Currently a reprocessing of the LUH GRACE monthly gravity field solutions is carried out at our institute. The new processing chain utilizes updated background models, parametrization and outlier detection. This processing chain is consistent with the approach currently applied for our operational GRACE-FO time series. In this contribution, we present our gravity field recovery strategy. The reprocessed time series is compared to the previous LUH GRACE series as well as to the most recent series of other GRACE analysis centers. We present a comparison of the noise behavior (in terms of residual signal over the oceans), signal content (river basin amplitudes, regional mass trends) and low degree coefficients. In addition, post-fit range-rate residuals are inspected.
