The IERS/IAG/IAU Working Group on EOP Prediction focuses on comparing and assessing the accuracy, reliability, and robustness of Earth Orientation Parameters (EOP) predictions from different centers. It also evaluates the quality of Effective Angular Momentum forecasts essential for EOP prediction, verifies the accuracy of final EOP estimates, and analyzes both stationary and non-stationary uncertainties in present-day EOP predictions. Additionally, the group explores opportunities to integrate EOP predictions from various institutions.
The objectives of the Working Group on Climate Variability and Climate Change in EOP are exploring temporal limits of predictability of individual Earth orientation parameters with (partially) coupled climate models, quantification of contributions from various components of the (anthropogenically altered) Earth’s system to rotational variations on time-scales from days to centennials, assessment of angular momentum budgets of global numerical climate and Earth system models.
We would like to discuss ongoing activities, future plans, and suggestions for improvement within the groups.
