The harmonic analysis of tidal model time series

The harmonic analysis of tides is reviewed and guidelines for the analysis of tidal model time series are presented. The analysis technique introduced by Godin and circulated by Foreman is summarized. The related issues of constituent selection, time series length, confidence regions, and inference are discussed. It is shown that since numerical model time series have a much lower non-tidal content than observational time series, constituents can be separated with shorter record lengths.
