Abstract
The catalogue named HW95 of the harmonic development of the Earth tide generating potential due to the Moon, the Sun and the planets Venus, Jupiter, Mars, Mercury and Saturn is presented here. This catalogue of the fully normalized potential coefficients contains 12935 waves, including 1483 waves due to the direct planetary effects (Hartmann and Wenzel 1994a,b). It is based on the DE200 numerical ephemerides of the planets and the Moon between the years 1850 and 2150. The error of gravity tides computed from the catalogue HW95 at mid‐latitude stations between the years 1850 and 2150 is estimated to about 1.4 (12.3) pm/s² rms (at maximum) in time domain and 0.002 (0.11) pm/s² rms (at maximum) in frequency domain (1 pm/s²=10−12 m/s²=0.1 ngal) using a new bench‐mark tidal gravity series (Wenzel 1996). An improvement in accuracy of a factor of 50 over the catalogues of Tamura (1987) and Xi (1989) has been achieved.
