Greenland Mass Trend
A regional mass trend estimate parameterized by radial basis functions has been computed from GRACE level 1B observations for the Greenland area. The processing strategy follows the short arc approach, also applied in the computation of the ITG-Grace2010 time series.
Details:
- Time span: 2003-2011
- The solution is regularized with the optimal regularization parameter determined by variance component estimation
- The following background models were used during the data processing:
| Earth rotation | IERS 2003 |
| Moon, sun and planets ephem.: | JPL DE405 |
| Earth tide: | IERS 2003 |
| Ocean tide: | EOT11a |
| Pole tide | IERS 2003 |
| Atmosphere and Ocean Dealiasing: | AOD1B RL05 |
| Permanent tidal deformation: | included (zero tide) |
| Temporal variations: | annual and semi-annual signal from ITG-Grace2010 |
