Daytime GNSS scintillation due to Es over Arabian Peninsula during low solar activity
Abstract
A constant presence of daytime GNSS phase (σϕ) and amplitude (S4) scintillation during the times sporadic-E (Es) was observed, is reported. The most favorable local time (LT) of the day for the occurrences are the morning (08:00 to 12:00) and the late afternoon (16:00 to 18:00) hours. Es and σϕ/S4 are found to be in very good correlation. Low occurrences of post-sunset scintillation suggest that the main driver of the ionospheric scintillation over Arabian Peninsula during the low solar activity period is the presence of Es.
