“…Coulomb collisions, and long range interactions, i.e. the Cherenkov emission of plasma waves [ Perkins , 1965; Itikawa and Aono , 1966]. Furthermore, for electrons with energies above 14 eV additional quantum mechanical corrections must be considered [ Schunk and Hays , 1971].…”

[1] In order to improve model comparisons with recently improved incoherent scatter radar measurements at the Jicamarca Radio Observatory we have added photoelectron transport and energy redistribution to the two dimensional SAMI2 ionospheric model. The photoelectron model uses multiple pitch angle bins, includes effects associated with curved magnetic field lines, and uses an energy degradation procedure which conserves energy on coarse, non-uniformly spaced energy grids. The photoelectron model generates secondary electron production rates and thermal electron heating rates which are then passed to the fluid equations in SAMI2. We then compare electron and ion temperatures and electron densities of this modified SAMI2 model with measurements of these parameters over a range of altitudes from 90 km to 1650 km (L = 1.26) over a 24 hour period. The new electron heating model is a significant improvement over the semi-empirical model used in SAMI2. The electron temperatures above the F-peak from the modified model qualitatively reproduce the shape of the measurements as functions of time and altitude and quantitatively agree with the measurements to within $30% or better during the entire day, including during the rapid temperature increase at dawn.

“…We present only the necessary formulae for understanding the heating rate derivation. The argument of the logarithm in the final results (A4) and (A5) is identical with the logarithm of Kihara and Aono [1963] but differs from the results of the later paper of ltikawa and Aono [1966], where arbitrary velocity 1) was allowed. In the latter, the logarithm is split into a term independent of 1) and a complicated function, G, containing the 1) dependence.…”

“…The more exac4 energy loss rate of Itikawa and Aono (1966) which includes collective wave-particle and wave-wave effects, was substituted for the approximate loss rate without being included in an ab initio manner. The derivation presented here includes collective plasma interactions ab initio by employing the electron-electron collision operator of , using their unified theory.…”

The thermal electron heating rate, Qe , is an important heat source term in the ionospheric electron energy balance equation, representing heating by photoelectrons or by precipitating higher energy electrons. A formula for the thermal electron heating rate is derived from the kinetic equation using the electron-electron collision operator as given by the unified theory of Kihara and Aono. This collision operator includes collective interactions to produce a finite collision operator with an exact Coulomb logarithm term. The derived heating rate Qe is the sum of three terms, Q e = Qp + S + Qint, which are respectively: 1) primary electron production term giving the heating from
