Warning: MEAN POLE MODEL
Since there has been a change on February 1st 2018, in the IERS conventions, on the definition of the mean pole model (Section 7.1.4 has been rewritten to include the secular pole and remove the former quadratic mean pole), the time series of GRACE spherical harmonic solutions from CNES/GRGS are provided in both the old IERS2010 convention (quadratic mean pole) and in the new one (linear mean pole). Only the C(2,1) and S(2,1) coefficients differ between the two versions.

Reference fields used to compute the grids:
Here is the static reference field used to compute the geoid and equivalent water height grids:
This static field corresponds to the average field at the middle of the data span, i.e. 2008/09.
Mean gravity field model EIGEN-GRGS.RL04.MEAN-FIELD
A mean gravity field model containing a time-variable gravity (TVG) part up to degree and order 90 has been computed from the GRGS-RL04-v1 monthly time series of solutions. It can be found here: GRACE format / ICGEM-V2 format
