Special Issue Information
Dear Colleagues,
Atmospheric dynamic processes are driving the coupling between the different atmospheric layers. An improved characterization of these processes is crucial to a better understanding of the role that infrasound and acoustic-gravity waves play in the coupled Earth’s crust–ocean–atmosphere system, up to the ionosphere, where manifestations of physical processes occurring in the ocean, the crust, and the lower atmosphere can be detected.
The field of infrasonic research, i.e., the science of low-frequency acoustic waves, has expanded to include acoustic-gravity waves and has developed into a broad interdisciplinary field encompassing academic disciplines of geophysics and recent technical and fundamental scientific developments. Recent studies have offered new insights on quantitative relationships between infrasonic observations and atmospheric dynamics and therefore open a new field for atmospheric remote sensing.
New studies using lidar, radar, microwave spectrometery, and mesospheric airglow observations complemented by satellite measurements help to better determine the interaction between atmospheric layers from the ground to the mesosphere and the influence of atmospheric waves on the mean flow. It is expected that further developing multi-instrument platforms would support the improvement of gravity wave parameterizations and enlarge the science community interested in operational infrasound monitoring.
In a higher frequency range, infrasound monitoring systems also offer a unique opportunity to provide, in near-real time, continuous relevant information about natural hazards with high societal impact, such as large volcanic eruptions, surface earthquakes, meteorites, and severe weather.
In this Special Issue, linked to the homonym session AS1.6 at the EGU General Assembly 2022 (https://meetingorganizer.copernicus.org/EGU22/session/43909), we encourage research papers covering the above-mentioned aspects or similar studies of infrasound, acoustic-gravity waves, and relevant atmospheric dynamic processes such as sudden stratospheric warmings, planetary waves, atmospheric tides, etc. Results and advances in data processing, propagation modelling, and innovative instrumentation, which also encompasses the extension of regional array networks as well as the utilization of infrasound for monitoring of extreme events, are welcome.

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. Remote Sensing is an international peer-reviewed open access semimonthly 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 2700 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.
