# Third Party Models

The Jua platform provides access to several third-party weather models alongside our proprietary EPT models. These models can be accessed through both the platform interface and API.

## Available Models

### ECMWF Models

* **ECMWF IFS Operational** - ECMWF IFS HRES model, often referred as ops. See [ECMWF IFS](/models-and-products/third-party-models/ec-ifs.md) for details.
* **ECMWF IFS Ensemble** - Multiple ECMWF IFS Ensemble runs, often referred to as ENS. See [ECMWF IFS Ensemble](/models-and-products/third-party-models/ecmwf-ens.md) for details.
* **ECMWF AIFS** - EC's AI-based forecasting model [(learn more)](https://www.ecmwf.int/en/about/media-centre/news/2025/ecmwfs-ai-forecasts-become-operational)

### NOAA Models

* **GFS** - Global Forecast System from NOAA. See [GFS NOAA](/models-and-products/third-party-models/gfs-noaa.md) for details.
* **GFS Ensemble Mean** - Average of multiple GFS ensemble runs

### AI Models

* **Microsoft Aurora** - Microsoft's AI-based global weather model. See [Microsoft Aurora](/models-and-products/third-party-models/microsoft-aurora.md) for details.
* **GFS GraphCast** - Google DeepMind's ML-based weather prediction model, initialised by GFS. See [GFS GraphCast](https://github.com/juaAI/docs/blob/main/models-and-products/third-party-models/gfs-graphcast.md) for details.

### DWD Models

* **ICON Global** - Global model from DWD (Deutscher Wetterdienst). See [DWD ICON Global](/models-and-products/third-party-models/dwd-icon-global.md) for details.
* **ICON-EU** - Higher-resolution regional European model from DWD (Deutscher Wetterdienst). See [DWD ICON-EU](/models-and-products/third-party-models/dwd-icon-eu.md) for details.

### Regional Models

* **AROME France HD** - High-definition regional model from Météo-France

### Open Meteo Models

Additional models are available through [Open Meteo](https://open-meteo.com/en/docs/), including ECMWF AIFS/IFS variants, GFS/NCEP models, and regional European models (ICON-D2, KNMI HARMONIE-AROME, AROME France HD, UKMO). These models have some restrictions: point queries, no streaming, latest forecast, and nearest interpolation. See [Open Meteo Models](/models-and-products/third-party-models/open-meteo.md) for the full list.

## Hindcasts

The following hindcast datasets are available:

* **ECMWF AIFS** - Historical forecast data available for performance analysis and evaluation. See [ECMWF AIFS](/models-and-products/third-party-models/ecmwf-aifs.md) for details.
* **ECMWF IFS Operational** - Historical forecast data available. See [ECMWF IFS](/models-and-products/third-party-models/ec-ifs.md) for details.
* **GFS NOAA** - Historical forecast data available. See [GFS NOAA](/models-and-products/third-party-models/gfs-noaa.md) for details.
* **Microsoft Aurora** - Hindcast data available. See [Microsoft Aurora](/models-and-products/third-party-models/microsoft-aurora.md) for details.

## API Access

All models are accessible through the [Query Engine API](/api-v2/getting-started.md) using the `POST /v1/forecast/data` endpoint or the [Python SDK](/python-sdk/weather/forecast.md). Specify the model name using the API model strings shown in the tables above.

For complete API documentation, please refer to our [API Reference](https://query.jua.ai/docs).
