Properties of the Gravity Fields of Terrestrial Planets
The gravity fields of Earth, Venus, and Mars have recently been reanalysed more thoroughly by Lerch et al (1992) and Smith and Nerem (1992), extending the spherical harmonic expansions to appreciably higher degrees. It is therefore timely to examine the properties of the three planetary gravity fields, as expressed by these harmonic coefficients. Necessary auxiliaries to this examination are the harmonic expansions of the planetary topographies, by Balmino et al (1973), Bills and Ferrari (1978), and Bills and Kobrick (1985).
