The characteristics of lightning, artificially induced by wire-trailing rockets were measured in a cooperative program involving investigators from France, from the Flight Hazards Branch of Wright-Patterson Air Force Base and from New Mexico Institute of Mining Technology. Lightning currents ranging from a few hundred amperes to a peak of 79 kA were measured. The waveforms of the electromagnetic signals produced by the lightning had associated magnetic field variations in excess of 10 Ts with rise times ranging from 40 ns to 1 microsecond. The development of an 11 cm radar was completed for a determination of the interaction between lightning and the surrounding atmosphere. Preliminary data on lightning echoes have now been obtained with it.
