I. Data

  1. core flows and angular momentum derived from computations constrained by the observed surface magnetic field and its secular variation
  2. LOD series with atmospheric contribution subtracted (from R. Holme and O. de Viron, Geomagnetic jerks and a high-resolution lenght-of-day profile, Geophys. J. Int., in press)
