Data and Products of the Global Deterministic Prediction System
The Global Deterministic Prediction System (GDPS) performs physical calculations to produce deterministic forecasts of atmospheric elements from the present day to 10 days in the future. Elements of the atmosphere include temperature, precipitation, cloud cover, wind speed and direction, and humidity. This product contains the raw numerical results of these calculations. The geographical coverage is global. The horizontal spatial resolution of the data is 15 km. Data is available for 33 vertical levels. The forecasts are carried out twice a day.
How to access the data
- Data available via the GeoMet-Weather geospatial web services
- GRIB2 data available on the MSC Datamart
- NetCDF global ice analysis on the MSC Datamart
An overview and examples to access and use the Meteorological Service of Canada's open data is available. Example of a web map configured to display the
