The IGETS data base at GFZ Potsdam
IGETS is the International Geodynamics and Earth Tide Service of the International Association of Geodesy (IAG). The main objective of IGETS is to monitor temporal variations of the Earth gravity field through long‐term records from ground gravimeters, tiltmeters, strainmeters and other geodynamic sensors.
IGETS continues the activities of the Global Geodynamics Project (GGP) to provide support to geodetic and geophysical research activities using superconducting gravimeter (SG) data within the context of an international network. Furthermore, IGETS continues the activities of the International Center for Earth Tides (ICET), in particular, in collecting, archiving and distributing Earth tide records from long series of gravimeters, tiltmeters, strainmeters and other geodynamic sensors.
GFZ operates the IGETS data base of worldwide high precision SG records. The hosted products are:
- Raw gravity and local pressure records sampled at 1 or 2 seconds, in addition to the same records decimated at 1‐minute samples (Level 1 products).
- Gravity and pressure data corrected for instrumental perturbations, ready for tidal analysis. This product is derived from the previous datasets, and is computed by one or several Analysis Centers (Level 2 products).
- Gravity residuals after particular geophysical corrections (including solid Earth tides, polar motion, tidal and non‐tidal loading effects). This product is also derived from the previous dataset and is computed by one or several Analysis Centers (Level 3 products)
The access to the IGETS data base is password-protected and all data users have to register to get an account for data download. New data producers have to pass through a separate registration procedure. A detailed description of the IGETS data base, the IGETS products and the registration procedure for producers is available via the link Documentation.
