Convergence of Daily GRACE Solutions and Models of Submonthly Ocean Bottom Pressure Variability
(Journal of Geophysical Research: Oceans, 2021-02-19)Knowledge of submonthly variability in ocean bottom pressure (pb) is an essential element in space‐geodetic analyses and global gravity field research. Estimates of these mass changes are typically drawn from numerical ... -
Gravitationally Consistent Mean Barystatic Sea Level Rise From Leakage‐Corrected Monthly GRACE Data
(Journal of Geophysical Research: Solid Earth, 2020-11-19)Gravitationally consistent solutions of the Sea Level Equation from leakage‐corrected monthly‐mean GFZ RL06 Gravity Recovery and Climate Experiment (GRACE) and GRACE Follow‐On (GRACE‐FO) Stokes coefficients reveal that ... -
Integrated processing of ground- and space-based GPS observations: improving GPS satellite orbits observed with sparse ground networks
(Journal of Geodesy, 2020-10-10)The precise orbit determination (POD) of Global Navigation Satellite System (GNSS) satellites and low Earth orbiters (LEOs) are usually performed independently. It is a potential way to improve the GNSS orbits by integrating ... -
Long-Term Wetting and Drying Trends in Land Water Storage Derived From GRACE and CMIP5 Models
(Journal of Geophysical Research: Atmospheres, 2019)Coupled climate models participating in the CMIP5 (Coupled Model Intercomparison Project Phase 5) exhibit a large intermodel spread in the representation of long-term trends in soil moisture and snow in response to ... -
New Methods for Linking Science Objectives to Remote Sensing Observations: A Concept Study Using Single- and Dual-Pair Satellite Gravimetry Architectures
(Earth and Space Science, 2020)In this manuscript, we present a new analysis tool, called space-time-accuracy grid (STAG) analysis, to simultaneously assess the performance of an observing system architecture across space and time. Such an analysis tool ... -
Non‐Tidal Background Modeling for Satellite Gravimetry Based on Operational ECWMF and ERA5 Reanalysis Data: AOD1B RL07
(Journal of Geophysical Research: Solid Earth, 2022-08-13)The Atmosphere and Ocean De‐Aliasing Level‐1B (AOD1B) product provides a priori information about temporal variations in the Earth's gravity field induced by non‐tidal circulation processes in atmosphere and ocean. It is ... -
Quantifying the Central European Droughts in 2018 and 2019 With GRACE Follow-On
(Geophysical Research Letters, 2020)The GRACE-FO satellites launched in May 2018 are able to quantify the water mass deficit in Central Europe during the two consecutive summer droughts of 2018 and 2019. Relative to the long-term climatology, the water mass ... -
Satellite Gravimetry: A Review of Its Realization
(Surveys in Geophysics, 2021-10-07)Since Kepler, Newton and Huygens in the seventeenth century, geodesy has been concerned with determining the figure, orientation and gravitational field of the Earth. With the beginning of the space age in 1957, a new ...
