Monthly mass change fields from GRACE and GRACE-FO  CSR RL06 GSM solutions.

Time Span: Apr. 2002 - Apr. 2020
Sampling Rate: Monthly, 184 Solutions (with 173 GRACE R06 solutions and 21 GRACE-FO solutions)
Grids: 1 x 1 Degree (180x360 grids, -89.5 to 89.5 degree latitude, and 0.5 to 359.5 degree longitude)
Decorrelation + 500 or 300 km Gaussian Smoothing
Truncation at degree 60 
C20 and C30 coefficients are replaced by SLR estimates (TN14), and geocenter variations are included (TN13).

Name Conventions:
dm_gsm_300p4m6_r06_200204_201608.mat   - P4M6 Decorrelation + 300km Gaussian smoothing

The time steps (in year) are given in the "t6_184.mat" file, and the units for mass change are in cm of equivalent water height change.
