文摘

A comparative analysis of predicted values of delta factors and phase shifts of eight major tidal waves obtained using a newly developed domestic tidal prediction software ATLANTIDA3.1_2014, their observed values, and values calculated using the PREDICT software from the ETERNA3.4 package, averaging over nine oceanic tidal models, is carried out. According to various criteria, the results returned by our software proved to be on average closer to the observations on 14 superconducting gravimeters of the GGP network than the results calculated by the PREDICT software. It is shown that this result is obtained both by the use of a more modern oceanic tidal model (FES2012) and a new model of the variation of amplitude delta factors with latitude (Spiridonov, 2014a).
