Discussion

Analysis reveals systematic disturbances in dual sphere superconducting gravimeters, indicating complexities in gravity measurements.

Dual sphere superconducting gravimeters reveal systematic instrumental disturbances through sensor differences.
Relative drift between sensors and unexpected drift rate changes were observed, lasting several months.
Analysis included data from the International Geodynamics and Earth Tide Service database for comprehensive insights.
Understanding these disturbances is crucial for studying gravity changes linked to hydrology and polar motion.

Beck et al. (2025) studied this question.
