Guidelines for Cloud Seeding to Augment Precipitation

Abstract

Preparation of guidelines for cloud seeding was initiated by the ASCE Weather Modification Committee and is authored by a group of six experts in the field of weather modification. It is designed to give guidance to water resources managers who might become involved in the decision‐making process for implementing a weather modification project. The sections cover a variety of aspects of weather modification including the social, legal, environmental and economic issues as well as the scientific basis. The technical details of various devices for producing artificial nuclei, and the various methods for distributing the artificial nuclei through cloud masses are described in detail. Finally, there is a section that outlines the steps that must be taken to implement a cloud seeding project.
