Specifying the values of delta factor for the Dolgoe Ledovo permanent gravity station

Continuous long-term highly precise gravity measurements at the Dolgoe Ledovo gravity station operated by the Schmidt Institute of Physics of the Earth, Russian Academy of Sciences, are carried out. The long-term time series of tidal corrections are obtained, and the values of the delta factor are specified for this station, which enables the correct intercomparison of the absolute gravity instruments.
