Keywords:Geodesy, Gravity and Geoid, Airborne gravimetry

We present the conputational results of gravimetric geoid over Colorado using airborne gravity data. The gravity data and degital elevation model were provided by IAG JWG2.2.2 with the colaboration of National Geodetic Survey. Here we show the gravimetric geoid based on the two Stokes-Helmert approaches, i.e. the classical approach (Moritz, 1980) and UNB approach (Vanicek et al., 2013).
