Following the successful 2nd EOP PCC Workshops (No. 1 in 2022 and No. 2 in 2023), we plan to organize another meeting devoted to the broadly defined topic of EOP forecasting and related aspects. The initiative is motivated by the sustained interest in EOP forecast evaluation within the 2nd EOP PCC and EOP PML, the rapid development of advanced forecasting methods, progress in modeling the impact of geophysical fluid layers on Earth’s rotation, and the activity of the new IERS Working Group on the Prediction of Earth Orientation Parameters (PEOP).
The meeting will provide an excellent opportunity to:
(1) summarize activities carried out within the post-operational phase of the 2nd EOP PCC campaign, particularly its EOP PML sub-campaign dedicated to machine learning-based forecasting methods;
(2) discuss future actions within the 2nd EOP PCC, EOP PML, and IERS Working Group on PEOP;
(3) engage in scientific discussions on recent developments in EOP determination, prediction, and interpretation.
We invite all interested researchers, not only EOP PCC participants and members of the IERS WG, to take part in the Workshop and submit abstracts. We welcome contributions on all topics related to the determination, analysis, and prediction of EOP, as well as discussions on reference solutions for EOP prediction validation, effective angular momentum analyses, and other relevant subjects. A dedicated session for discussion and feedback from 2nd EOP PCC participants is also planned.
Workshop will be held online. The workshop is scheduled for one day, Thursday, 9 April 2026, from 15:00 to 18:00 CEST (13:00 to 16:00 UTC).
Participants registration
The deadline to register is 3 April 2026. Please use the registration form to complete your registration.
Abstract submission
There is no abstract submission fee. We kindly ask to submit abstracts of the presentations using abstract submission form.
The abstract submission deadline is 23 March 2026.
Following information should be included in the abstract: title of presentation, author(s), affiliation(s) of author(s), and abstract text. The abstract body should have 100–300 words. Please do not include figures and equations in the abstract text. Abstract should be submitted via abstract submission form by main author. In individual cases abstracts might be also submitted by email. Each author can submit more than one abstract.
Please note that submission of an abstract does not mean registration for the Workshop. To participate in the Workshop, one needs to register via separate registration form.
Workshop programme
The programme is available here.
The workshop will be held via WebEx. Link to the meeting will be sent to registered participants shortly before the workshop (on Tuesday/Wednesday).
Data protection
Contact data of the participants of the 2nd EOP PCC Workshop No. 3 (i.e. names, affiliations and email addresses) will be used only by Workshop organizers to plan the conference and will not be publicly available or shared with third parties.
