Validation of static gravity field models using GRACE K-band ranging and GOCE gradiometry data

The ability of satellite gravimetry data to validate global static models of the Earth’s gravity field is studied. Two types of data are considered: K-band ranging (KBR) data from the Gravity Recovery and Climate Experiment (GRACE) mission and Satellite Gravity Gradiometry (SGG) data from the GOCE (Gravity field and steady-state Ocean...

Detectability of groundwater storage change within the Great Lakes Water Basin using GRACE

Groundwater is a primary hydrological reservoir of the Great Lakes Water Basin (GLB), which is an important region to both Canada and US in terms of culture, society and economy. Due to insufficient observations, there is a knowledge gap about groundwater storage variation and its interaction with the Great Lakes. The objective of this study is...

Identification and Modeling of Sea Level Change Contributors: On GRACE satellite gravity data and their applications to climate monitoring

Since early 2002, the Gravity Recovery and Climate Experiment (GRACE) twin satellite mission provide the scientific community with accurate monthly maps of the Earth's gravity field. On short time-scale, the observed variations are mainly related to a redistribution of water on the Earth's surface. This new data set has lead to a leap forward in...

Shallow-earth rheology from glacial isostasy and satellite gravity: A sensitivity analysis for GOCE

In recent years, satellite gravity missions have been launched that probe the earth's long- to mediumwavelength (1000 - 500 km) gravity field. The upcoming ESA satellite gravity mission GOCE is predicted to measure the gravity field with an accuracy of a few centimeters at spatial scales of 100 km. Such a high-resolution gravity field contains...
