Special Issue Information
Dear Colleagues,
The solar corona, the outermost layer of the Sun's atmosphere, is a rich and dynamic region that has long been the subject of extensive scientific research. Understanding its complex structure and behaviour is crucial for advancing our knowledge of the Sun–Earth system, as it is the origin of the solar wind and the site of the most energetic phenomena, such as solar flares, coronal mass ejections, and solar energetic particle acceleration.
Significant progress in observing and characterising the solar corona has been achieved through a variety of ground-based instruments (i.e., LOFAR, EOVSA, ALMA, MLSO, SPO) as well as space missions (i.e., SOHO, STEREO, SDO, SO, PSP, Aditya-L1, ASO-S), providing different and complementary datasets for multidisciplinary research. Future instruments, such as Proba3 and SKA, promise to further advance our scientific knowledge about plasma processes and space weather services.
This Special Issue aims to deliver a comprehensive overview of the current status of solar coronal observations, highlighting key achievements, ongoing efforts, and emerging challenges. Contributions will focus on coronal heating mechanisms, the derivation of the coronal magnetic field, and the corona’s large-scale and fine structures. Emphasis will also be placed on energetic phenomena identification, modelling, and monitoring. Additionally, this Special Issue will address the limitations and uncertainties in current observational techniques, highlighting the need for further advancements in the adopted technologies, data analysis, and theoretical modelling. Topics include—but are not limited to—the need for higher spatial and temporal resolution, improved coronal plasma diagnostics, and a deeper understanding of the complex interplay between magnetic fields, plasma, and energy transport processes. A special focus will be devoted to integrating multi-wavelength data analysis with the development of comprehensive models to enhance our comprehension of solar coronal physics. Authors are encouraged to share novel ideas, results, and approaches to advance our knowledge in this 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.
