Additional Resources for Purchase
HAIL SUPPRESSION STANDARD
Guidelines for Operational Hail Suppression Programs, ASCE/EWRI 39-15 describes the process for designing, conducting, and evaluating operations to suppress the formation of hail. Hail is the product of vigorous, deep convection in the atmosphere. The most common approaches to hail suppression involve seeding a storm with nucleating agents using airborne, ground-based, or rocket and artillery delivery systems. Click Here to Purchase
PRECIPITATION ENHANCEMENT STANDARD
Standard Practice for the Design, Conduct, and Evaluation of Operational Precipitation Enhancement Projects, ASCE/EWRI 42-17 provides an introduction to the history and technology of cloud seeding and describes the scientific basis for examining the efficiency of both natural precipitation and human-induced weather modifications. This standard covers design aspects of precipitation enhancement projects, including project scope, seeding agents, targeting and delivery methods, meteorological data, deployment of equipment, legal issues, and environmental concerns. Operational issues such as manuals, personnel requirements, decision-making hierarchy, communications, safety, and public relations, are considered. Finally, the components of project evaluation, including project design constraints, evaluation measures, and dissemination of results, are surveyed. Click Here to Purchase
GUIDELINES FOR CLOUD SEEDING TO AUGMENT PRECIPITATION
Manuals of Practice MOP 81 (2016) 3rd Edition, supplies the practical details for implementing a cloud seeding project to enhance precipitation efficiency. This revised edition incorporates pertinent information on the background, science, and practice of weather modification developed in the last 10 years. Click Here to Purchase
SUPERCOOLED FOG DISPERSAL STANDARD
Standard Practice for the Design and Operation of Supercooled Fog Dispersal Projects, ANSI/ASCE/EWRI 44-13 presents guidelines for programs aimed at dispersing supercooled fog. This standard describes the process through which supercooled fog dispersal operations should be designed, conducted, and encompasses topics such as project scope, delivery methods, seeding agent selection, targeting and delivery, and suspension criteria.
