Nineteenth EISCAT-3D User Meeting

EISCAT Scientific Association

20th EISCAT_3D User Meeting (2025_2)

The 19th E3D User Meeting (UM) will take place on Dec 2-3 (week 49). The meeting will start on Tuesday, Dec 2, after lunch. The meeting will end on Wednesday, Dec 3, before lunch. The UM will be hybrid, i.e. physical attendance is at the EISCAT/IRF (Aniara) in Kiruna, and online participation via Zoom.

Preliminary subjects of presentations/discussions are E3D data analysis, new generation
GUISDAP, E3D Common Programmes, and Visualization.

We'll stick to the traditional scheme with short presentations followed by questions and discussion. Submissions of titles/short abstracts are welcome. The web pages of previous meetings, 19th E3D UM and 18th E3D UM and earlier, can give an impression for the arrangements and programme which include in some cases links to the presentation slides.

This announcement was last updated on Dec 1, 2025.

Registration

Registration is by filling this Google form. Optionally preliminary titles of presentatons/posters and other comments can be filled. The names and email addresses of registered persons will be used to provide the Zoom link and other updates about the meeting by email. They will be stored as long as E3D User meetings are regularly held, unless specific removals are requested.

A list of registered colleagues is here.

Programme

Contributions on any E3D related subject can still be submitted. Especially encouraged are discussions of E3D and in general ISR data analysis, their data organization, profiles vs voxels, E3D Common Programmes, and Visualization. An ad-hoc programme committee of volunteers might be asked to help if many submissions are received and some need to be postponed to a later user meeting.

The Programme includes

* Update on EISCAT as an organisation
* EISCAT_3D Update and Plans
* IS Analysis and EISCAT_3D
* EISCAT_3D related Science

Practical Information

The workshop will take place at the IRF premises at the Rymdcampus in Kiruna. The campus can be reached by Länstrafiken Norrbotten bus 501. Online participation is via the Zoom tool licensed by IRF, i.e. there is no exchange of personal data such as names and email addresses with third parties. We do not intend to record the meeting but will make presentation slides publicly available also for some time after the meeting, if the presenters agree.
