SWIF Model

The SWIF ionospheric forecasting algorithm provides alerts and warnings for upcoming ionospheric storm disturbances and ionospheric forecasts over Europe. SWIF combines historical and real-time ionospheric observations with solar wind parameters obtained in real time at L1 point through the cooperation of an autoregression forecasting algorithm, namely TSAR that provides real-time ionospheric forecasts up to 24 hours ahead during all possible conditions with an empirical method, namely STIM, that formulates the ionospheric storm-time response triggered by solar wind disturbances.
