Gravity Field Analysis from the Satellite Missions CHAMP and GOCE
This work describes global gravity field modeling from observations of the CHAMP and the GOCE satellite mission. In the case of CHAMP the so-called Energy Balance Approach is applied to measurements of GPS high-low tracking of the low orbiting CHAMP spacecraft. In the case of GOCE gravity gradiometry is the main observable. The experience gained processing real data of the CHAMP satellite missi...
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 کاملValidation of GOCE global gravity eld models using terrestrial gravity data in Norway
The GOCE (Gravity eld and steady-state Ocean Circulation Explorer) satellite gravity gradiometry mission maps the Earth’s gravity eld. Harmonic analysis of GOCE observations provides a global gravity eldmodel (GGFM). Three theoretical strategies, namely the direct, the space-wise and the time-wise approach, have been proposed for GOCE harmonic analysis. Based on these threemethods, several GGFM...
متن کاملExpected Contributions of Dedicated Satellite Gravity Field Missions to Regional Geoid Determination with some Examples from Australia
Global models of the Earth’s gravitational field can be divided among three primary classes: satellite-only, combined and tailored models. Some of the current deficiencies in some of these models will be outlined using examples over Australia. The new dedicated satellite gravity field missions (e.g., GRACE, CHAMP and GOCE) will make significant improvements to the long-wavelength, satellite-der...
