Tidal prediction using time series analysis of Buoy observations
Although tidal observations which are extracted from coastal tide gages, have higher accuracy due to their higher sampling rate, installing these types of gages can impose some spatial limitation since we cannot use every part of sea to install them. To solve this limitation, we can employ satellite altimetry observations. However, satellite altimetry observations have lower sampling rate. Acco...

Free core nutation resonance parameters from VLBI and superconducting gravimeter data
Context. The free core nutation (FCN) can be observed by its associated resonance effects on the forced nutations of the Earth’s figure axis, as observed by very long baseline interferometry (VLBI), or on the diurnal tidal waves, retrieved from the time-varying surface gravity recorded by superconducting gravimeters (SG). Aims. In this paper, we study the sensitivity of both techniques to the F...
متن کاملStudies of Earth Dynamics with the Superconducting Gravimeter
I present investigations of Earth dynamics with the superconducting gravimeter GWR T020 at Metsähovi from 1994 to 2005. As a necessary background, the history and key technical details of the installation are given. Then a new data acquisition system (DAS) developed by the author is described. It has proved reliable and accurate. A pre-requisite for the study of weak phenomena is the removal of...
متن کاملField test of the superconducting gravimeter as a hydrologic sensor.
We report on a field test of a transportable version of a superconducting gravimeter (SG) intended for groundwater storage monitoring. The test was conducted over a 6-month period at a site adjacent to a well in the recharge zone of the karstic Edwards Aquifer, a major groundwater resource in central Texas. The purpose of the study was to assess requirements for unattended operation of the SG i...
