<br />this seeding technology. On the basis of the forecast and observed <br />meteorological parameters of the cloud systems over the pro:ject <br />seeding area, cloud systems with parameter values indicating more <br />precipitation augmentation potential would be consistently treated <br />with higher seeding rates. Cloud systems with lower precipitation <br />augmentation potential would be consistently treated with lower <br />seeding rates. A suggested procedure for determining seeding <br />rates is presented in Appendix B, which utilizes the following <br />meteorological inputs: <br />(1) Cloud depth <br />(2) Cloud base moisture <br />(3) Temperatures at established levels for pre-trough and <br />post-trough cloud systems. <br />Very detailed logs and records must be maintained of all <br />observed and forecast parameters considered in recognizing and <br />determining the period of suitable cloud and atmospheric con- <br />ditions for random seeding treatment proposed in this program <br />design. A complete list of weather data and equipment for <br />special meteorological observations will be presented in a later <br />section of this program design from which these assessments can <br />be made by competent meteorologists. <br /> <br />c. Seeding Delivery Systems and Seeding Materials - For the <br />purpose of designing the actual generator network for this program, <br />three modes of seeding have been incorporated. Two of these modes <br />would incorporate the use of ground-based cloud nuclei generators <br />and a third mode would consist of or include aircraft seeding. It <br />is estimated that approximately 70 percent of the cloud systems <br />assessed as suitable for seeding can effectively be seeded with a <br />network of ground-based cloud nuclei generators located near <br />occupied residences or remotely controlled and located in higher <br />foothill regions near the primary seeding area. Of the remaining <br />30 percent of seedable cloud systems, about half could be effec- <br />tively seeded by several aircraft maintaining a reasonably contin- <br />uous seeding plume comparable to a plume concept produced by a <br />network of ground-based generators. The remaining half of the <br />30 percent of the seedable clouds would have unsatisfactory <br /> <br />-26- <br /> <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />
