The plan for a network of Arctic weather stations was approved in 1946 and
several sites were selected and built jointly by Canada and the US to provide
the data required for the understanding and prediction of meteorological
phenomena on a hemispheric scale, more specifically, to improve weather
predictions for North America.
The meteorological data collected is also used by forecasting offices, airlines,
northern shipping, climatology studies and research.
Each station collects its upper-air data primarily from hydrogen-gas weather
balloons, which are launched every 12 hours with an attached radiosonde
instrument that transmits temperature, pressure and humidity.
Other scientific activities include seismic and magnetic recordings, air
quality measurements and aerosol monitoring, tidal gauge, and integrated
environmental monitoring related to hydrology, vegetation, wildlife and
soil movements.
The stations also act as sovereignty outposts.
