Abstract
After publishing its release 04 (RL04) time-series of monthly GRACE gravity field solutions starting end of 2006, GFZ has reprocessed this time-series based on numerous changes covering reprocessed instrument data, observation and background models as well as updated processing environment and standards. The resulting GFZ RL05 time-series features significant improvements of about a factor of two compared to its precursor. By analyzing 72 monthly solutions for the time span 2005 till 2010, a remarkable noise reduction and a noticeably higher spatial resolution become obvious. The error level has significantly decreased and is now only about a factor of six above the pre-launch simulated baseline accuracy. GFZ RL05 solutions are publically available at ISDC and PO.DAAC archives.
