The following files are provided:
For CSR release 5 GRACE gravity field trends for the time period 02/2003 to 10/2009 are provided.
1) StokesPerYear_GRACE_CSR90_NoSmbCorr_SwensonAndGauss200Filtered.geoid.llz
Rate of geoid-height change [mm/yr] (column 3) on regular 0.25°x0.25° geographic grid (Column 1: longitude; column 2 latitude), Swenson & Wahr 2006 filtering + 200 km Gaussian smoothing
2) StokesPerYear_GRACE_CSR90_NoSmbCorr_SwensonAndGauss200Filtered.mass.llz
Rate of equivalent water-height change [mm/yr] (column 3) on regular 0.25°x0.25° geographic grid (column 1: longitude; column 2 latitude), Swenson & Wahr 2006 filtering + 200 km Gaussian smoothing

3) StokesPerYear_GRACE_CSR90_NoSmbCorr_SwensonAndGauss200Filtered.potential_coeff.kff
Rate of the GRACE gravitational potential coefficients [1/yr] as spectrum, Swenson & Wahr 2006 filtering + 200 km Gaussian smoothing (column 1: degree, n, column 2: order, m, column 3: cos_nm; column 4: sin_nm)
4) StokesPerYear_GRACE_CSR90_NoSmbCorr_Unfiltered.potential_coeff.kff
Same as 3) but without filtering applied.

Remaining files 5)-8) analogue, but for GFZ release 5.

All data are provided to spherical-harmonic degree and order 90.
