The Hydrometeorological Sandbox - École de technologie supérieure (HYSETS) is a rich, general and large-scale database for hydrological modelling covering 14425 watersheds in North America. The database includes data covering the period 1950-2018 depending on the type and source of data:
- Watershed properties including boundaries, area, elevation slope, land use, soil properties and other physiographic information;
- Hydrometric gauging station discharge time-series;
- Maximum and minimum daily air temperatures and precipitation from weather gauges, NRCan and Livneh gridded interpolated products, SCDNA infilled-station data and ERA5 / ERA5-Land reanalyses;
- SNODAS and ERA5-Land snow water equivalent;
- Other diagnostic variables;
- Monthly agregation of meteorological variables;
- Elevation band data for each catchment in 100m increments.
All data has been processed and averaged at the watershed scale, and provides a solid basis for hydrological modelling, climate change impact studies, model calibration assessment, regionalization method evaluation and essentially any study requiring access to large amounts of spatiotemporally varied hydrometeorological data.
