A Study on the Assimilation of Swath Altimetry Data into a Global Hydrodynamic Model

A Study on the Assimilation of Swath Altimetry Data into a Global Hydrodynamic Model
Limitations of the in-situ observations and the hydrodynamic modeling make it difficult to assess the water resources accurately.Recent advances in satellite technology have enabled estimation hydrodynamic characteristics from remote sensing data. Data assimilation methods were increasingly used to correct hydrodynamic model forecasts with the use of ...

Multi-Source Satellite Altimetry for Monitoring Storm Wave Footprints in the English Channel’s Coastal Areas

Remote Sensing
Climate wave data, derived from significant wave height (SWH) altimetry, provide accurate information towards nearshore and coastal areas. Their use is crucial to enhance our capabilities of observing, understanding, and forecasting storm waves, even in ...

Block-Circulant Approximation of the Precision Matrix for Assimilating SWOT Altimetry Data

Remote Sensing
The recently deployed Surface Water and Ocean Topography (SWOT) mission for the first time has observed the ocean surface at a spatial resolution of 1 km, thus giving an opportunity to directly monitor submesoscale sea surface height (SSH) variations ...

Wide‐Swath Satellite Altimetry Data Improves Modeled Mesoscale and Submesoscale Dynamics in a Western Boundary Current

Geophysical Research Letters
Ocean state estimates that represent mesoscale and submesoscale dynamics are crucial for climate research and ocean forecasting. Accurate submesoscale representation in ocean models is a current challenge due to rapidly evolving flow and lack of ...

Contribution of the wide-swath altimetry mission SWOT to improve large-scale hydrological modeling

, 2017
Scientific objective of this PhD work is to improve water fluxes estimation on the continental surfaces, at interanual and interseasonal scale (from few years to decennial time period). More specifically, it studies contribution of remotely-sensed measurements to improve hydrology model.

Wide-swath satellite altimetry reveals hotspots of small mesoscale eddies in the western Arctic Ocean

Communications Earth & Environment
Ocean eddies play crucial roles in climate and marine ecosystems. Still, small mesoscale eddies in the climate-sensitive and biologically unique Arctic Ocean remain poorly characterized and understood due to the coarse resolution of traditional gridded ...
