Friday October 5th 2018: RL04-v1 available

Our new release RL04-v1 is now available!

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.
