We provide a data set that illustrates how the amount of water that is stored in the subsurface as groundwater varies in time over the continents of the Earth. An important part of the data comes from satellites that track changes in water by its gravity effect. The data allow for assessing how groundwater as the most important freshwater resource for mankind and ecosystems is affected by climate variability, climate change and withdrawal by human activities.

GOCO2025s is a global gravity field model derived from satellite observations collected over a period of 23 years. By combining complementary measurement principles from different satellite missions, it provides a highly accurate representation of the Earth’s gravity field. This information is crucial for investigating the dynamics and ongoing changes of our planet.

Basal ice-shelf melting critically impacts Antarctic ice sheet evolution. Our testing of two melting schemes showed starkly diverging projections despite near-identical initial states, especially for West Antarctica. By 2100, the predicted sea-level contributions differed by 57%. Initial setup changes hidden sub-ice properties (e.g., friction, temperature), modifying ice flow. Accurately representing melt and refining setup are thus essential to reduce projections uncertainty.

This study provides a statistically traceable, uncertainty-aware assessment of global terrestrial and groundwater storage trends based on 21.5 years of GRACE/-FO observations using the Global Gravity-based Groundwater Product (G3P). By accounting for long-range memory and interannual variability, we isolate robust trends from climate variability and noise. The analysis refines continental budgets and identifies emerging groundwater gains alongside widespread persistent decline.

Sea level rise is a major consequence of climate change, affecting the well-being of humankind. We combined long-term tide gauge records and satellite data to create a new global sea level record from 1950 to 2022. Our results reveal how natural climate patterns, including El Niño, La Niña, and the Pacific Decadal Oscillation, influence rapid present-day sea level change. The data product enhances understanding of climate–sea level interactions.

The Gravity Recovery And Climate Experiment (GRACE) mission has greatly improved our understanding of changes in Earth's gravity field over time. A novel mass concentration (mascon) dataset, GCL-Mascon2024, was determined by leveraging the short-arc approach, advanced spatial constraints, a frequency-dependent noise processing strategy, and parameterization-integrating natural boundaries, aiming to enhance accuracy for monitoring mass transportation on Earth.

Short summary
Propagation of electromagnetic signals in Earth's neutral atmosphere inflicts errors in space geodetic observations. To model these errors accurately, it is necessary to use a signal tracing algorithm which is informed of the state of the atmosphere. We developed such an algorithm and tested it by processing Global Navigation Satellite System network observations. Our algorithm's main advantage is lossless utilization of atmospheric information provided by numerical weather prediction models.

Gravity aspects are applied to the well-known impact craters Popigai and Chicxulub. Findings about them from 2010 are confirmed and extended with better data and a more advanced method. Both craters are double or multiple craters. Both crater formations seem to be associated with impact-induced tectonics that triggered the development of impact grabens.

GRACE and GRACE-FO are unique observing systems to quantify mass changes at the Earth’s surface from space. Time series of these mass changes are of high value for various applications, e.g., in hydrology, glaciology, and oceanography. GravIS (Gravity Information Service) provides easy access to user-friendly, regularly updated mass anomaly products. The portal visualizes and describes these data, aiming to highlight their significance for understanding changes in the climate system.

This study recommends a framework for preparing and processing vertical land displacements derived from GPS positioning for future integration with Gravity Recovery and Climate Experiment (GRACE) and GRACE-Follow On (GRACE-FO) measurements. We derive GPS estimates that only reflect surface mass signals and evaluate them against GRACE (and GRACE-FO). We also quantify uncertainty of GPS vertical land displacement estimates using various uncertainty quantification methods.

Short summary
Production of satellite products relies on information from different centers. By coupling a weather model and an orbit determination solver we eliminate the dependence on one of the centers. The coupling has proven to be possible in the first stage, where no formatting has been applied to any of the models involved. This opens a window for further development and improvement to a coupling that has proven to be as good as the predecessor model.

Short summary
Although not the primary mission of the Swarm three-satellite constellation, the sensors on these satellites are accurate enough to measure the melting and accumulation of Earth’s ice reservoirs, precipitation cycles, floods, and droughts, amongst others. Swarm sees these changes well compared to the dedicated GRACE satellites at spatial scales of roughly 1500 km. Swarm confirms most GRACE observations, such as the large ice melting in Greenland and the wet and dry seasons in the Amazon.
Although not the primary mission of the Swarm three-satellite constellation, the sensors on...
