> Strasbourg Superconducting Gravimeters
Since 1996, temporal gravity variations have been permanently recorded near Strasbourg, first with the
the GWR-CO26 (1996-2018) and
the GWR-iGrav #029 (since 2016) instruments.
You can access here different IGETS products, for the iGrav #029 instrument also available at the
IGETS database, i.e.:
the 1-minute raw gravity and pressure
the 1-minute corrected gravity and pressure, ready for tidal analysis (Level-2)
produced by EOST,
the 1-minute gravity residuals (Level-3) produced by EOST.
The description of the formats/products can be found
