The oceanic component of Earth Orientation parameters (polar motion and length of day) estimated from a 1/12 degree global ocean general circulation model (NEMO-ORCA12). The data includes separate mass and motion components of polar motion (Chi1 & Chi2) and length of day (Chi3). The detailed information regarding the data is provided in the ASCII file.
