time-variable gravity determination from the grace gravity solutions filtered by tikhonov regularization in sobolev subspace
the grace mission has provided scientific community time-variable gravity field solutions with high precision and on a global scale. the grace mission was launched on march 2003. this mission consists of two satellites that pursue each other in their orbit. distance between two satellites in orbit is measured continuously to an accuracy of better than 1 micron using kbr system placed in satelli...
متن کاملStatistical downscaling of GRACE gravity satellite-derived groundwater level data
With the continued threat from climate change, population growth and followed by increasing water demand, the need for hydrological data with high spatial resolution and proper time coverage to be felt more than ago. Therefore, having data such as terrestrial water storage changes and groundwater level changes with high resolution spatial helps to plan and make decisions for water resource mana...
متن کاملApproximate decorrelation and non-isotropic smoothing of time-variable GRACE-type gravity field models
Wediscuss a newmethod for approximately decorrelating andnon-isotropically filtering themonthly gravity fields provided by the gravity recovery and climate experiment (GRACE) twin-satellite mission. The procedure is more efficient than conventional Gaussiantype isotropic filters in reducing stripes and spurious patterns, while retaining the signal magnitudes. One of the problems that users of G...
متن کاملThe potential of ground gravity measurements to validate GRACE data
New satellite missions are returning high precision, time-varying, satellite measurements of the Earth’s gravity field. The GRACE mission is now in its calibration/validation phase and first results of the gravity field solutions are imminent. We consider here the possibility of external validation using data from the superconducting gravimeters in the European sub-array of the Global Geodynami...
متن کاملAIUB-RL02: an improved time-series of monthly gravity fields from GRACE data
S U M M A R Y The new release AIUB-RL02 of monthly gravity models from GRACE GPS and K-Band range-rate data is based on reprocessed satellite orbits referring to the reference frame IGb08. The release is consistent with the IERS2010 conventions. Improvements with respect to its predecessor AIUB-RL01 include the use of reprocessed (RL02) GRACE observations, new atmosphere and ocean dealiasing pr...
