Ocean Surface Topography Altimetry by Large Baseline Cross-Interferometry from Satellite Formation

Remote Sensing, 2020
Imaging Radar Altimeter (IRA) is the current development tendency for ocean surface topography (OST) altimetry, which utilizes Synthetic Aperture Radar (SAR) and interferometry to improve the spatial resolution of OST to several kilometers or even better.

Remote Sensing Hydrology Revisited: Advances, Persistent Challenges, and a Science‐Driven Agenda for the Next Decade

Water Resources Research, Volume 62, Issue 9, September 2026.
Abstract In the WRR 50th Anniversary Special Collection, Lettenmaier et al. (2015, https://doi.org/10.1002/2015WR017616) provided a timely account of how satellite remote sensing evolved from a niche capability in hydrology into a mainstream driver of hydrologic discovery, as the community shifted from imagery toward validated Earth Observation (EO ...

Floods From Space: How Remote Sensing, AI, and Cloud Platforms Are Reshaping Disaster Risk Reduction

Journal of Flood Risk Management, Volume 19, Issue 3, September 2026.
ABSTRACT Flooding remains one of the most damaging climate‐related hazards globally, yet flood remote sensing has historically developed largely along sensor‐specific pathways. This review addresses the need for a systematic and decision‐oriented synthesis of how space‐borne remote sensing has evolved toward integrated flood monitoring and disaster ...

Using Drones for Large Mammal Monitoring

Mammal Review, Volume 56, Issue 3, September 2026.
Drones were used to obtain video data on animals and locations and distance from the midline was automatically determined by our pipeline so that the input for Distance sampling is generated. ABSTRACT Introduction The emergence of drones has profoundly transformed the field of large mammal monitoring, offering unprecedented capabilities for data ...

Satellite Altimetry Reveals an Eddy Train Along the Ross Sea Shelf Break

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Oceanic circulation along the Antarctic shelf break regulates heat and material exchanges between the continental shelf and the open ocean, playing a crucial role in ice shelf melting and global overturning circulation. However, the circulation remains poorly understood due to limited observations.

Detecting an Ocean Inside Callisto With Geodetic Measurements From Europa Clipper and Juice

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Determining whether Callisto hosts a subsurface ocean, and the implications for material and energy transport through its hydrosphere, is of high interest to NASA's Europa Clipper and ESA's Juice missions. A recent reanalysis of Galileo magnetometer data strengthens the ocean hypothesis, but definitive confirmation awaits new measurements.

First Assessment of ICESat‐2 Summer Sea Ice Freeboard With Airborne Validation

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract ICESat‐2 has demonstrated solid performance in retrieving sea ice freeboard during winter, when sea ice surface types are well‐defined and leads provide reliable sea surface height references. Summer retrievals are challenging because melt ponds are not explicitly distinguished in the ATL07 surface classification and may be identified as ice ...

Modeling Envisat RA-2 waveforms in the coastal zone: case-study of calm water contamination [PDF]

, 2010
Radar altimeters have so far had limited use in the coastal zone, the area with most societal impact. This is due to both lack of, or insufficient accuracy in the necessary corrections, and more complicated altimeter signals. This paper examines waveform

Multi-Satellite Altimeter Validation along the French Atlantic Coast in the Southern Bay of Biscay from ERS-2 to SARAL

Remote Sensing, 2018
Monitoring changes in coastal sea levels is necessary given the impacts of climate change. Information on the sea level and its changes are important parameters in connection to climate change processes.
