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.
