Contribution of future wide-swath altimetry missions to ocean analysis and forecasting [PDF]

Ocean Science, 2018
The impact of forthcoming wide-swath altimetry missions on the ocean analysis and forecasting system was investigated by means of OSSEs (observing system simulation experiments). These experiments were performed with a regional data assimilation system,

Contribution of a constellation of two wide-swath altimetry missions to global ocean analysis and forecasting [PDF]

Ocean Science, 2022
Swath altimetry is likely to revolutionize our ability to monitor and forecast ocean dynamics. To meet the requirements of the EU Copernicus Marine Service, a constellation of two wide-swath altimeters is envisioned for the long-term (post-2030 ...

SWATH- A new concept for the Safety and Security at Sea

Ciencia y tecnología de buques, 2015
SWATH means Small Waterplane Area Twin Hull and is guarantor for excellent sea keeping behaviour.The basis of this ship type was born in the 1960’s and 70’s when semi-submersible vessels were introduced to the offshore market. Naval architects developed these vessels further and it was used as navy test craft, pilot tender, yachts, passenger boats etc ...

HYDRODYNAMIC PERFORMANCES OF SMALL SIZE SWATH CRAFT

Brodogradnja, 2015
The good seakeeping characteristics of SWATH hull form are very interesting for small working craft and pleasure boats. Intrinsic limitations as the low values of weight per inch of immersion and transversal and longitudinal instability, can be ...

Extracting tidal variability of sea ice concentration from AMSR‐E passive microwave single‐swath data: a case study of the Ross Sea [PDF]

Geophysical Research Letters, 2013
AbstractThe periodic divergence of stress applied by ocean tidal currents to sea ice affects the time‐averaged ice concentration (Cice) and heat and freshwater fluxes at the ocean surface. We demonstrate that, at sufficiently high latitudes, tidal variability in Cice can be extracted from single‐swath data from the Advanced Microwave Scanning ...

Measurement of Wind Waves and Wave-Coherent Air Pressures on the Open Sea from a Moving SWATH Vessel

Journal of Atmospheric and Oceanic Technology, 2005
Abstract The design and implementation on a Small Waterline Area Twin Hull (SWATH) vessel of a complete system for measuring the directional distribution of wind waves and the concomitant fluctuations of air pressure and wind speed immediately above them are described.

Wind Speed Retrieval Algorithm Using Ku-Band Radar Onboard GPM Satellite

Remote Sensing, 2021
The algorithm to retrieve wind speed in a wide swath from the normalized radar cross section (NRCS) was developed for the data of Dual Frequency Precipitation Radar (DPR) operating in scanning mode installed onboard a Global Precipitation Measurement ...

The demand analysis of oceanic T-S-V 3D reconstruction on wide-swath SSH data features based on ROMS and 4DVAR

Oceanologia, 2020
Summary: Future wide-swath altimetry missions will provide high-resolution information about ocean surface elevation, and facilitate the characterization of meso- and sub-mesoscale ocean activities. In this study, the demand analysis of three-dimensional

Assimilation of satellite swaths versus daily means of sea ice concentration in a regional coupled ocean–sea ice model

The Cryosphere, 2023
Abstract. Operational forecasting systems routinely assimilate daily means of sea ice concentration (SIC) from microwave radiometers in order to improve the accuracy of the forecasts. However, the temporal and spatial averaging of the individual satellite swaths into daily means of SIC entails two main drawbacks: (i) the spatial resolution of the ...
