High frequency (HF) radio wave propagation depends on the ionosphere status which is changed with the time of day, season, and solar activity conditions. In this research, ionosonde observations were used to calculate the values of maximum usable fre

In the Sun, particles mostly protons (positively charged) with energies up to several hundred (MeV) are escaped during periods of intense flare activity. These particles are solar cosmic radiation, which are very small particles move at nearly the sp

The purpose of this research work is to validate the ionospheric models (IRI and CHIU) to assess its suitability and usefulness as an operational tool. The ionospheric model is a computer model designed to predict the state of the global ionosphere f
