Considering the actual error of residual KBR data, it is feasible to accurately compute the gravimetric observables directly from band-pass filtered residual range-rate and range-acceleration data, and employ them for analyses concerning the regional time-variable gravity field of the Earth such as continental hydrology.]]> Tue 18 Oct 2022 14:55:33 AEDT ]]> GRACE gravitational measurements of tsunamis after the 2004, 2010, and 2011 great earthquakes https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:40035 2. There is good agreement between GRACE measurements and tsunami models for the three events. Complementarily to buoys, ocean bottom pressure sounders, and satellite altimeters, GRACE is sensitive to the long-wavelength spatial scale of tsunamis and provides an independent source of information for assessing alternate early earthquake and tsunami models. Our study demonstrates an innovative way of applying GRACE and GRACE Follow-On data to detect transient geophysical mass changes which cannot be observed by the conventional monthly Level-2 and mascon solutions.]]> Fri 15 Jul 2022 10:11:21 AEST ]]>
