A program was conducted to gain experience and document progress towards development of a concept for a Laser-Induced Lightning Experiment LILE. The purpose of the program was to develop a method for triggering natural lightning discharges using pulsed lasers and verify theoretical predictions. The technique shows great promise in shortening the acquisition period for obtaining necessary lightning parameter data needed for more realistic Lightning Simulation Tests LST and more definitive Lightning Transient Analyses LTA. To achieve the intended objective within the restrictions of availability, an experimental method was designed, a test locale selected, test parameters were defined, test apparatus designed and test instrumentation selected andor developed. Although the required climatic conditions did not develop during the experimental period, all other phases of the program were successfully accomplished and will facilitate future experiments. Small scale experiments were also performed to investigate spark gap triggering using laser beams, laser beam effects on electromagnetic fields, and laser powerenergy scaling. Author
