the upper thermosphere. There is a deep interest in the determination of the induced changes in the stratosphere, mesosphere and lower thermosphere (SMLT) composition and temperature, and the understanding of coupling processes with other atmospheric regions, feedback mechanisms and interactions with climate. Variations in atmospheric constituents affect the energy budget, modifying temperatures and, ultimately, the extension of the atmosphere. They may also eventually alter the dynamics and phenomena propagating from and to other regions in the atmosphere. Changes of anthropogenic origin are superimposed to the considerable natural variability of this atmospheric region. Above all else, all these are interconnected and interaction between large-scale processes and the regional behavior also play a role.

Over the past decades, spaceborne and groundbased instrumentation have provided a wealth of observations of the SMLT. These have allowed for an unprecedented perception of the variability in the SMLT composition and thermal structure at multiple timescales, the interconnection with lower and upper regions and the influence of the solar cycle. Nonetheless, the portrait of the changes in this region is not univocal. This is in part due to limitations in the observations, which lead to sampling biases and disagreements between instruments.

This Special Issue calls for papers addressing the study of the SMLT temperature and composition and providing insights on variations at any timescale and their evolution from an observational perspective, either from space, from the ground or from a combination of them, and either at a local or a global scale. Discussions on effects from sampling biases and other sources of uncertainties are more than welcome. Contributions may cover any of the following topics:

- SMLT monitoring, climatologies, observational evidence for long-term changes, identification of drivers;
- Characterization of diurnal, seasonal and interannual variability and their evolution;
- Effect of gravity waves, planetary waves and tides and its evolution;
- Influence of the sun on SMLT variability;
- SMLT coupling processes with lower and upper atmospheric regions and their variability;
- Comparisons between instruments, determination of sampling biases and uncertainties, effect on the interpretation of variabilities at any timescale;
- Role of natural variability in secular trends, impact of short and mid-term variations on long-term trend estimates.

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 papers will be 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 1400 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.
