Data and Products of the Global Deterministic Prediction System
The Global Deterministic Prediction System (GDPS) is a coupled atmosphere (GEM), ocean and sea ice (NEMO-CICE) deterministic numerical weather prediction model. Forecasts are carried out twice a day for 10 days lead time. The geographical coverage is global on a native Yin-Yang grid at 15 km horizontal resolution. Data is available for 33 vertical levels and interpolated on a global latitude-longitude uniform grid with 0.2 degree horizontal resolution. Variables availability in number and time frequency is a function of forecast lead time.
Access
How to access the data
This data is available from the MSC GeoMet API / web services and on the MSC Datamart data server respectively:
- Data available via the GeoMet-Weather geospatial web services
- GRIB2 data available on the MSC Datamart
- GeoJSON statistically post-processed data on the MSC Datamart
- Experimental GRIB2 weather elements on the grid data available on the MSC testing data repository DD-Alpha
- 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 GDPS.DIAG_NW_PT1H layer served by MSC GeoMet:
