Summary
Abstract: Core angular momentum (CAM) is estimated by Petrov et al. using
modelling hypotheses applied to magnetic data. CAM is then
transformed into change in the length of day (LOD). Data is expressed
as excess length of day in milliseconds over a standard day of 86400
seconds.

Details for the modelling hypotheses and data used in model
calculations are available at the following URL:
