On this page the forecasts of the following quantities are shown:

  • DNI (Direct Normal Irradiation) indicates the mean value - pertinent to the diurnal arc - of the direct solar irradiation at ground level on the plane orthogonal to the direction of the solar rays (the extra-atmospheric value on each of the three considered days is about: 1366 W/m2)

  • daily DNI  indicates the cumulative direct solar energy relative to the considered day expressed by Wh/m2 (the extra-atmospheric value on each of the three considered days is about: 17283 Wh/m2)

  • Variability indicates the temporal trend of the solar irradiation during the considered day

  • Weather represents the predicted cloud cover
