For each of the EAM time series (AAM, OAM, HAM, SLAM) 6-day forecasts are generated using atmospheric forecast from ECMWF. In addition, 90-day EAM predictions are calculated by combining AAM, OAM, HAM, SLAM.

Figures: Prediction error RMS (over 550 individual predictions) for polar motion and DUT1 compared to IERS C04. From top to bottom: x-pole, y-pole, pole, DUT1. Orange: Bulletin A, Blue: ESMGFZ.
