Through agreements with Environment Canada, ATS staff carry out aerological observations of the upper atmosphere. These aerological observations are completed at specified times everyday of the year and transmit the data to Environment Canada who will use this information in forecasting weather.

ATS provides aviation weather and communications services at Community Aerodrome Radio Stations, located at airports across Canada’s Arctic. These remote stations are equipped with meteorological instruments for monitoring and recording aviation surface weather and communications equipment for providing critical operational information to pilots. ATS operational staff provide a variety of services including aerodrome information services, vehicle information services and emergency services.

Contract Weather Offices provide aviation weather services at airports across southern Canada. Equipped with meteorological instruments for monitoring, recording and transmitting aviation surface weather, these observers provide the bulk of weather information for distribution across the country. ATS operates numerous CWOs including International Airports in Vancouver, Ottawa, Toronto, and Moncton.
