This data came to me from Peter Bloomfield and was used in a paper concerning periodically correlated time series by Bloomfield, Robert Lund and myself. The MATLAB script reads the data and calls some MATLAB functions you do not yet have. Data points not available are filled with the value 999. The sample rate is monthly.
