<br />Recommended data analysis methods include comparisons of seeded and nonseeded time series of <br />precipitation rate and ice particle concentrations, habits, and sizes. Several existing software <br />packages are suggested for aiding the determination of seeded volumes, and for producing results <br />in easily comprehended graphical displays. <br /> <br />The area likely to be affected by the limited seeding during physical experiments was estimated, as <br />was the amount of the increase. It appeared unlikely that the proposed seeding would have any <br />discernible influence beyond a 20-km radius from Allen Lake. The seasonal increases in this area <br />might range from a maximum of 4 percent to about 1 to 2 percent. Corresponding melted snow <br />precipitation increases during a normal month should be less than 4.5 mm with snow depth <br />increases less than 45 mm, The primary reason why only very small increases are anticipated is that <br />only a small fraction of the total time with storms would be seeded over the course of any winter. <br /> <br />Experimental coordination and organization are addressed. It is recommended that a "nowcasting" <br />rather than a forecasting approach be taken in determining when to commence experiments. That <br />is, current observations of the weather over the Mogollon Rim and that approaching the rim would <br />be used in deciding when to conduct an experiment, and what type to attempt. A single contractor <br />is suggested for all ground-based functions and for operation of the seeding aircraft so all seeding <br />would be the responsibility of a single group, A second contractor should furnish the cloud physics <br />aircraft, which would have a highly specialized function, A third contractor should perform all <br />analysis, design improvements as knowledge is gained, and report scientific findings. <br /> <br />v <br />
