Water Resources Research, Volume 62, Issue 2, February 2026.Abstract Reservoirs play a crucial role in global water resource management. Monitoring reservoir hydrologic dynamics is critical for assessing climate variability and anthropogenic regulation. However, traditional satellite altimetry faces multiple challenges hindering high frequency and accuracy water level monitoring.

AGM2015: Antineutrino Global Map 2015
, 2015 Every second greater than $10^{25}$ antineutrinos radiate to space from Earth, shining like a faint antineutrino star. Underground antineutrino detectors have revealed the rapidly decaying fission products inside nuclear reactors, verified the long-lived

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 ...

Evolution of geoids in recent years and its impact on oceanography
Scientia Marina, 2014 Mean surface geostrophic ocean currents may be calculated from the Mean Dynamic Topography (MDT), estimated as the difference between a mean sea surface height (MSS) calculated from radar altimeters and a reference geoid height.

Deep Sources of Recent Volcanism in Armenia Inferred From Ambient Noise Tomography
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.Abstract We perform Rayleigh wave ambient noise tomography to investigate crustal seismic velocity structure and sources of volcanism in Armenia. Armenia, a key part of the tectonically and volcanically active Caucasus‐Anatolia region, is actively being deformed by the ongoing Arabian‐Eurasian continental collision.
