Weather Modification Project Reports

Weather Modification Project Reports


Publication History & Scope

In the late 1940's and 1950's many deemed "the deliberate or the inadvertent alteration of atmospheric conditions by human activity", also known as weather modification, as a promising science of the future. Currently, the most common form of weather modification is cloud seeding, which increases rain or snow, usually for the purpose of increasing the local water supply. Weather modification can also have the goal of preventing damaging weather, such as hail or hurricanes, from occurring.  

As part of Public Law 92-205 (1972), all non-Federal weather modification activities must be reported to the U.S. Secretary of Commerce, via the NOAA Office of Weather and Air Quality.  Below is a list of these reports and is updated on an annual basis.
