Analytical study for the annual TEC parameter variations for the solar cycle 24 over Iraqi Zone

الملخص EN

In this research, the TEC parameter has been determined for the ionosphere layer over the Iraqi zone.

The calculations of this parameter have been conducted using the IRI model that considered as one of the recommended international models which used to calculate the ionosphere parameter (TEC).

The determinations have been made for several sites or sites that located within the Iraqi territory.

The years (2011-2013) of the solar cycle 24 have been adopted to make the determinations for the TEC parameter.The capital Baghdad has been selected to represent the transmitter station and many different communication points which are located in different directions around the transmitter station have been represented as receiving stations.
