Intra‐Tessera Plains: Implications of Their Radar Properties for Surface Processes on Venus

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 9, September 2026.
Abstract Intra‐tessera plains are radar‐dark plains deposits that occur within tesserae. Their emplacement mechanism(s) and composition are poorly constrained, though they are hypothesized to be basaltic lava flows. Here, we map intra‐tessera plains within 16 different tesserae spanning various latitudes and elevations.

Nanosats for Radar Altimetry [PDF]

open access: yes, 2015
Radar altimeters such as TOPEX/Poseidon and Jason-2 measure the sea surface height as well as wave height and wind speed, providing key information about the ocean. The U.S.

Polygon‐Based Spectral Reflectance Sampling for Real‐Time River Discharge Estimation

open access: yesWater Resources Research, Volume 62, Issue 9, September 2026.
Abstract River discharge estimation (RDE) methods are traditionally prone to high costs, vulnerability to extreme events, and are constrained by real‐time data availability. Current remote sensing‐based RDE approaches mainly extract basic river features such as width and water surface elevation, but rarely exploit the full spectral information from ...

Envisat RA-2 Individual Echoes: A Unique Dataset for a Better Understanding of Inland Water Altimetry Potentialities

open access: yesRemote Sensing, 2017
The exploitation of synthetic aperture properties in nadir-looking radars is opening new scenarios in the framework of satellite radar altimetry. Both recent and upcoming missions including Cryosat-2, Sentinel-3, Sentinel-6 and SWOT take benefit from the

Validation of Copernicus Sea Level Altimetry Products in the Baltic Sea and Estonian Lakes

open access: yesRemote Sensing, 2020
Multi-mission satellite altimetry (e.g., ERS, Envisat, TOPEX/Poseidon, Jason) data have enabled a synoptic-scale view of ocean variations in past decades.

Global Estimate of Reservoir Hydropower Storage Potential Based on SWOT Observations

open access: yesEarth's Future, Volume 14, Issue 9, September 2026.
Abstract Hydropower is pivotal to the global transition toward carbon‐neutral energy, yet its actual potential remains constrained by uncertainties. Global assessments have traditionally relied on static metrics, such as dam height, which obscure the dynamic water fluctuations that govern operational reliability.

Observing and Modelling the HighWater Level from Satellite Radar Altimetry During Tropical Cyclones

open access: yes, 2015
This paper investigates the capability of observing tropical cyclones using satellite radar altimetry. Two representative cyclones Yasi (February 2011) and Larry (March 2006) in the northeast Australian coastal area are selected based also on available ...

Understanding uncertainties in the satellite altimeter measurement of coastal sea level: insights from a round-robin analysis [PDF]

open access: yesOcean Science
The satellite radar altimetry record of sea level has now surpassed 30 years in length. These observations have greatly improved our knowledge of the open ocean and are now an essential component of many operational marine systems and climate studies ...

Sea‐Level Change in Hong Kong From Tide Gauges, GNSS, and Satellite Altimetry

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.
Abstract As a densely populated, highly urbanized coastal city, Hong Kong is particularly vulnerable to sea‐level rise, which amplifies flood risk and threatens coastal infrastructure, economies, and ecosystems. We combine observations from tide gauges, conventional gridded satellite altimetry, coastal‐retracked altimetry, and Global Navigation ...

A New Global Hypsometric Data Set Derived From Satellite and Geometric Methods for Reservoir Storage Estimation

open access: yesWater Resources Research, Volume 62, Issue 9, September 2026.
Abstract Reservoir hypsometric relationships are crucial in determining water storage changes and modeling hydrological processes. Previous studies have demonstrated that uncertainties in reservoir surface area observations are a primary source of error in satellite‐derived storage estimates.
