Regional Deterministic Prediction System (RDPS)

The Regional Deterministic Prediction System (RDPS) carries out physics calculations to arrive at deterministic predictions of atmospheric elements from the current day out to 48 hours into the future at a 10.0 km grid (1/11 deg) spatial resolution. The data for mean temperature covers North America and is provided by the Meterological Service of Canada (MSC), a part of Environment and Climate Change Canada (ECCC). The MSC provides weather forecasts and warnings 24 hours a day, 365 days a year. MSC also provides federal department, agencies and other levels of government with information to support emergency preparedness and response to events such as storms, floods, wildfires and other weather-related emergencies. You can find additional information here and also on the climate org data page.
