Consequently, the ionosphere of Mars varies considerably from the day side to
the night side. The day side is also dependent on photoionization of atmospheric
neutrals by the solar EUV flux, solar cycle, solar rotation, solar flares, cosmic rays,
and gamma ray bursts, while the night side depends on neutral density, day-night
plasma transport, and recombination rates (Lillis et al. 2009 ). All these factors
combined with the Martian crustal magnetic field can produce some areas where
