On the Master, Uman, Lin, Standler and the Modified Transmission Line lightning return stroke current models

The lightning return stroke model by Master, Uman, Lin, Standler (1981) (MULS), a modification of the Lin, Uman, Standler (1980) (LUS) model, can be viewed mathematically as having a specified channel-base current, although in the original formulation it was the channel current sources that were specified. The specification of the MULS channel-base current is independent of the time dependence of the corona current sources which characterize the MULS model. Further, when starting from the same channel-base current, the MULS return stroke model, except for the uniform current component, is mathematically equivalent to the Modified Transmission Line (MTL) model. For both the MULS and the MTL models the authors present a single analytical expression relating the far fields and the channel-base current. This formulation provides a simple procedure to infer MULS channel-base currents from remote electric and magnetic field measurements and hence to test the MULS model
