Results of an Exploratory Experiment within the Greek National Hail Suppression Program
AbstractDuring the summers of 1984 and 1985 a multi-area operational hail suppression program was conducted in northern and central Greece, sponsored by the Greek National Agricultural Insurance Institute. This operational program included a small exploratory randomized cross-over seeding experiment embedded within one of the three operational project areas. This article summarizes the experiment’s design, the network hailpad data and the initial analyses and results. Substantial reductions (e.g., 30 to 75%) in the area of coverage, hailstone size, and concentration are apparent in the two sumuners’ data, and the combined two season sample provides correspondingly strong inferential two-tailed P-value support (e.g., .08 to .02) for evidence of treatment effects.
