The Combination Service for Time-Variable Gravity Fields (COST-G) is providing monthly gravity fields of the dedicated gravity missions GRACE and GRACE-FO, which are combined from the individual time-series of the COST-G associated and partner analysis centers (ACs). Recently, the operational GRACE-FO combination has been switched to the new RL06.1 time-series of the GRACE-FO science data system (SDS) ACs, which are based on JPL’s new accelerometer transplant product, and to AIUB-GRACE-FO-RL03, which makes use of empirical noise modelling techniques. Moreover, the COST-G weighting scheme was adapted according to the recommendation developed in the Horizon 2020 project Global Gravity-based Groundwater Product (G3P). The so-far existing COST-G GRACE-FO time-series has been re-combined and is now available as RL02. We analyse the quality improvement of the COST-G GRACE-FO RL02 wrt the RL01.
