“…Note IRI2016 does not provide We have plotted the production and loss rates of NO + and  2 N in Figures 2 and 3. The electron impact production profile of NO + is taken from (Vialatte et al, 2017) and the loss from our model is calculated by: ∑ s l is n i , where the summation is over species s. We note that for the loss of NO + the only significant reaction is R10, which represents ion recombination. Other loss reaction (R1 -R6) have minimal effect since the maximum value of the loss rate is about 10 −9 cm −3 s −1 .…”

“…Results are obtained for local times between 1.5 and 2.5 h. The modeled and empirical (IRI2016) values of NO + and

N_{2}^{+}

ion densities are shown as a function of height in Figure 1 including electron precipitation and for medium magnetic activity. Note that results are limited to a maximum altitude of 300 km because production data needed to calculate NO + densities are only available to this altitude (Vialatte et al., 2017). Below 94 km altitude there is a good agreement between modeled and IRI NO + densities, but above 94 km there is a relatively large difference between the two.…”

“…We applied the transport effect at the E region in which these latter assumptions are valid. NO + and

N_{2}^{+}

productions are calculated using the TRANSSOLO model which was previously developed to solve Boltzmann equation for electrons transport in the atmosphere (Lummerzheim et al., 1989; Lummerzheim & Lilensten, 1994; Vialatte et al., 2017). By including the flux intensity and the corresponding cross section, we can derive the ionization.…”

“…The electron flux mean energy is E 0 = 500 eV for a total flux of 0.1 erg . cm −2 which corresponds to weak solar and geomagnetic activity at high latitude (Vialatte et al., 2017). A Maxwellian distribution, an isotropic distribution in energy and pitch angles are used to simulate electron precipitation (Hardy et al., 1985).…”

“…The data on which this article is based are available in Vialatte et al. (2017), Harris and McGhan (1977). IRI2016 and MSIS90 ion density, neutral density and temperature are used as initial conditions to implement the numerical program at t = 0 and to calculate loss rates due to chemical reactions.…”

Of particular importance to nitrogen atoms is the nitric oxide ion (NO +) known to be the most abundant ion species in the E region (Furuya et al., 2017). Also, NO + has the lowest heat of formation of the major thermospheric ions and can give rise to neutral products only by dissociative recombination but it is produced by reactions involving all other ions (Duff & Smith, 2000; Oppenheimer et al., 1977). It is also found that NO + is the dominant ion in O + depleted regions (Szuszczewicz, 1978) and gradually increases above 100 km altitude (C. Smith et al., 1967). Moreover, chemical reactions involving NO + can explain
