Subset of Data from the High Resolution Deterministic Prediction System (HRDPS)

Extract of the Meteorological Service of Canada Datamart: The High Resolution Deterministic Prediction System (HRDPS) carries out physics calculations to arrive at deterministic predictions of atmospheric elements from the current day out to 48 hours into the future. Atmospheric elements include temperature, precipitation, cloud cover, wind speed and direction, humidity and others. This product contains raw numerical results of these calculations. Geographical coverage of the system is most of Canada. Data is available over specific areas in the MSC Datamart and the whole coverage is available in the MSC GeoMet web services. Data is available at a horizontal resolution of about 2.5 km up to 31 vertical levels. Predictions are performed up to four times a day.

The subset of data availables on the SLGO catalogue provides the wind direction, wind speed and gust wind speed at 10m, as well as the air temperature at 2m. The dataset provide hourly data for the last three days and include 48-hours forecasts derived from the latest model run. Spatially, the SLGO subset covers the Québec and Ontario provinces (Canada), the Hudson Bay, and a localized portion of the Northwest Atlantic.

An interactive visualization of this dataset is available via the SLGO's Nautilo app
