Summary
Abstract: Core angular momentum (CAM) is estimated by Jault 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 on modelling hypotheses and data used for model
computations are available at the following URL:
