Preliminary CSR GRACE RL07 re-processing results

The fifteen and half years long GRACE temporal gravity data has greatly contributed to interdisciplinary studies especially in climate and solid Earth sciences. To further improve the noise level and error characteristic of the GRACE temporal gravity solutions, as well as provide an archival record for supporting a multidecade mass change measurement based on measurement continuity between the GRACE and GRACE Follow-On mission, the GRACE RL07 re-processing has been carried out at CSR. We will use an initial version of the GRACE Level1B  data (i.e. version 04P), updated background models, new GPS observation strategy and improved observation noise model for the RL07 re-processing. In this poster, we will present preliminary results from the GRACE RL07 re-processing and compare them with the GRACE RL06 solutions using different metrics.
