ASCE/EWRI 44-05 presents the standard practice for conducting supercooled fog dispersal operational programs. Extended periods of fog can have large economic impacts on aviation, tourism, transportation, and mining industries; as well as a negative effect on agriculture. These problems can be reduced through the use of state-of-the-art supercooled fog dispersal technologies. This document describes the process through which such operations should be designed and conducted. It also provides the reader with information on the planning, conduct, and evaluation of such efforts. Topics include: history and status of supercooled fog dispersal technology; fog characteristics; project design and seeding agent delivery methods; operations manual; and evaluation of projects.
