Constraining the Internal Structures of Venus and Mars from the Gravity Response to Atmospheric Loading

Abstract The gravity fields of celestial bodies that possess an atmosphere are periodically perturbed by the redistribution fluid mass associated with atmospheric dynamics. A component this perturbation is due to gravitational response body deformation its surface induced pressure loading. magnitude effect depends on relation between loading and in terms geopotential variations measured load Love numbers. In work, we simulate analyze field generated atmospheres Venus Mars accounting for different models their internal structure. By precisely characterizing phenomena drive transportation through general circulation models, determine interior structure An accurate estimation time-varying field, which measures contribution, may provide significant constraints measurement combined determination tidal numbers would enhance our knowledge planetary bodies, providing further geophysical inversion models.
