The Whitehorse enhanced meteorological site is located at Erik Nielsen Whitehorse International Airport (CYXY, 60°43N, 135°04W). This scientific observation site aims to provide a better understanding of the region’s weather conditions to help improve local weather forecasts across the Canadian Arctic and sub-Arctic. For instance, new radar technology is being tested at this site to assess its suitability for detecting and analyzing this region’s weather systems.
A companion site in Iqaluit NU (CYFB, 63°45N, 68°33W), in the eastern Canadian Arctic, has also been established. It is important to note that Iqaluit is located above the tree line, while Whitehorse is below, resulting in a significantly more humid atmosphere at Whitehorse suggesting different weather monitoring requirements.
The Whitehorse site includes an X-band radar, a Doppler lidar, ceilometers, radiation flux and precipitation sensors, and others. Data collection for a subset of instruments at Whitehorse began in January 2018.
