Time-derivative of \(g_1^0\) (left) and sensitivity \(s_1\) for GRACE-A as computed from Model-B and Model-C (right). For Model-C, we allowed nightside platform magnetometer data to contribute to the estimation of the internal \(g_1^0\) Gauss coefficient. The gap period between CHAMP and Swarm is indicated as a blue-shaded region (Sep 2010 to Nov 2013)
