Study the diurnal variation of the thermospheric parameters due to the effect of solar activity for third month of the year

الملخص EN

The upper atmospheric parameters variation have been studied under the effect of solar activity at altitude of low artificial satellites 500km.

The atmospheric parameters have been determined for three days of the third month of the year from through their influence by the solar flux index F10.7 and geomagnetic activity index Kp for different solar conditions.

This study base on Drag Temperature Model (DTM) model by computer program to study these variations.

The results show that these parameters are changing due to the change in solar activity parameters.
