CHAMP and GRACE resonances, and the gravity field of the Earth

Our main success has been for the 31/2 resonance, including the implicit 62/4, but in all cases our lumped values agree well with values based on the complete CHAMP and GRACE high-degree global gravity models (Eigen-3p and Eigen-Grace02s, respectively), though essentially independent of them. This confirms both the validity of our method and the high quality of the new global models.
