Permanent gravimetric network data
The Résif gravity data are time series of gravity and atmospheric pressure variations measured by superconducting gravimeters at four sites in mainland France (Larzac, Rustrel, Strasbourg and Trappes in France), and repeated measurements at about twenty sites by the different French absolute gravimeters.
Data from the permanent gravity stations of Résif Level 1 (raw data), Level 2 (data pre-processed to allow tidal analyses) and Level 3 (residuals after geophysical corrections) are available through the International Geodetic Association (IGA) International Services Data Centres:
- the International Geodynamics and Earth Tide Service (Igets)
- the Igets server, hosted by the GFZ in Potsdam, Germany. The data are accessible there in the form of monthly text files of time series per second and per minute. Contents: date, time, gravity, pressure…

Mobile network stations data
Data from the mobile network stations are distributed by the International Gravimetric Bureau (IGB), the scientific service of the IAG mandated to compile, validate, archive and make all relative or absolute measurements of the Earth’s gravity field (terrestrial, marine, airborne measurements) available to the scientific community .
IAG website disseminates the point gravity data (relative and absolute measurements) acquired by the French teams.
