WMS GeoMet-Weather provides public access to the Meteorological Service of Canada (MSC) and Environment and Climate Change Canada (ECCC) data via interoperable web services and application programming interfaces (API). Through open standards, users can freely and quickly access thousands of real-time and archived weather, climate and water datasets and products and integrate them in their domain-specific applications and decision support systems. Users can build mobile apps, create interactive web maps, and display and animate MSC data in desktop software. MSC GeoMet also enables on demand raw data clipping and reprojection, on demand format conversion and custom visualization.

It covers the entire Arctic basin with a horizontal grid resolution of approximately 3 km. The system CAPS is driven by ECCC's Global Deterministic Prediction System (GDPS), which provides initial and lateral boundary conditions for atmospheric fields. Initial hydrometeorological fields are recycled from the 12-hour forecast of the previous CAPS integration. In addition, the GDPS is used to force the ocean-ice model outside the coupled regions. Initial conditions for ocean-ice fields are taken from the Regional Ocean-Ice Prediction System (RIOPS). Ocean boundary conditions in the North Atlantic and North Pacific come from the GDPS. The system CAPS runs twice a day and is initialized at 00 and 12 UTC, respectively, with a 48-hour integration.
