High Arctic Weather Stations

High Arctic Weather Stations, managed by the Monitoring and Science Division, Prairie and Northern Region of Environment Canada, began as the Joint Arctic Weather Stations. The plan for a network of Arctic weather bases was approved by the US on 12 February 1946, and on 28 January 1947 Cabinet formally agreed to participate. Between 1947 and 1950, five sites were selected and built jointly by Canada and the US (at Eureka, Isachsen, Mould Bay, Resolute and Alert) to provide the data required for the understanding and prediction of meteorological phenomena on a hemispheric scale and, 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.
