Plusieurs sources d’informations sont assimillées dans le cadre de la réanalyse ERA5 comme les observations de stations de surface, les observations satellitaires, les METAR, etc. Les données ont été téléchargés à partir du Climate Data Store de Copernicus (C3S, 2017). L'extension 1950-1978 est considérée comme étant préliminaire dû à un problème avec la vitesse des vents dans les cyclones tropicaux. L'utilisation de ces données pour l'étude des cyclones tropicaux n'est donc pas appropriée.

Observations
CaLDAS
CaLDAS (Canadian Land Data Assimilation System) est un ensemble de données à 0.0225° basé sur l’assimilation de données satellitaires et de surface. C’est un produit ensembliste avec 25 membres disponible à chaque 3 heures. L’épaisseur de neige est analysée, mais pas le SWE directement. Afin de créer, une valeur “analysée” de SWE, l’épaisseur de neige analysée a été multiplié par la densité de la neige simulée. Les données ont été téléchargés à partir de CaSPAr (Canadian Surface Prediction Archive) (Mai et al., 2019).

Daymet
Daymet (Thornton et al., 2016; Thornton et al., 1997) est un ensemble de données à 1 km sur une projection conique conforme de Lambert issu de l’interpolation de données de station. Les données sont disponibles une fois par jour. La valeur de SWE disponible dans daymet a été été calculée dans le cadre de l’algorithme de calcul de la radiation solaire quotidienne afin d’en réduire le biais et donc est une valeur estimée. La température moyenne quotidienne de l'air est calculée à partir de la température minimale et maximale pour chaque jour de la façon suivante : tavg=0.5*(tmax+tmin).

GlobSnow
Globsnow 3.0 (Luojus et al., 2020) est un ensemble de données à 25 km sur une projection azimutale équivalente de Lambert sur l’hémisphère nord issu de l’assimilation de données de stations ainsi que des données satellitaires. Les données sont disponibles une fois par mois (une version journalière est disponible également). Il faut faire attention de la façon dont ses données sont utilisées, car la présence de « flag » ayant des valeurs négatives y figurent. Ex : -1 pour l’eau et -2 pour les montagnes. L’interpolation sans prêter attention aux flags pourraient causer ces « flags » d’être « mélangées » avec des données environnantes. Une version avec correction du biais de février à mai est aussi disponible.

SNODAS
SNODAS (Barrett, 2003) est un ensemble de données à 0.0083° basé sur l’assimilation de données satellitaires et de surface. L’assimilation a lieu à chaque jour à 06:00 UTC. Seulement ce pas de temps est disponible et sauvegarder pour archivage. Les données ont été téléchargés à partir du site du National Operational Hydrologic Remote Sensing Center (NOHRSC, 2004). Les fichiers originaux SNODAS sont sur un format binaire int16. Ils doivent êtres géoréférencées sur une projection WGS84 avec GDAL.
