Connections Between the Deep Interior and Atmosphere
A One-Day COFFIES Virtual Workshop
Visit our YouTube playlist to watch the recordings of each session from the Workshop!
September 26th, 2025 on Zoom
Registration is open
The NASA COFFIES DRIVE Center invites abstract submissions for the COFFIES Virtual Workshop on Connections Between the Deep Interior and Atmosphere, to be held online on Friday September 26th, 2025, from 8:30 am to 2:30 pm PT (11:30 pm - 5:30 pm ET; 3:30 pm - 9:30 pm UT).
The workshop will feature two invited talks to set the scene and will have three sessions of contributed content. The objective of the workshop is to:
- facilitate a discussion on how best to improve our understanding of the physical connections between the Sun’s convective interior and atmosphere over multiple spatial and temporal scales (from the tachocline to the low solar atmosphere), and
- foster multi-disciplinary collaborations between observers, modelers, and theorists to address these challenges and better understand solar activity and the solar cycle dynamo.
We welcome contributions from all interested researchers. To register and/or request a contributed talk, please fill out the linked form below.
A Zoom link will be sent out to registered attendees prior to the meeting.
Deadline for registration and contributions is Tuesday, September 16, 2025.
We’d like to thank our organizers: Bill Abbett, Aimee Norton, and Bhishek Manek, as well as all speakers and participants!
