TL;DR: The polar regions have been attracting more and more attention in recent years, fueled by the perceptible impacts of anthropogenic climate change as mentioned in this paper, and it is argued that environmental prediction systems for the polar regions are less developed than elsewhere.

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.
Journal ArticleDOI
Sea ice forecast verification in the Canadian Global Ice Ocean Prediction System
Gregory C. Smith,François Roy,Mateusz Reszka,Dorina Surcel Colan,Zhongjie He,Daniel Deacu,Jean-Marc Bélanger,Sergey Skachko,Sergey Skachko,Yimin Liu,Frédéric Dupont,Jean-François Lemieux,Christiane Beaudoin,Benoît Tranchant,Marie Drevillon,Gilles Garric,Charles-Emmanuel Testut,Jean-Michel Lellouche,Pierre Pellerin,Harold Ritchie,Youyu Lu,Fraser Davidson,Mark Buehner,Alain Caya,Manon Lajoie +24 more
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
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).
