Your One-Stop Weather Data Shop

While Meteomatics' focus remains on numerical weather models, such as our in-house developed 1-kilometer resolution models, the integration of AI-based forecasts supports our goal of serving as a one-stop weather data shop, meeting the varied needs of our customers.

90-Meter Downscaled Forecasts

The output of AI-based forecasting models will also benefit from Meteomatics' signature 90-meter downscaling feature. This advanced downscaling capability enhances the spatial resolution of weather data, providing users with highly localized forecasts tailored to their specific geographical areas of interest.
