As ice sheets and glaciers continue to lose mass, we expect sea levels to rise by different amounts around the world and even to fall near the ice sheets. Models predicting these patterns form the basis of future sea-level projections.  However, the patterns over large spatial scales have never been directly observed, as they were ...

CSR GRACE Follow-On group published the first global Earth gravity field models to be derived from space borne laser ranging interferometer, flown as a technology demonstration onboard the joint NASA/GFZ GRACE Follow-On mission. This paper is particularly significant because space geodesy is transitioning from using the microwave interferometric techniques (used on GRACE and GRACE-FO missions) ...

A group of researchers led by Dr. Jianli Chen at the Center for Space Research published a new study in Water Resources Research (https://doi.org/10.1029/2020WR028032). The Gravity Recovery and Climate Experiment (GRACE) satellite gravimetry provides a revolutionary means for monitoring and measuring global mass redistribution and movement with unprecedented accuracy. Combining GRACE observed terrestrial water storage ...

Dr. Bettadpur is one of the authors of a National Academies committee report that provides an assessment of the geodetic infrastructure needed for NASA to implement its next decade’s Earth Science plans. Dr. Bettadpur’s contribution to this report drew on the long-standing CSR contributions in the areas of space geodesy and space missions.

Dr. Jianli Chen, a Senior Research Scientist at the UT Center for Space Research led a new study published in the Journal of Geophysical Research . Variations of Earth rotation are ...

Researchers at the Seoul National University and UT Center for Space Research published a new joint study in the Geophysical Research Letters (https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2019GL085470). This study was led by Jae-Seung Kim, a graduate student of Dr. Ki-Weon Seo who has been a visiting scientist at UT CSR for the past year. During the last decade, the ...

Dr. Jianli Chen and a group of scientists at the Center for Space Research are the authors of a new study just published in the Geophysical Research Letters (https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2019GL085519). GRACE satellite gravimetry provides a revolutionary means for monitoring and measuring global mass redistribution and movement with unprecedented accuracy. The Integration of GRACE satellite gravity measurements, ...

Read about how GRACE Follow-On mission, launched in May 2018, is engineered, once again with contributions from UTCSR, to continue the unique measurements of the mass change in the Earth system. A description of the GRACE-FO mission and flight systems description was published online on April 26, 2019 (https://arc.aiaa.org/doi/10.2514/1.A34326). This mission continues the legacy of ...

GRACE, the US/German Gravity Recovery And Climate Experiment, was conceived, proposed and implemented under UTCSR leadership, with many staff and students over the years contributing to engineering and science data analysis. Since their launch in 2002, the twin GRACE satellites have revolutionized our understanding of mass transport in the Earth system using time-resolve satellite gravimetry. ...

Quantification of Ocean Mass Change Using GRACE Gravity, Satellite Altimeter and Argo Floats Observations, November 13, 2018, Dr. Jianli Chen and a group of scientists at the Center for Space Research are the authors of a study published in the Journal of Geophysical Research -Solid Earth. Combining satellite gravity measurements from the Gravity Recovery and ...
