The Canadian Seasonal to Interannual Prediction System version 3 (CanSIPSv3), developed by Environment and Climate Change Canada, provides monthly and seasonal forecasts over the upcoming 12 months at a resolution of approximately 100 km x 100 km. CanSIPSv3 uses two coupled atmosphere-ocean-land climate models: CanESM5 and GEM5.2-NEMO. CanSIPSv3 forecasts are generated using an ensemble of 40 model simulations, 20 from each model. Probabilistic forecasts provide information about possible future climate conditions relative to the 1991-2020 reference period.
