Abstract : Foggy Cloud III, Phase I is part of a continuing series of experiments concerning the modification and dispersal of warm fog and stratus clouds. Tests were conducted at the Arcata-Eureka Airport, Humboldt County, Calif. from 27 July to 24 October 1970, using fixed-wing aircraft as delivery vehicles. The seeding agents were (1) a solution of ammonium nitrate, urea, and water developed during Foggy Cloud I, and (2) water. Of the 19 seeding tests, 17 showed some response to seeding. The results of seeding seven fogs classified as steady-state were completely successful, with ceilings and visibilities improved sufficiently to permit normal flight operations. (Author)
