Ionospheric Data



Figure 1 - Last ionogram. The dependence of the amplitude of the ranged signal on the frequency and effective height. The graduations of amplitude intensity are presented to the right of the graph.


Figure 2 - Critical frequencies without sporadic layers. Dependence of the critical frequencies of the ionosphere on the local time.


Figure 3 - The dependence of the critical frequencies of the ionosphere on the local time.


Figure 4 - The dependence of the critical frequencies of the ionosphere on the local time.


Local time is expressed in hours of Tomsk summer standard time (TSST). TSST = UTC + 7 hours.
