TitleSupplementary data and code for ‘On smoothing potentially non-stationary climate time series’ (Geophysical Research Letters, Mann 2004)
AbstractA simple approach to the smoothing of a potentially non-stationary time series is presented which provides an optimal choice among three alternative, readily motivated and easily implemented boundary constraints. This method is applied to the smoothing of the instrumental Northern Hemisphere (NH) annual mean and coldseason North Atlantic Oscillation (NAO) time series, yielding an objective estimate of the smoothed decadalscale variations in these series including long-term trends.
