# A New Reference Equipotential Surface, and Reference Ellipsoid for the Planet Mars

@article{Ardalan2009ANR, title={A New Reference Equipotential Surface, and Reference Ellipsoid for the Planet Mars}, author={Alireza Azmoudeh Ardalan and Roohollah Karimi and Erik W. Grafarend}, journal={Earth, Moon, and Planets}, year={2009}, volume={106}, pages={1-13} }

Using the shape model of Mars GTM090AA in terms of spherical harmonics complete to degree and order 90 and gravitational field model of Mars GGM2BC80 in terms of spherical harmonics complete to degree and order 80, both from Mars Global Surveyor (MGS) mission, the geometry (shape) and gravity potential value of reference equipotential surface of Mars (Areoid) are computed based on a constrained optimization problem. In this paper, the Areoid is defined as a reference equipotential surface…
