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.
