Abstract
Tidal strain observations carried out in the Sopronbánfalva Geodynamic Observatory (SGO) in Hungary are used to test thirteen different ocean tide loading models for diurnal and semi-diurnal tidal harmonic constituents O1, K1 and M2. Strain data with one minute sampling rate were corrected for temperature and barometric pressure and decimated to one hour sampling rate.
Highlights
Ocean tide surface loading causes both radial and tangential displacements of the Earth surface and changes of gravity
Various authors have been dealing with testing and comparison of recent global ocean tide models on the basis of gravimetric [6,7,8,9,10,11,12,13,14,15,16,17], displacement (GPS) [18,19,20,21,22,23,24,25], extensometric [15,16,26,27] and tilt measurements [28,29,30]
The efficiency of ocean loading corrections are compared using thirteen different ocean tide loading models for the diurnal and semi-diurnal tidal harmonic constituents O1, K1 and M2 on the basis of strain data observed in the Sopronbánfalva Geodynamic Observatory (SGO) in 2017
