Data Resources

Streamflow Data

• Water Survey of Canada
  Historical and real-time water level and streamflow data. Upstream basin polygons here

Meteorological Data (measured)

• MSC Historical Climate Data
  Historical hourly and daily gauge and radar meteorological data (web download month-by-month- for hourly data or year-by-year for daily data).
  • For downloading in bulk, try using the MSCr R package
  • For visualization of data in space and time, try Green Kenue or the
    Environment Canada Data Explorer
• ECCC Adjusted Daily Rainfall/Snowfall data (AdjDlyRS)
  Historical daily data corrected for SWE, gauge undercatch, and trace precipitation. Corrects historical underestimation of total precipitation on the Canadian Open Data Portal.
• Alberta Climate Information Service
• Provincial data sources in Alberta

Meteorological Data (simulated/downscaled)

• Canadian Precipitation Analysis (CaPa)
  Model-interpolated climate data generated from RDPS combined with gauge and radar data
• Canadian Meteorological Centre’s Numerical Weather Prediction (NWP) models
  Regional (RDPS), Global (GDPS), North American Ensemble (NAEFS) and seasonal forecasts in GRIB format.
• CaSPAr – Canadian Surface Prediction Archive data portal
  Historical ECCC regional climate prediction archives, available in NetCDF format
• ClimateNA_MAP
  North America-wide downscaled GCM climate data; monthly estimated variables from 1901-2010.
• PCIC Downscaled GCMS
  Canada-wide downscaled GCM climate data from the Pacific Climate Impacts Consortium (PCIC). Daily recip and min/max temperature in NetCDF or ASCII format for multiple scenarios.

Terrain Data

• Canadian Digital Elevation Model (CDEM) [preferred over CDED data]
  Canadian national elevation data product
• Canada Digital Elevation Data (CDED)
  Canadian national elevation data product
• Arctic DEM
  High resolution (5-m or better) digital elevation model data north of 60 latitude
• HydroSHEDS
  Global hydrologically-conditioned digital elevation models south of 60 latitude at 3 arc-second resolution.

Provincial Data and Data Tools

• Ontario Integrated Hydrology Data
  Harmonized Ontario Hydro Network-National Hydro Network stream and water body vector coverage with hydrologically corrected DEM and flow direction raster data for the province of Ontario.
• Ontario Flow Assessment Tool (OFAT)”
  Online map-based tool which creates watersheds, calculates watershed characteristics, executes simple hydrology models and reports water flow statistics.

Other Datasets

• CANOPEX – Canadian hydrometeorological watershed database
  Canada-wide database of 698 natural watersheds with 20+ years of record (streamflow and met data) for model intercomparison and assessment
