Field Evaluation of Pyrotechnic Cloud Seeding Devices at Lemmon, South Dakota, 17-21 July 1967,
Abstract
Between 17 and 21 July 1967 a number of experiments were conducted in the general vicinity of Lemmon, South Dakota to evaluate the effectiveness of pyrotechnic cloud seeding devices. Six test cases were treated, with the amount of silver iodide released into a cloud varying from 50 grams to over 7500 grams. Data are presented which indicate certain cloud reactions which appear to be characteristic of pyrotechnic seeding, among which are the development of a distinct cirrus shield and the occurrence of soft hail.
