DOI: 10.1002/2017gl072668
Abstract: Density anomalies beneath the lithosphere are expected to generate dynamic topography at the Earth's surface due to the induced mantle flow stresses which scale linearly with density anomalies, while the viscosity of the upper mantle… read more here.

DOI: 10.1002/2017gl073777
Abstract: New-generation synthetic aperture radar altimetry, as implemented on CryoSat-2, observes sea surface heights in coastal areas that were previously not monitored by conventional altimetry. Therefore, CryoSat-2 is expected to improve the coastal mean dynamic topography… read more here.

DOI: 10.1002/2017gl076020
Abstract: In geodesy, coastal Mean Dynamic Topography (MDT) was traditionally determined by spirit levelling technique. Advances in navigation satellite positioning (e.g., GPS) and geoid determination enable space-based levelling with an accuracy of about 3 cm at… read more here.

DOI: 10.1016/j.asr.2020.07.042
Abstract: Abstract The filtering procedure is usually mandatory for computing the mean dynamic topography (MDT) by combining the mean sea surface (MSS) and geoid due to the inconsistent spectral contents between them. Recently, a rigorous fusion… read more here.
