Observation‐Driven Forecast of Global Terrestrial Water Storage and Evaluation for 2010–2024

Water Resources Research, Volume 62, Issue 2, February 2026.
Abstract Since 2002, the Gravity Recovery and Climate Experiment (GRACE) and GRACE Follow‐On (GRACE/‐FO) satellite missions have provided unprecedented measurements of terrestrial water storage changes (TWSC). These data are essential for monitoring the global water cycle, supporting drought and flood risk management, and informing water‐related ...

Satellite Data Trace Seasonal Freshwater Dispersion in Hudson and James Bays

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Freshwater dispersal controls stratification, circulation, and biogeochemical processes in Hudson and James Bay (HJB); however, limited field observations hinder understanding of how different freshwater types drive change. This study uses Aqua‐Moderate Resolution Imaging Spectroradiometer and Soil Moisture and Ocean Salinity‐Microwave Imaging

Satellite altimetry [PDF]

Since altimetry data are not really old enough to use the term data archaeology, Mr. Cheney referred to the stewardship of these data. He noted that it is very important to document the basis for an altimetry data set as the algorithms and corrections ...

Evaluating SWOT in the Coastal Zone: Comparisons With Tide Gauge and Airborne LiDAR in the Bristol Channel and Severn Estuary, UK

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Traditional nadir altimeters struggle with coastal water surface elevation (WSE) measurement and fine‐scale river‐estuary interactions, due to land‐water signal interference and their wide inter‐track spacing. The wide‐swath Surface Water and Ocean Topography (SWOT) mission, using a new Ka‐band radar interferometer, aims to address these ...

Dynamic Boundaries of Antarctic Active Subglacial Lakes Reveal Underestimated Water Volume Change and Overestimated Lakebed Active Area

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract This study revisited 158 documented active subglacial lakes across Antarctica, applying a height‐change anomaly delineation algorithm to CryoSat‐2 and ICESat‐2 satellite altimetry data to assemble a 14.75‐year (2010.5–2025.25) time series of active subglacial lake dynamics.

Wide‐Swath Satellite Altimetry Data Improves Modeled Mesoscale and Submesoscale Dynamics in a Western Boundary Current

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Ocean state estimates that represent mesoscale and submesoscale dynamics are crucial for climate research and ocean forecasting. Accurate submesoscale representation in ocean models is a current challenge due to rapidly evolving flow and lack of observations at suitable scales.

Strengthening of Labrador Sea Overturning Linked to Subsurface Freshening Over Recent Decades

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract The Labrador Sea is a key formation site for dense waters that contribute to the lower limb of the Atlantic meridional overturning circulation (AMOC). Recent observations have revealed a distinctly weak overturning in this basin, attributed to compensating effects of temperature and salinity anomalies on density.
