Time-series of monthly gravity fields derived from GRACE observations (2002-2017) and continued by GRACE-FO (science phase starting in January 2019) are a major source for studies on large scale mass transport in the system Earth and for quantification of the effects of climate change. But up to date there is not one correct, agreed upon way of processing the satellite gravimetric observables, but a number of approaches that result in an equal number of time-series. We present a comparison, validation and combination of the latest of these time-series, based on the recent RL03 of the GRACE-L1B observation data. A focus will be laid on the effect of different background modeling strategies on the resulting gravity field models. The validation and combination are performed in the frame of the Combination Service for Time-variable Gravity models (COST-G), a new product center of the International Association of Geodesy (IAG).
