Dear colleagues I am very pleased to announce that there is a Special Issue on the joint 20th International EISCAT Symposium and 15th International Workshop on Layered Phenomena in the Mesopause Region. Although focused on the joint meeting, this Special Issue is open to all colleagues who are working in the relevant areas. https://www.annales-geophysicae.net/articles_and_preprints/scheduled_sis.ht… Authors can submit their contributions by using the online registration form on the ANGEO website: https://www.annales-geophysicae.net/submission.html. The deadline for submission is 1 Jul 2023, but may be extended if there is sufficient demand/need. During the registration process it is important that the correct special issue is selected. All submissions will be treated exactly the same as a regular submission to Annales, maintaining the highest quality of rigorous peer review and editorial standards. Papers will be published on-line as they become available and will form a digital collection. Thus there is no delay to publication once you have satisfied the reviewers and editors. Obviously we would hope to capture a good number of papers detailing work presented at the joint workshop, but at the same time other relevant work is very welcome and the special issue is not limited to those who were able to attend the meeting, as described on the website: "It is intended that this special issue would provide a snapshot of the state of the art in EISCAT and LPMR research, and as such the call is open to all colleagues working in these areas, even if they were not able to attend the joint meeting. As long as your work is related to EISCAT and/or layered phenomena in the mesosphere, you are welcome to submit an article."
