2 fields are missing (from June 12th to July 1st), due to accelerometer gaps.

2011/07/22: 7 new gravity fields models are available, covering February 2nd to April 12th 2011.
4 fields are missing (from December 24th to February 1st), due to accelerometer gaps.

2011/04/07: 12 new gravity fields models are available, covering August 26th to December 23rd 2010.
We now also provide grids in GRACE format (3 columns file), and images in polar projection.
We have corrected two bugs in our files:

  • the grids in GRGS format had a small amplitude problem, the amplitudes were exagerated by a factor between 0 % at low latitudes up to 10 % at high latitudes ;
  • the dealiasing products were not corrected for the Love load numbers and therefore didn’t take into account the loading effect.

These two bugs are now corrected. SH models (coefficients) were not affected by these problems.
