Coestimating long-term temporal signals to reduce the aliasing effect in parametric geodetic mean dynamic topography estimation
(2022-06-16)
The geodetic estimation of the mean dynamic ocean topography (MDT) as the difference between the mean of the sea surface and the geoid remains, despite the simple relation, still a difficult task. Mainly, the spectral ...
A water storage reanalysis over the European continent: assimilation of GRACE data into a high-resolution hydrological model and validation
(2019-04-18)
Continental water storage and redistribution within the Earth’s system are key variables of the terrestrial water cycle. Changes in water storage and fluxes may affect resources for drinking water and irrigation, lead to ...
Automatic optimization of height network configurations for detection of surface deformations
(2013-05-18)
Levellings are performed to observe height changes of different epochs at discrete surveying points. A
reliable estimation of surface deformations by a bivariate polynomial needs a sufficient configuration of the underlying ...
Design of frequency selective filters for non-equispaced data
(2018-07-22)
Modern sensors and satellite missions deliver huge data sets and long time series of observations.
In the most cases equispaced time series are collected. Filtering of time series is a standard task in data analysis. ...
Modeling of inhomogeneous spatio-temporal signals by least squares collocation
(2022-06-16)
Through inverse modeling and adjustment techniques, the geodesists try to derive mathematical models from their measurements to get a better understanding of various processes in the system Earth. Sophisticated deterministic ...
