ICESAT-2 ALTIMETRY AS GEODETIC CONTROL [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020 Abstract. Digital elevation models (DEMs) are of fundamental importance for a large variety of scientific and commercial applications. Many geoscience studies require the most precise and current information about the Earth’s topography. Independent quality assessments of these DEMs are crucial to their appropriate use in land process studies, as ...

A Regional Intercomparison of Ice Sheet Mass Balance Estimates of the Northwest Greenland Ice Sheet
Journal of Geophysical Research: Earth Surface, Volume 131, Issue 10, October 2026.Abstract Changes in ice sheet mass manifest as changes in ice flow, ice thickness, and gravitational attraction. These parameters can be measured from space and used to track Greenland's contribution to sea level rise independently from each other. While an excellent level of agreement between these satellite techniques has been demonstrated at the ice

Alluvial ridge morphology on avulsing rivers
Sedimentology, Volume 73, Issue 6, Page 2311-2337, October 2026.ABSTRACT Alluvial ridges are built by preferential channel‐belt deposition and control river avulsions, yet a systematic analysis of their morphology has been missing. To address this gap, we analyse a globally distributed dataset of 8970 alluvial ridge flanks on 14 different rivers.

SWOT Observations Reveal Basin‐Scale Reservoir Operating Patterns
Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract The construction and operation of reservoirs have fundamentally modified the natural hydrograph globally. However, complex seasonal operating patterns remain opaque due to data scarcity, limiting the accuracy of hydrological modeling and water management.
