Title

LOCALTIME AND SEASONAL VARIATIONS OF foF2 AND foF3 IN DIFFERENT SOLAR ACTIVITY CONDITIONS

Abstract

foF2 and foF3 as a function of local time (during 07:00-18:00 LT) and day of the year based on ionosonde observations. Local time variations of foF2, foF3 and the difference of foF2 and foF3, foF3-foF2 in different seasons and different solar activity conditions. Since the F3 layer is formed by plasma transport, foF3-foF2 is expected to provide some insight into the local time variations of plasma transport. For seasonal analysis, 10 February-9 May as March equinox, 10 May-9 August as summer, 10 August-9 November as September equinox, and 10 November-9 February as winter. Mean and standard deviation (SD) of FoF2, foF3 and foF3-foF2, respectively, observed in different seasons (March equinox, summer, September equinox and winter) and different solar activity conditions. To illustrate seasonal variations we show mean and SDs of foF2, foF3, and foF3-foF2, for three local times, viz., 10:00, 13:00 and 16:00 LT as a function of day number Observations made for three different stations namely Jicamaca,Kwajalein and Madimbo. Low-latitude F2 layer critical frequency (foF2) is directly related to the formation of the F3 layer, which varies remarkably with season and solar activity . Solar activity dependence of low-latitude ionospheric foF2 has been studied based on observations made from three stations (Kodaikanal, Ahmadabad and Delhi) in the Indian sector. They also found saturation in foF2 for high values of F10:7 (> 120 sfu) similar to that shown here. They found that at the equatorial station Kodaikanal foF2 values in equinoxes are roughly equal to or slightly higher than those in winter and the winter values of foF2 are always higher than those of summer
