SNO gravimetrie

The SNO (Service National d'Observation) gravimetrie includes 2 main components :

(1) a contribution to international scientific services of IAG (International Association of Geodesy) including the Bureau Gravimétrique International (BGI, and the International Geodynamics and Earth Tide Service (IGETS, created respectively in 1951 and 2015, and both operating in France, and

(2) a contribution to the monitoring of temporal gravity variations performed from a set of permanent observatories hosting superconducting gravimeters and from repeated absolute gravity measurements in about 20 sites in France and worldwide.

Timeseries from 9 superconducting gravimeters, installed at 6 different sites, and repeated AG measurements (ResRef network) are provided:

Repeated AG data (ResRef)

We also include the time series of the 2 tiltmeters installed in Sainte-Croix-Aux-Mines in the Vosges mountains, with a temporal sampling of 15-seconds.
