ASCE 44-20 PDF Download

The ASCE 44-20 standard provides guidelines for programs aimed at dispersing supercooled fog. Supercooled fog can have significant economic impacts on various industries, including aviation, tourism, transportation, and mining, as well as negative effects on agriculture. This standard describes the process of designing, conducting, and evaluating supercooled fog dispersal operations, including recent technological advancements.

The standard begins with a review of supercooled fog dispersal technology, followed by an overview of fog characteristics. The design of these projects covers aspects such as project scope, delivery methods, seeding agent selection, targeting and delivery considerations, and seeding suspension criteria. The standard also addresses the operational aspects of conducting a dispersal project, including the operational manual, personnel requirements, decision-making processes, communications, and public information and safety considerations. Additionally, methods of evaluating the success of a dispersal project are described.

ASCE 44-20 is particularly valuable to professionals in the fields of hydrology, hydrometeorology, environmental and water resources engineering, airport and mining operations management, water management agencies, surface transportation management, and others who deal with the challenges posed by supercooled fog. The standard provides a comprehensive framework for effectively designing, operating, and evaluating supercooled fog dispersal projects, considering both technical and safety aspects.
