Nemec et al. (2011) Empirical model of the Martian dayside ionosphere

with Nemec et al. (2016) improvement at higher altitudes (|B| and F10.7 dependencies)

Note 1: For a given combination of input parameters, the model returns electron densities as a function of the altitude, i.e., the electron density profile.
Note 2: IDL source code of the model is available here.

SZA (deg): (obligatory)

year month day hour (recommended, adds F10.7 and Sun-Mars distance dependencies); alternatively: Sun-Mars distance (AU) F10.7

latitude (deg) east longitude (deg) (optional, adds crustal magnetic field effects, affects primarily higher altitudes); alternatively: |B|400 km (nT)
