Free weather data service

We provide raw weather, water, climate and environmental data via the Meteorological Service of Canada (MSC) Datamart.

Through this service, you will find data such as:

• numerical weather and environmental prediction forecasts (several forecast hours available according to the models) for North America or the world offered in GRIB2 and NetCDF format
• probability forecasts derived using a technique called “ensemble forecasting”
• observed and forecast vertical temperature profiles
• official forecasts with hourly values in different formats (XML, CSV)
• weather warning data and products in the Common Alerting Protocol (CAP) format
• a variety of radar images, including precipitation accumulations
• hourly Canadian site observations in XML format
• varied national and international weather bulletins in text format
• air quality data
• wave model data
• trajectories data (hurricanes, storms)
• climate data

New data, information and formats are added as they become available.
