TL;DR: In this article, a multi-reanalysis ensemble is used to estimate the signal-to-noise ratio (SNR) of the ocean state and to estimate uncertainty levels.

TL;DR: The Global Ice Ocean Prediction System (GIOPS) as discussed by the authors is a multivariate ocean data assimilation system that combines satellite observations of sea-level anomaly and sea-surface temperature (SST) together with in situ observations of temperature and salinity.
Journal ArticleDOI

TL;DR: The results from the Ocean ReAnalyses Intercomparison Project (ORA-IP) are presented in this paper, with a focus on Arctic sea ice fields reconstructed by state-of-the-art global ocean reanalyses.
Journal ArticleDOI
A new atmospheric dataset for forcing ice–ocean models: Evaluation of reforecasts using the Canadian global deterministic prediction system
Gregory C. Smith,François Roy,Philip Mann,Frédéric Dupont,Bruce Brasnett,Jean-François Lemieux,Stéphane Laroche,Stéphane Bélair +7 more
TL;DR: In this paper, the authors introduce a relatively high-resolution alternative forcing dataset for ice-ocean models derived from the Canadian Meteorological Centre's (CMC) global deterministic prediction system (GDPS).
Journal ArticleDOI
A high-resolution ocean and sea-ice modelling system for the Arctic and North Atlantic oceans
Frédéric Dupont,S. Higginson,Romain Bourdallé-Badie,Youyu Lu,François Roy,Gregory C. Smith,Jean-François Lemieux,Gilles Garric,Fraser Davidson +8 more
TL;DR: In this paper, a high-resolution (1/12°) ice-ocean regional model is developed covering the North Atlantic and the Arctic oceans, and a series of hindcasts for the period 2003-2009 are carried out, forced at the surface by the Canadian GDPS reforecasts (Smith et al., 2014).
