Ionospheric or tropospheric scintillation

WebTransionospheric radio signals might undergo random modulations of their amplitude and phase caused by scattering on irregular structures in the ionosphere. This phenomenon, known as scintillation, is governed by the space weather conditions, time of WebScintillation is predominantly a night time phenomenon in the equatorial region occurring for more than 40% of the year during the 20:00-02:00 local time period. It also shows a strong seasonal dependence with a pronounced minimum at the southern solstice and relatively high scintillation activity at the northern solstice.
