Auroral precipitating electrons pass through an acceleration region before entering the atmosphere. Regardless of what produces it, a parallel electric field is assumed to cause the acceleration. It is well known that from kinetic theory an expression for the corresponding upward field-aligned current can be calculated, which under certain assumptions can be linearized to jE"K». The K constant, referred to as the Lyons-Evans-Lundin constant, depends on the source density and thermal energy of… CONTINUE READING
