Welcome to the High Impact Weather Research Data Portal

The Canadian Arctic Weather Science (CAWS) is a science project to advance the knowledge necessary to understand the Arctic weather, climate, and cryosphereic systems, to test innovative technologies in support to the design of a cost-effective observing system for the Canadian Arctic, to validate space-based observations and support integration of space with ground-based network data, and to enhance the performance of the Canadian weather prediction system over the Canadian Arctic region. This is a science project led by ECCC and is committed with experimental data products only; as such all instruments operate in research mode. Please select an HIWR site from the list above to view near-real time data and obtain further information (instrument data descriptions). Below are some photos of the CAWS sites, including photos of other sites managed by the High Impact Weather Research (HIWR) Section.
