Strasbourg (EOST)

Since 1996, temporal gravity variations have been permanently recorded near Strasbourg, first with the GWR-T005 (1987-1996), 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 record (Level-1),
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 in the EOST products document.

GWR-iGrav #029 (since 2016)
