Abstract Quantifying decadal‐scale erosion rates in tectonically active regions is essential for assessing landscape hazards and constraining sediment budgets. A key question in Earth surface processes is how contemporary erosion measurements influenced by recent climatic extremes relate to long‐term geological rates.

Potentialities and Limits of ICESAT-2 Observation for Atmospheric Aerosol Investigation
ICESat-2(Ice, Cloud, and land Elevation Satellite-2), slated for launch in 2017, will continue the important observations of ice-sheet elevation change, sea-ice freeboard, and vegetation canopy height begun by ICESat in 2003.

Backwater Effects From River Ice Jams Observed With SWOT Pixel Cloud Data
Abstract This study examines the backwater effects from ice jams in Arctic rivers using the Surface Water and Ocean Topography (SWOT) satellite. Ice jams occur when chunks of ice accumulate and obstruct the river flow, causing rapid water level rises and flooding.

Abstract The 6 June 2023 failure of the Kakhovka Dam generated a catastrophic outburst flood, leading to loss of life and infrastructure damage. During the flood, daily measurements of water surface elevation were collected by the SWOT satellite, providing the first direct, high‐resolution 2D measurements of a large outburst flood.

ICESat‐derived inland water surface spot heights [PDF]
AbstractAccurate measurement of water surface height is key to many fields in hydrology and limnology. Satellite radar and laser altimetry have been shown to be useful means of obtaining such data where no ground gauging stations exist, and the accuracy of different satellite instruments is now reasonably well understood.

Abstract Surface meltwater impacts Greenland Ice Sheet mass balance indirectly by reducing albedo and promoting hydrofracture. However, fully understanding both processes requires accurate mapping of small‐scale features such as ponds, channels, and moulins that govern meltwater formation and drainage. Here we investigate surface water dynamics at high

Runoff Capture by Sea Level Rise Alters the Area, Geometry, and Quantity of Coastal Catchments
Abstract Coastal catchments, which drain directly to the sea, mediate material fluxes across the land‐sea interface and support species diversity and economic activity in coastal zones. Here, we explore the evolution of coastal catchment divides at the local to global scale from 2000 to 2120 under multiple SLR scenarios using state‐of‐the‐art digital ...

Assessment of SWOT for Monitoring Ice‐Marginal Lake Water Levels in Greenland
Abstract The Surface Water and Ocean Topography (SWOT) satellite mission provides a powerful data set for monitoring global surface water resources. However, its performance for monitoring ice‐marginal lakes in Greenland remains unknown. Due to the scarcity of in situ measurements, this study evaluated the reliability of ice‐marginal lake elevations ...

AbstractLakes provide important water resources and many essential ecosystem services. Some of Earth's largest lakes recently reached record‐low levels, suggesting increasing threats from climate change and anthropogenic activities. Yet, continuous monitoring of lake levels is challenging at a global scale due to the sparse in situ gauging network and ...
