AIUB-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...
متن کاملtime-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 کاملOn the postprocessing removal of correlated errors in GRACE temporal gravity field solutions
We revisit the empirical moving window filtering method of Swenson andWahr (GeophysResLett 33:L08402, 2006) and its variants, Chambers (Geophys Res Lett 33:L17603, 2006) and Chen et al. (Geophys Res Lett 34: L13302, 2007), for reducing the correlated errors in the Stokes coefficients (SCs) of the spherical harmonic expansion of the GRACE determined monthly geopotential solutions. Based on a com...
متن کاملGoce Gravity Field Processing
In the course of the satellite mission GOCE (Gravity field and steady-state Ocean Circulation Explorer), dedicated for the exploitation of the Earth's gravity field, with a planned launch in summer 2006, the data processing will be a huge numerical and computational intensive task. In this paper we will describe a direct approach developed and implemented in Graz for the derivation of a model f...
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...
