Abstract:
An evaluation of the effectiveness of airborne chemical fog dispersal techniques employed at the Seattle-Tacoma and Spokane International Airports, Washington, was conducted during the 1971-72 winter season. Measurements of meteorological and fog parameters, combined with visual and photographic observations made during a three-month field period, were subjected to interpretive analysis the analysis resulted in the assignment of 25 percent and 57 percent effectiveness ratings for the Sea-Tac and Spokane fog dispersal program, respectively. Immediately apparent environmental impact of these operations was judged to be minimal. A substantial body of evidence was acquired which indicates that heat is more effective than chemicals in local dissipation of both warm and cold fogs. Author
