Daily Freshwater Discharge from 477 Eastern Canadian Rivers (1990-2100)

Fisheries and Oceans Canada provides neural network post-processed WRF-Hydro streamflow timeseries for 477 eastern Canadian river outlets. The dataset models daily freshwater discharge from 1990 to 2100 using four CMIP climate models under different emission scenarios. It is used to force eastern Canadian ocean models.

Use Cases

• Analyze long-term trends in freshwater discharge from 477 river outlets under SSP2 4.5 and SSP5 8.5 climate scenarios.
• Force regional ocean circulation models using the WRF-Hydro streamflow timeseries data for the eastern Canadian coast.
• Compare streamflow projections from different climate models like CCSM-4, HadGEM2, and MPI-ESM1.2-LR for the same river outlets.
• Study the spatial distribution of river discharge using the provided lat/lon, riverlat/lon, and oceanlat/lon coordinate sets.

Strengths

• Covers a 111-year time series from 1990 to 2100, enabling analysis of long-term climate impacts.
• Includes data for 477 distinct river outlets across eastern Canada, providing broad spatial coverage.
• Integrates outputs from four established CMIP climate models (CCSM-4, HadGEM2, MPI-ESM1.2-LR) under multiple emission scenarios.
• Data is post-processed with a neural network to refine the WRF-Hydro model outputs.

Limitations

• The data is a model projection, not observed measurements, and is subject to climate model uncertainties.
• Specific variable details, column counts, and sample sizes are not provided in the metadata.
• Use requires contacting the data custodian, which may delay or restrict access for some applications.
