Harmonic Analysis of Tides from Standard Observations of the Sea Level

G. N. Voinov

Peculiarities of harmonic analysis of tides by using standard observation data of the sea level with a 6-hourly time step are considered. Masking frequencies causing difficulties when interpreting the results of the data analysis are presented. A method of control and editing of standard observations by using a non-recursive filter is proposed. The data interpolation approach based on direct and inverse Fourier transformation is considered.
