A SLR Pre-Processing Algorithm Based on Satellite Signature Effect [PDF]

open access: yesApplied Sciences, 2021
As one of the major error sources, satellite signature effect should be reduced or even erased from the distribution of the post-fit residuals to improve the ranging precision.

Reduction of Satellite Signature Effect in High-Accuracy Satellite Laser Ranging to Etalon [PDF]

open access: yesApplied Sciences, 2023
Etalon is considered to be one of the most promising satellites for studying crustal motions, Earth rotation, and other scientific applications. Unfortunately, its outsized shape and signature result in a measurement range bias of several millimeters. On

Estimation of multiple inflows and effective channel by assimilation of multi-satellite hydraulic signatures: The ungauged anabranching Negro river [PDF]

open access: yesJournal of Hydrology, 2020
With the upcoming SWOT satellite mission, which should provide spatially dense river surface elevation, width and slope observations globally, comes the opportunity to assimilate such data into hydrodynamic models, from the reach scale to the hydrographic network scale. Based on the HiVDI (Hierarchical Variational Discharge Inversion) modeling strategy
