Retrieval of Sea Level and Surface Loading Variations from Geodetic Observations and Model Simulations: an Integrated Approach
(2014-04-07)
The mass distribution in the system Earth changes dynamically over time. Time-variable mass transport mainly arises from the interplay between the terrestrial hydrological water cycle, the ocean and atmosphere, and the ...
Statistical Signal Decomposition Techniques for Analyzing Time-Variable Satellite Gravimetry Data
(2014-09-29)
The time-variable gravity fields from the Gravity Recovery and Climate Experiment (GRACE) satellite mission provide valuable information about total water storage variations on a global scale. This quantity is difficult ...
Methods for assimilating remotely-sensed water storage changes into hydrological models
(2016-10-17)
Understanding physical processes within the water cycle is a challenging issue that requires merging information from various disciplines. The Gravity Recovery And Climate Experiment (GRACE) mission provides a unique ...
Large-scale mass redistribution in the Earth system from synergistic use of Swarm data
(2022-01-26)
Long and consistent time series of large-scale mass redistribution in the Earth system are important in many scientific research areas. The dedicated Gravity Recovery And Climate Experiment (GRACE) and Gravity Recovery And ...
Consistently closing global and regional sea level budgets
(2022-11-17)
Nowadays, human-induced climate change is the major driver of global and regional sea level change threatening the well-being and livelihoods of hundreds of millions of people living close to the coast. Consequently, ...
