Sea Surface Height Measurements Based on Multi-Antenna GNSS Buoys [PDF]

Sensors
Sea level monitoring is an essential foundational project for studying global climate change and the rise in sea levels. Satellite radar altimeters, which can sometimes provide inaccurate sea surface height data near the coast, are affected by both the ...

Arctic sea surface height maps from multi-altimeter combination [PDF]

Earth System Science Data, 2021
We present a new Arctic sea level anomaly dataset based on the combination of three altimeter missions using an optimal interpolation scheme. Measurements from SARAL/AltiKa, CryoSat-2 and Sentinel-3A are blended together, providing an unprecedented ...

Lasting impact of winds on Arctic sea ice through the ocean's memory [PDF]

The Cryosphere, 2021
In this paper we studied the impact of winds on Arctic sea ice through the ocean's memory by using numerical simulations. We found that the changes in halosteric height induced by wind perturbations can significantly affect the Arctic sea ice drift ...

Influence of Nonseasonal River Discharge on Sea Surface Salinity and Height

Journal of Advances in Modeling Earth Systems, 2022
River discharge influences ocean dynamics and biogeochemistry. Due to the lack of a systematic, up‐to‐date global measurement network for river discharge, global ocean models typically use seasonal discharge climatology as forcing.

Sea surface height super-resolution using high-resolution sea surface temperature with a subpixel convolutional residual network

Environmental Data Science, 2022
The oceans have a very important role in climate regulation due to their massive heat storage capacity. Thus, for the past decades, oceans have been observed by satellites to better understand their dynamics. Satellites retrieve several data with various

Refining the sea surface identification approach for determining freeboards in the ICESat-2 sea ice products [PDF]

The Cryosphere, 2021
In Release 001 and 002 of the ICESat-2 sea ice products, candidate height segments used to estimate the reference sea surface height for freeboard calculations included two surface types: specular and smooth dark leads.

Deep learning of sea-level variability and flood for coastal city resilience

City and Environment Interactions, 2023
Due to climate change, it is important to study the relationship between floods and sea-level rise in coastal city resilience. In this research sea surface temperature (SST) from MODIS, wind speed, precipitation, and sea-level rise from satellite ...

Oceanic Eddy Detection and Analysis from Satellite-Derived SSH and SST Fields in the Kuroshio Extension

Remote Sensing, 2022
Vigorous mesoscale eddies are broadly distributed in the Kuroshio Extension and can generally be identified from sea surface height (SSH) and sea surface temperature (SST) fields.

Reconstruction of Surface Kinematics From Sea Surface Height Using Neural Networks

Journal of Advances in Modeling Earth Systems, 2023
The Surface Water and Ocean Topography (SWOT) satellite is expected to observe sea surface height (SSH) down to scales approaching ∼15 km, revealing submesoscale patterns that have never before been observed on global scales. Features at these soon‐to‐be‐
