This grant supported the initial development of a deployable system for determining the structure of lightning discharges in three spatial dimensions and time. The purpose of this was to utilize the system to characterize lightning discharges that initiate sprites in the upper atmosphere. The grant also supported observations of sprites themselves using low-light-level video cameras and studies which identified charge transfer occurring within the sprite itself. This work resulted in the first high-speed video observations of sprites and the first recognition that significant charge transfer was occurring in sprites. Finally, it provided partial support for improving dual-polarization radar techniques for observing storms.
