For further improvements of gravity field models based on Gravity Recovery and Climate Experiment (GRACE) observations. it is necessary to identify the error sources within the recovery process. Observation residuals obtained during the gravity field recovery contain most of the measurement and modeling errors and thus can be considered a realization of actual errors.
