Ouranos provides access to weather forecasts from multiple Numerical Weather Prediction (NWP). These models are developed and maintained by leading meteorological agencies worldwide and differ in terms of geographical coverage, spatial resolution, update frequency, and forecast horizon.
Selecting the appropriate model depends on the region of interest and the required forecast accuracy.

The Integrated Forecasting System (IFS) is one of the world's leading global weather prediction models. It is widely recognized for its accuracy in medium-range forecasting and is commonly used as a benchmark for weather prediction.
The Artificial Intelligence Forecasting System (AIFS) is ECMWF's AI-driven forecasting model. It complements traditional numerical weather prediction approaches by leveraging machine learning techniques.
The Global Forecast System (GFS) is NOAA's primary global forecasting model. It offers worldwide coverage and frequent updates, making it suitable for operational weather monitoring.
The ICON model family, developed by the German Weather Service (DWD), provides both global and regional forecasts. High-resolution variants such as ICON-EU and ICON-D2 offer improved representation of local weather phenomena.
AROME is Météo-France's high-resolution forecasting model. Its fine spatial resolution enables detailed prediction of localized events, including thunderstorms, fog, and intense precipitation.
ARPEGE is Météo-France's global forecasting system. It combines global coverage with increased resolution over Europe and France.
