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 Model
- NAM Model
- HRRR Model
- ICON DWD Model
- ECMWF Model
- SILAM Model
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.
