For the first time daily gravity field snapshots have been derived from GRACE level 1B data using a Kalman smoother approach. When calculating independent solutions, such an extreme increase in temporal resolution would lead to a loss in redundancy and therefore to a decreasing accuracy of the estimated parameters with decreasing time span. It can be assumed, however, that the gravity field does not change arbitrarily from one day to the next. The information about the temporal correlation patterns has been derived from geophysical models (hydrology, atmosphere and ocean). This knowledge has been utilized within the framework of a Kalman smoother estimation procedure to enhance the temporal resolution without losing spatial information.
