RECENT PUBLICATIONS

“Measuring 1-mm-accurate local survey ties over kilometer baselines at McDonald Geodetic Observatory“, was recently published in the Journal of Geodesy by the Center’s Jullian Rivera, Srinivas Bettadpur, Zhigui Kang, and John Ries with John Griffin. Abstract: The goal for the next generation of terrestrial reference frames (TRF) is to achieve a 1-mm- and 0.1-mm/yr-accurate frame realization ...

Figure 3: Changes in sea ice and land ice in the polar regions from ICESat and ICESat-2.Main maps show sea ice thickness for the Arctic and Greenland region (sea ice thickness for January 202064) and the Antarctic region (average for April to November 2019)82 from ICESat-2. The height change rate for the land ice sheet ...

“Monitoring Coastal Waves with ICESat-2“, was recently published in the Journal of Marine Science and Engineering by the Center’s James Dietrich and Matt Holwill characterizing coastal waves with ICESat-2. Abstract: The coastal zone faces an ever-growing risk associated with climate-driven change, including sea level rise and increased frequency of extreme natural hazards. Often the location and ...

A new paper, “Modeling Uncertainty of GEDI Clear-Sky Terrain Height Retrievals Using a Mixture Density Network”, was recently published in the Special Issue of Remote Sensing and Ecosystem Modeling for Nature-Based Solutions by The University of Texas Center for Space Research Ph.D student, Jonathan Sipps, about innovative solutions for remote sensing analytics using machine learning ...

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, ...
