Overview

ECMWF's operational AI forecasting system with deterministic and ensemble 15-day predictions

Key Features

AIFS is the European Centre for Medium-Range Weather Forecasts' operational machine-learning forecasting system. It runs deterministic and ensemble forecasts four times daily, covering global atmospheric variables at roughly 0.25-degree resolution out to 15 days. AIFS v2 adds operational wave and snow-cover predictions, and its open forecast data can be downloaded, redistributed, and incorporated into research or commercial weather products with attribution.
