EFFECTIVENESS OF FOG DISPERSAL TECHNIQUES AT SEATTLE-TACOMA AND SPOKANE INTERNATIONAL AIRPORTS

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/
