[G07-P-06] The Data Base of the International Geodynamics and Earth Tide Service (IGETS)
The International Geodynamics and Earth Tide Service (IGETS) was established in 2015 by IAG. IGETS continues the activities of the Global Geodynamics Project (GGP, 1997-2015) to support geodetic and geophysical research activities using superconducting gravimeter data in an international network. IGETS provides time series to monitor temporal variations of the Earth's gravity field and surface deformation by long term records from ground gravimeters, tiltmeters, strainmeters and other geodynamic sensors. IGETS also continues the activities of the International Center for Earth Tides (ICET) in collecting, archiving and distributing Earth tide records of various geodynamic sensors.
The IGETS data base is hosted by GFZ and is accessible via http://igets.gfz-potsdam.de to the geodetic and geodynamics community as well as to all other interested data producers and users. At present, records from superconducting gravimeters at 34 stations worldwide are available. Level 1 products are raw gravity and local air pressure records with 1 minute sample rate. As a new feature, records with 1 or 2 seconds samples are already provided for a few stations. Level 2 products consist of gravity and air pressure data corrected for instrumental perturbations and ready for tidal analysis, which are derived from Level 1 datasets and computed by the University of French Polynesia. Residual time series after geophysical corrections considered as Level 3 products are derived from Level 2 datasets and computed by EOST.
A major benefit of IGETS is the provision of digital object identifiers (DOI) for the data sets of every station. This ensures a long term availability and an increased visibility as part of an international network but also a proper citation. As IGETS is aiming to present all kind of long-term geodynamic time series, interested station operators are cordially invited to contribute with their data sets and, in return, benefit from being part of the IAG service.
