Coestimating long-term temporal signals to reduce the aliasing effect in parametric geodetic mean dynamic topography estimation
Brockmann, Jan Martin; Borlinghaus, Moritz; Neyers, Christian; Schuh, Wolf-Dieter (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 ... -
Design of frequency selective filters for non-equispaced data
Schuh, Wolf-Dieter; Franken, Jessica; Brockmann, Jan Martin; Esch, Christina; Köhler, Joël; Gutjahr, Karlheinz (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. ... -
An improved global gravity field model from the GOCE mission: the time-wise release 6 model
Brockmann, Jan Martin; Schubert, Till; Mayer-Guerr, Torsten; Schuh, Wolf-Dieter (2019)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
Brockmann, Jan Martin; Schubert, Till; Schuh, Wolf-Dieter; Kvas, Andreas; Mayer-Guerr, Torsten (2019)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 ... -
Modeling of inhomogeneous spatio-temporal signals by least squares collocation
Schuh, Wolf-Dieter; Korte, Johannes; Schubert, Till; Brockmann, Jan Martin (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 ... -
On high performance computing in geodesy: applications in global gravity field determination
Brockmann, Jan Martin (2015)Autonomously working sensor platforms deliver an increasing amount of precise data sets, which are often usable in geodetic applications. Due to the volume and quality, models determined from the data can be parameterized ... -
Stochastic modeling of altimetric sea surface height measurements - refined AR models from iterative residual analysis
Brockmann, Jan Martin; Schuh, Wolf-Dieter (2016) -
Towards the Development of a Continuous Spatio-Temporal Finite Element Based Representation of the Mean Sea Surface
Borlinghaus, Moritz; Neyers, Christian; Brockmann, Jan Martin (2022)The mean sea surface has an important role both in the calculation of the mean dynamic topography and in the area of sea level change as a reference surface. This paper presents a new approach to estimate a continuous ...
