AB: The information theoretic approach to smoothing non-stationary time-series is presented incorporating B-splines with natural boundary conditions. This approach is applied to instrumental Northern Hemisphere annual mean time-series. In contrast to previous studies, the information theoretic approach provides rigorous objective criteria for choosing the model order and regularization parameter for optimal smoothing of climate time-series.
