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.
