Description

The ECMWF Artificial Intelligence/Integrated Forecasting System (AIFS) delivers a new class of global weather prediction based on advanced machine learning and deep learning methods. As a hybrid approach, AIFS fuses ECMWF's world-leading NWP techniques with neural networks, providing fast, data-driven forecasts at medium-range time scales, alongside traditional physics-based models.

AIFS global forecasts are produced on a 0.25° grid, providing 15-day (360 hour) outlooks with four cycles daily (00, 06, 12, 18 UTC).

As an experimental model, AIFS complements traditional IFS by leveraging AI for rapid scenario generation and postprocessing, accelerating research into weather extremes, renewable energy, agriculture, hydrology, and climate risk assessment. The data can be accessed in near real-time as JSON, CSV, or NDJSON through GribStream's standard API.

Detail

Product page: https://www.ecmwf.int/en/forecasts/datasets/open-data
Model Type: Global medium-range forecast using hybrid machine learning and physical modeling.
Grid & Frequency: 0.25° (~28 km) global grid, with 4 forecast cycles daily (00, 06, 12, 18 UTC).
Forecast Range: Up to 15 days per cycle: 3-hour steps through 144h, then 6-hourly to 360h.
Parameters: Comprehensive selection at both the surface and multiple pressure levels, supporting broad meteorological and environmental analysis.
Primary Use Cases: Machine learning benchmarking, fast ensemble postprocessing, energy forecasting, climate and extremes research, hydrological modeling, agri & food supply risk analysis, operational dashboards, and open data science.
