The API utilizes multiple short/mid-range high resolution, and coarser resolution long-range models to construct forecasts. These models include the following models:
- GFS
- NAM
- HRRR
- ICON DWD
- ECMWF
- CAMS
- SILAM
- ACCESS
- JMA
- AROME
Additionally, the API dynamically selects the best available models based on past performance, and then corrects each model for biases to produce the most accurate forecast possible.
