Five hundred and fifty one (551) rockets and 789 flares were used during seeding operations. Also, of particular note, was the presence in the field of seven (7) Doppler radars. These observations will provide scientists with data by which detailed analysis of the airflow within severe convective storms can be made. This research was performed as part of the National Hail Research Experiment, managed by the National Center for Atmospheric Research and sponsored by the Weather Modification Program, Research Applications Directorate, National Science Foundation.
