An improved global gravity field model from the GOCE mission: the time-wise release 6 model
The Gravity field and steady-state Ocean Circulation Explorer (GOCE) completed its science mission to observethe Earth’s gravity field in 2013. From the collected observations, gravity gradients and tracking ...
An improved global gravity field model of the Earth derived from reprocessed GOCE observations with the time-wise approach
ESA's dedicated gravity field mission GOCE (Gravity field and steady-state Ocean Circulation Explorer) successfully completed its science operations in 2013 as the first Earth Explorer mission in orbit. In 2014, the fifth ...
Coestimating long-term temporal signals to reduce the aliasing effect in parametric geodetic mean dynamic topography estimation
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 ...
Modeling of inhomogeneous spatio-temporal signals by least squares collocation
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 ...
Design of frequency selective filters for non-equispaced data
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. ...
