CNES/GRGS RL05 daily gravity solutions (spherical harmonic coefficients) obtained from a 10-day sliding window and a Tikhonov-stabilized SVD inversion between August 2002 and August 2024.
The daily GRACE/GRACE-FO normal equations were accumulated in 10-day batches, together with their two associated 5-day SLR normal equations, and then solved by Tikhonov-stabilized SVD inversion. The batch was then shifted by one day, and the process repeated. This yields a series of 10-day gravity solutions with daily temporal resolution.
The 10-day-sliding-window solution can be downloaded from the Catalogue page (look for « GSM » products).
