Formation of Ray Trajectories of HF Radiowaves in Midlatitude and Highlatitude Ionosphere During Halloween Storm 2003 According to Radiotomography Data

The satellite radio tomography of the ionosphere is an efficient method for electron density imaging in the different geographical regions of the world under different space weather conditions. In this work we used low orbital radio tomography approach to study ionospheric disturbances in Russian sector along Svalbard-Murmansk-Moscow line during famous Halloween Storm 2003. Obtained tomographic cross-sections of electron density served as a media to model the peculiarities of the formation of ray trajectories of HF radio waves during this storm.
