Influence of Nonseasonal River Discharge on Sea Surface Salinity and Height

open access: yesJournal 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

open access: yesEnvironmental 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

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

open access: yesCity 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

open access: yesRemote 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.

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

open access: yesThe 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.

Shipborne GNSS acquisition of sea surface heights in the Baltic Sea

open access: yesJournal of Geodetic Science, 2022
Abstract For determining precise sea surface heights, six marine GNSS (global navigation satellite system) survey campaigns were performed in the eastern Baltic Sea in 2021. Four GNSS antennas were installed on the vessel, the coordinates of which were computed relative to GNSS–CORS (continuously operating reference stations).
