Time-lapse gravimetry (repeat microgravity measurement) is a powerful tool for monitoring temporal mass distribution variations, including seasonal and long-term groundwater storage changes (GWSC). This geophysical method measuring in gravity (?g) potentially applicable to any system. Here, I present Gravi4GW, Python the site-adapted calculation of ?, conversion factor between ?g GWSC (also kno...

We report an airborne gravity survey with absolute gravimeter based on atom interferometry and two relative gravimeters: a classical LaCoste\&Romberg (L\&R) novel iMAR strap-down Inertial Measurement Unit (IMU). estimated measurement errors for the quantum ranging from 0.6 to 1.3 mGal depending flight conditions filtering used. Similar are obtained strapdown but long term stability is five time...

The network of more than 24 superconducting gravimeters (SGs) of the Global Geodynamics Project (GGP) is available as a set of reference stations for studies related to time-varying gravimetry. The inherent stability of the SG allows it to detect signals from a sampling time of 1 s up to periods of several years with a time-domain accuracy of 0.1μGal or better. SGs within the GGP network compri...
