Abstract

In this article we highlight the advances in gravity field recovery with CHAMP and GRACE, leading to the new GFZ release 04 (RL04) EIGEN (European Improved Gravity field of the Earth by New techniques) models. RL04 consists of time series of monthly CHAMP and GRACE gravity models, pure weekly GRACE solutions and combined static fields from satellite-only and terrestrial data. Additionally a new mean CHAMP-only gravity field model has been generated. It becomes obvious that the improvements in the RL04 background modelling, processing standards and strategies have led to significant improvements in the reprocessed gravity field models. These new RL04 EIGEN models, available for nearly the whole CHAMP and GRACE mission periods, provide an important data base to monitor mass transport and mass distribution phenomena in the system Earth, such as the continental hydrological cycle, ice mass loss in Antarctica and Greenland, ocean mass changes or the ocean surface topography.
