A friendly reminder that in the U.S., as a non-government organization, if you’d like to modify the weather you need to fill out the NOAA form 17-4(a).

This is required by U.S. Code 15§ 330a as per Public Law 92-205 (1972): https://www.law.cornell.edu/uscode/text/15/330a

All weather modification projects that have been filed with the NOAA under this law can be found here: https://www.library.noaa.gov/Collections/Digital-Collections...

It’s important to note that religious ceremonies are exempted from this law. NOAA form 17-4(a) does not need to be submitted for rain dances or other religious ceremonies intended to change the weather. This, however, is likely to change if the success rates of your weather ceremony become statistically significant.
