Comparison of foE predictions of the two models at four stations. Black square: measurements (identified as Mea); Red dot: Predictions of the ITU model (identified as ITU); Blue triangle: Predictions of the PRO model (identified as PRO); Yellow bar: Error between measurements and ITU predictions (identified as |Mea-ITU|). Green bar: Error between measurements and PRO predictions (identified as |Mea-PRO|).
