Daymet (Thornton et al., 2020; 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). Daymet considère une journée comme une fenêtre de 24 heures en heure local.

GSMaP has multi-satellite global precipitation map under the Global Precipitation Measurement (GPM) Mission, by using Dual-frequency Precipitation Radar (DPR) onboard GPM core satellites, other GPM constellation satellites, and Geostationary satellites. GSMaP provides hourly precipitation estimates. A gauge-corrected precipitation estimate is also provided.
Note: Both datasets may contain negative values, which denotes missing in observation data or no retrieval was done in microwave retrieval algorithm. More information can be found in the related documentation https://sharaku.eorc.jaxa.jp/GSMaP/document/new/DataFormatDescription_NRT7.pdf.

IMERG V7
The Integrated Multi-satellitE Retrievals for GPM (IMERG) IMERG is a NASA product estimating global surface precipitation rates at a high resolution of 0.1° every half-hour beginning 2000. It is part of the joint NASA-JAXA Global Precipitation Measurement (GPM) mission, using the GPM Core Observatory satellite as the standard to combine precipitation observations from an international constellation of satellites using advanced techniques. IMERG can be used for global-scale applications as well as over regions with sparse or no reliable surface observations. The fine spatial and temporal resolution of IMERG data allows them to be accumulated to the scale of the application for increased skill. While IMERG strives for consistency and accuracy, satellite estimates of precipitation are expected to have lower skill over frozen surfaces, complex terrain, and coastal zones. As well, the changing GPM satellite constellation over time may introduce artifacts that affect studies focusing on multi-year changes.
**Please note that the precipitation in mm/hr in with the timestamp h:mm represent the accumulation for the period [h:mm, h:mm + 30m[**
