Uniform : Pederson Conductance = p [mhos], Hall Conductance = h [mhos]
Semi-Empirical Auroral (BATSRUS): Model uses solar EUV ionization empirical model
that depends on solar 10.7 cm flux and the solar zenith angle, nightside background conductance,
auroral oval conductance
(empirical relationship between the field-aligned currents and local
conductance derived using the AMIE technique), and constant polar cap conductance.

Semi-Empirical Auroral (Open GGCM): Model uses solar EUV ionization empirical model
that depends on solar 10.7 cm flux and the solar zenith angle,
model for the mean energy and energy flux of precipitating magntospheric electrons,
and
empirical relationship between electron precipitation parameters
and local conductance (Robinson Formula).
Diffuse electron precipitation is specified by the plasma temperature in the plasma sheet.
Discrete electron precipitation (auroral electrons accelerated by a potential drop in regions
of upward field-aligned current) is modeled using
Knight Relation.
