There are several aviation weather sites that provide raw data such as METARs and TAFs, and predictions of everything from icing, turbulence, cloud cover, severe weather, and forecast winds along a route. The Aviation Weather page includes sites from both Canada and the U.S. Here are some favourite sites: |

Computer Models |
|
Several countries or groups of countries have developed regional, hemispheric or global models to predict atmospheric conditions into the future by as much as ten days in advance. Mathematical models of the atmosphere use observational data and complex equations to analyze and project the state of the atmosphere, usually in 12 hour sequences, into the future. From these projections, daily forecasts are made by weather services, both commercial and state-run, with increasingly accurate results.

Climate Sites |
|
Most countries archive large quantities of meteorological and climate data, and publish or provide access to data in various formats, often online. In addition to data, there are sites that discuss climate change. Two of the most important sites for data include the Canadian Climate Centre and the National Climate data Centre in the U.S. |
