Schematic view of HYSETS database. 14425 North American (NA) watersheds are included in the database. This NA database includes data over the 1950–2018 period: (1) daily precipitation and minimum and maximum temperature products from 7 data sources; (2) hydrometric gauging station discharge time-series from one data source per country (Canada, Contiguous U.S., Mexico); (3) SNODAS and ERA5-Land snow water equivalent; and (5) watershed properties from PAVICS-Hydro (area, elevation slope, land use, soil properties and other physiographic information).
