title = "Different Representations of the Time Variable Gravity Field to Reduce the Aliasing Problem in GRACE Data Analysis",
abstract = "The projected accuracy of the GRACE satellite mission has not been reached yet. One reason among others is the inaccurate modelling of the temporal variations in the analysis procedure by monthly or weekly mean fields, which can be shown in a simple simulation scenario. Two approaches to improve the temporal modeling are presented here: on the one hand the representation in terms of continuous temporal basis functions and on the other hand the increase of the temporal resolution to daily gravity field solutions by the use of the Kalman filter approach.",
