The proposed project focuses on the detection of lightning flashes above mesoscale convective systems routinely observed during the summer in the high plains of the Midwest. The investigation entails the use of radio wave diagnostics to examine the production of ionization patches (if any) in the stratosphere and mesosphere. A three-week campaign is proposed for summer 1995; the experimentation period will be timed to take advantage of ground- based optical diagnostics that will be in place for the detection of sprites and blue jets. If the proposed observing strategy is effective, more complex diagnostic systems can be implemented to precisely define the atmospheric physics involved in the optical sightings.

拟议项目的重点是检测中西部高原夏季常规观测到的中尺度对流系统上方的闪电。 该调查需要使用无线电波诊断来检查平流层和中间层中电离斑块（如果有）的产生。 建议在 1995 年夏季开展为期三周的活动；实验期间将利用地面光学诊断技术来检测精灵和蓝色喷射。 如果所提出的观测策略有效，则可以实施更复杂的诊断系统来精确定义光学瞄准中涉及的大气物理学。
