Firstly, three popular ionosphere models (Klobuchar model, IRI and JPL GIM) were compared with grid TEC. Then CNC TEC Map using Kriging method with constant drift, linear drift and quadratic drift were compared with each other. Then TEC map derived from nearest neighbor method, polynomial regression method (order=5) and Kriging method with different temporal resolution of 5 minutes, 30 minutes and 120 minutes were compared.

During years of exceptionally high sunspot activity, as was the case in 1990 and 1991, the F-layer of the ionosphere is capable of refracting signals above 54 MHz.

The statistic results showed that: Compared with the earward flow from the midtail, the nearEarth low latitude tailward flow from the ionosphere is characteristic of the lowtemperature and high density; With the tailward flow moving from the lobal region to the plasma sheet, the velocity of the tailward flow decrease, the density and the temperature increase. The tailward flow has distinct anisotropy depending on the difference of the parallel with perpendicular temperature.
