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 for details.

  • ECMWF IFS Ensemble - Multiple ECMWF IFS Ensemble runs, often referred to as ENS. See ECMWF IFS Ensemble for details.

  • ECMWF AIFS - EC's AI-based forecasting model (learn more)

  • ECMWF AIFS Ensemble - EC's AI-based ensemble (control + 50 perturbed members). See ECMWF AIFS Ensemble for details.

NOAA Models

  • GFS - Global Forecast System from NOAA. See GFS NOAA 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 for details.

  • GFS GraphCast - Google DeepMind's ML-based weather prediction model, initialised by GFS. See GFS GraphCast for details.

DWD Models

  • ICON Global - Global model from DWD (Deutscher Wetterdienst). See DWD ICON Global for details.

  • ICON-EU - Higher-resolution regional European model from DWD (Deutscher Wetterdienst). See DWD ICON-EU for details.

Regional Models

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

Open Meteo Models

Additional models are available through Open Meteo, 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 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 for details.

  • ECMWF AIFS Ensemble - Historical ensemble forecast data available. See ECMWF AIFS Ensemble for details.

  • ECMWF IFS Operational - Historical forecast data available. See ECMWF IFS for details.

  • GFS NOAA - Historical forecast data available. See GFS NOAA for details.

  • Microsoft Aurora - Hindcast data available. See Microsoft Aurora for details.

API Access

All models are accessible through the Query Engine API using the POST /v1/forecast/data endpoint or the Python SDK. Specify the model name using the API model strings shown in the tables above.
