Mesosphere and Lower Thermosphere (2nd Edition)

Dear Colleagues,

This Special Issue is a follow-up of the first Special Issue entitled “Mesosphere and Lower Thermosphere” (https://www.mdpi.com/journal/atmosphere/special_issues/mesosphere_lower_thermosphere).

The MLT region is defined as the region of the atmosphere between about 45 and 105 km in altitude, which is very sensitive to external influences from the sun/ionosphere above and atmosphere below it. Chemical, momentum, and thermal balance, and thus basic states (i.e., pressure, density, temperature, and winds) of MLT can change in different time scales.

In the first issue, we focused on the dynamics and specific phenomena (e.g., sporadic E layers, polar mesosphere summer echo, irregularities, etc.) in the MLT. This follow-up issue will focus on ground-based, airborne, and space-borne observation techniques and instrumentation. Ground-based remote sensing detection technique, i.e., radar and LiDAR, are important observational instruments. Recent results regarding the development of air-borne and space-borne payloads for MLT are also welcome in this issue.

The MLT region is also important for aerospace engineering, especially for near-space hypersonic vehicles. In this issue, the effects of MLT atmospheric conditions on near-space hypersonic vehicles will also be discussed.

Authors are encouraged to submit original papers on topics including, but not limited to, observations, modeling, instrumentation, etc. Review papers and technical tutorials are also 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 250 words) can be sent to the Editorial Office for assessment.

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.
