Special Issue Information
Dear Colleagues,
Optical propagation through the Earth’s atmosphere is exploited by several fields including, for example, free-space optical communications and optical astronomy. Optical turbulence in the Earth’s atmosphere causes a distortion of the wavefront and leads to detrimental performance of these systems.
In free-space optical communications, optical turbulence leads to beam broadening and wander, ultimately resulting in reduced signal, increased fade events and increased bit-error-rates. This is particularly true in strong turbulence conditions over large horizontal distances or links between the ground and orbiting satellites.
In astronomy, the optical turbulence severely degrades the angular resolution. Without correction, these aberrations reduce the world’s largest telescope to ‘light buckets’.
In both applications, adaptive optics systems can be used to correct for the detrimental effects of the optical turbulence. The performance of these systems is fundamentally limited by the temporal and spatial structure as well as the magnitude of the turbulence. Therefore, high-fidelity measuring, forecasting and modelling is essential to the design and operation of these systems.
Optical turbulence is a dynamic and complex process, making measurements, models, forecasts and correction an active and interdisciplinary research area with significant overlap between the topics. In this Special Issue, we invite colleagues working in this active and important area to submit ground-breaking articles and to help to create an interdisciplinary knowledge base of the state-of-the-art developments in the field.

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.
