Guidelines for Cloud Seeding to Augment Precipitation

Sponsored by the MOP 81 (4th Ed) Task Committeee of the Atmospheric Water Management Standards Committee of the Standards Development Council of the Environmental and Water Resources Instiute of ASCE Guidelines for Cloud Seeding to Augment Precipitation, MOP 81, Fourth Edition, provides practical details of using the cloud seeding technology. This newly revised manual incorporates pertinent background on the science and practice of weather modification by cloud seeding to augment precipitation. Topics include: Societal, environmental, and economic aspects of precipitation enhancement by cloud seeding Legal aspects associated with weather modification operations Scientific basis for cloud seeding for both summer and winter clouds Cloud seeding modes and technologies Guidance on how to implement a cloud seeding program, and Examples of operational cloud seeding projects and significant research programs in the western United States. This manual will provide water resources managers with the resources to make decisions regarding the use of cloud seeding to augment water supplies.
