Advances in GNSS-R altimetry

2017 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2017
Since the nadir 1-second altimetry precision was first estimated to be of 56 cm when the PARIS concept was developed back in 1993 (it was assumed the interferometric processing of GPS P-code signals and a 4×4 m×m receiving antenna at 700 km orbital altitude) [1], many detailed analyses and experiments have been conducted leading to far more optimistic ...

Meridional Dipole in Eddy Activity Along Peruvian Coast During Eastern Pacific El Niño Events

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Mesoscale oceanic eddies (O $O$(100)km) play a key role in regulating climate by affecting the transport of heat and water mass properties. However, most climate models struggle to simulate these eddies due to coarse horizontal resolution. Using a 120‐year ultra‐high‐resolution simulation with 1/10° ${}^{\circ}$ horizontal ocean resolution ...

Toward Comprehensive Understanding of Air‐Sea Interactions Under Tropical Cyclones: On the Importance of High Resolution and Multi‐Modal Observations

Geophysical Research Letters
The three‐dimensional structure of the Tropical Cyclone's baroclinic wake is synthesized as an averaged baroclinic‐dominant response of the upper ocean.

Eddy Kinetic Energy Contribution to Total Ocean Kinetic Energy From Multi‐Satellite Altimetry

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Ocean mesoscale structures play a central role in transporting oceanic properties, accounting for a significant fraction of ocean's total kinetic energy (KE). Using 23 years of a novel multisatellite altimetric estimate, we assess the contribution of eddy kinetic energy (EKE), mean kinetic energy (MKE) and cross terms to the temporal mean and ...

On Small Satellites for Oceanography: A Survey [PDF]

, 2015
The recent explosive growth of small satellite operations driven primarily from an academic or pedagogical need, has demonstrated the viability of commercial-off-the-shelf technologies in space. They have also leveraged and shown the need for development

Blocked Coastal Propagation Inhibits Model Representation of Southeast United States Coastal Sea Level Variability

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Previous studies indicate that climate models misrepresent southeast United States coastal sea level variability but do not propose a definitive mechanistic explanation. Here, by isolating a mode of variability responsible for the majority of observed nonseasonal United States East Coast (USEC) sea level variance and comparing its ...

Evaluation and Validation of CryoSat-2-Derived Water Levels Using In Situ Lake Data from China

Remote Sensing, 2019
CryoSat-2 altimetry has become a valuable tool for monitoring the water level of lakes. In this study, a concentrated probability density function (PDF) method was proposed for preprocessing CryoSat-2 Geophysical Data Record (GDR) data.

Projected Changes of Mesoscale Eddy Activity in Subantarctic Mode Water Formation Regions

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Subantarctic Mode Water (SAMW) plays a vital role in the uptake of heat and carbon, thereby regulating global climate. Mesoscale eddies affect mode‐water subduction and transport in the Southern Ocean. However, it remains unclear how SAMW‐related eddy activity will evolve under anthropogenic warming, because most state‐of‐the‐art climate ...

Post‐Hiatus Enhancement of ENSO Forecast Skill via Salinity‐Mediated Indo‐Pacific Inter‐Basin Coupling

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract The El Niño–Southern Oscillation (ENSO) predictability has notably declined since the 1998–2013 global warming hiatus, challenging conventional sea surface temperature (SST)‐based forecast models. We identify sea surface salinity (SSS) as a critical yet underappreciated driver for restoring ENSO forecast skill post‐hiatus.

Rain and ice flagging of Envisat altimeter and MWR data [PDF]

, 2004
Altimetry range, wave height, and wind speed measurements are often corrupted by two effects over the ocean: rain and sea-ice. Radiometer measurements, which provide the altimetric wet troposphere correction, are similarly corrupted by the presence of ...
