Abstract—The study estimates the impact level of storm microseisms on long-term gravimetric measurements. The gravimetric measurements were conducted at the Zapolskoe, Obninsk, and Murmansk sites using CG-5 Autograv relative gravity meters. seismic measurements were conducted simultaneously with the gravimetric measurements at Zapolskoe. The analysis of these measurements has demonstrated the feasibility of using seismic data as control information to estimate the high-frequency noise component in gravimetric data. Additional seismic information was taken from the services of the Incorporated Research Institutions for Seismology. The analysis of these data established that the attenuation of the noise component in gravimetric measurements is consistent with the data from the modeled sensitive element of the gravimeter, which utilizes seismic series as an input. The first characterization of the storm-induced background noise in gravimetric measurements at the Murmansk site is obtained. Also, the possibility of predicting measurement errors based on meteorological forecasts is ascertained, which can aid in the planning of gravimetric work.
