Surface Weather Stations

Accurate and timely surface weather data is essential for understanding severe convective storms, especially in regions with complex and dynamic climates like Canada. In-situ weather observations  (those collected directly at the ground) provide critical real-time information that remote sensing tools like satellites and radars can not always capture. These observations allow us to measure temperature, precipitation, wind speed, humidity, and other meteorological variables at the earth's surface, improving our ability to detect severe convective storms.

The Northern Mesonet Project plays a vital role in centralizing and integrating these in-situ observations though the CSSL Weather Intelligence. With contributions from 40 external partners, the Northern Mesonet Project gathers data from over 3,300 surface weather stations across Canada, along with an additional 500 stations in the United States of America. This expansive network ensures that we can monitor localized weather conditions, identify trends, and improve forecasts. By combining data from government agencies, research institutions, and industry stakeholders, the Northern Mesonet Project offers an unparalleled source of weather information that is accessible to researchers, forecasters, and the general public alike.
