Version Release 05

GRACE Tellus Monthly Mass Grids provides monthly
gravitational anomalies relative to a 2004-2010 time-mean baseline.
The data contained in this dataset are units of “Equivalent Water Thickness”
which represent the deviations of mass in terms of vertical extent
of water in centimeters. See the provider’s Monthly Mass
Grids Overview

for more details.

The GRACE Tellus (GRCTellus) Monthly Mass Grids dataset is produced
by three centers: CSR (U. Texas / Center for Space Research),
GFZ (GeoForschungsZentrum Potsdam), and JPL
(NASA Jet Propulsion Laboratory). Each center is a part
of the GRACE Ground System and generates Level-2 data
(spherical harmonic fields) used in this dataset.
The output includes spherical harmonic coefficients
of the gravity field and of the dealiasing fields used to compute them.
Since each center independently produces the coefficients, the results
may be slightly different. It is recommended for most users to
use the mean of all three datasets. See the provider’s choosing a
for more details.


  • Due to the sampling and post-processing of GRACE observations,
    surface mass variations at small spatial scales tend to be attenuated.
    Therefore, users should multiply the GRCTellus Land data by the
    scaling grid available at

  • The GRCTellus Land grids processed from the Spherical Harmonic
    Level-2 data are not suited to accurately quantify ice mass
    changes over Greenland or Antarctica, or glaciers and ice caps.
    For those areas it is recommended to use JPL’s mascon
    solution available as the following image collection:
