Satellite communications: weather networks tour

Environment Canada collects some of its weather information by satellite and redistributes it the same way, on a separate satellite system.  That's how we gather weather reports from remote locations.  Satellite systems also make it possible for people to get the weather information they need even if they don't have access to the Internet or--in some cases--to telephones.

Hourly weather observations are collected from over 700 weather stations (most of them automated) using equipment like that installed in our instrument compound. Weather data is also collected from marine buoys, from ships, from Upper Air stations, and from volunteer climate observers.  Weather reports can be transmitted by satellite, by computer, or by telephone depending on the type of report and the location.  This map shows where the weather stations are located.
