On the Use of Doppler Shift for Sea Surface Wind Retrieval From SAR
Alexis Mouche,Fabrice Collard,B. Chapron,Knut-Frode Dagestad,G. Guitton,Johnny A. Johannessen,V. Kerbaol,Morten W. Hansen +7 more
TL;DR: In this article, an empirical geophysical model function (CDOP) is derived, predicting Doppler shifts at both VV and HH polarization as function of wind speed, radar incidence angle, and wind direction with respect to radar look direction.
Journal ArticleDOI
Retrieval of Sea Surface Range Velocities From Envisat ASAR Doppler Centroid Measurements
Morten W. Hansen,Fabrice Collard,Knut-Frode Dagestad,Johnny A. Johannessen,P. Fabry,B. Chapron +5 more
TL;DR: The processing steps and error corrections needed to retrieve estimates of sea surface range Doppler velocities from Envisat Advanced Synthetic Aperture Radar Wide Swath Medium resolution image products are presented and retrieval accuracies based on examination of the corrected Dopplers shift measurements are assessed.
Journal ArticleDOI

Pandey +25 more
TL;DR: In this paper, the optical, near-infrared, and X-ray observations of the optical afterglow (OA) of the gamma-ray burst GRB 011211 were presented.
Journal ArticleDOI
A small-scale oceanic eddy off the coast of West Africa studied by multi-sensor satellite and surface drifter data
Werner Alpers,Peter Brandt,Alban Lazar,Dominique Dagorne,Bamol Ali Sow,Saliou Faye,Morten W. Hansen,Angelo Rubino,Pierre-Marie Poulain,Patrice Brehmer +9 more
TL;DR: In this article, a small-scale cyclonic eddy was generated at the headland of Cap-Vert off the coast of Senegal, West Africa, and then propagated westward into the open North Atlantic Ocean.
Journal ArticleDOI
Classification of sea ice types in Sentinel-1 synthetic aperture radar images
TL;DR: In this article, a new Sentinel-1 image-based sea ice classification algorithm using a machine learning-based model trained in a semi-automated manner is proposed to support daily ice charting.
