Gulf of St. Lawrence 5 km Physics Analysis and Forecast Updated Every 6 hrs
Satellite image showing ice and cloud cover over the Gulf of St. Lawrence in winter.
Overview:
The Regional Deterministic Prediction System Coupled over the Gulf of St. Lawrence (RDPS-CGSL) provides analyses and 48 hr forecasts of atmospheric, ice and ocean conditions over the Gulf of St. Lawrence every 6 hours. The atmospheric model uses a 10 km resolution grid while the ice-ocean model uses a 5 km resolution grid. RDPS-CGSL is initialized using atmospheric analyses from the 10 km resolution Regional Deterministic Prediction System together with ice and ocean analyses produced using a data assimilation system that combines model estimates with RADARSAT image analyses produced by the Canadian Ice Service.
Ice and ocean forecast and analysis products from RDPS-CGSL:
- sea surface height (m)
- water temperature (°C)
- water salinity (psu)
- currents (m/s)
- sea ice fraction (%)
- snow depth on sea ice (m)
- ice thickness (m)
- ice drift velocity (m/s)
- ice pressure (N/m)
