From the Weather Program Office of NOAA:

“Submission Information
Persons subject to reporting.
As stated in Vol. 83, No. 19 of the Federal Register dated Monday, January 29, 2018, the
Department of Commerce and the National Atmospheric and Administration requires that
persons who engage in weather modification activities in the United States shall provide reports
prior to and after the activity. This is Section 6(b) of Public Law 92–205.
All non-Federal weather modification activities must be reported to the U.S. Secretary of Commerce,
via the NOAA Weather Program Office. All reports submitted to NOAA are compiled and then
posted on the
NOAA Library Website.
Activities subject to reporting.
(a) The following, when conducted as weather modification activities, shall be subject to reporting:
(1) Seeding or dispersing of any substance into clouds or fog, to alter drop size distribution,
produce ice crystals or coagulation of droplets, alter the development of hail or lightning, or
influence in any way the natural development cycle of clouds or their environment;
(2) Using fires or heat sources to influence convective circulation or to evaporate fog;
(3) Modifying the solar radiation exchange of the earth or clouds, through the release of gases,
dusts, liquids, or aerosols into the atmosphere;
(4) Modifying the characteristics of land or water surfaces by dusting or treating with powders,
liquid sprays, dyes, or other materials;
(5) Releasing electrically charged or radioactive particles, or ions, into the atmosphere;
(6) Applying shock waves, sonic energy sources, or other explosive or acoustic sources to the
atmosphere;
(7) Using aircraft propeller downwash, jet wash, or other sources of artificial wind generation;
or
(8) Using lasers or other sources of electromagnetic radiation.
(b) In addition to the activities listed above, other similar activities falling within the definition of
weather modification as set forth in
§ 908.1
are also subject to reporting.
(c) The requirement for reporting shall not apply to activities of a purely local nature that can
reasonably be expected not to modify the weather outside of the area of operation. This exception
is presently restricted to the use of lightning deflection or static discharge devices in aircraft,
boats, or buildings, and to the use of small heat sources, fans, fogging devices, aircraft
downwash, or sprays to prevent the occurrence of frost in tracts or fields planted with crops
susceptible to frost or freeze damage. Also expected from the requirement for reporting are
religious activities or other ceremonies, rites and rituals intended to modify the weather.
(d) All activities noted in paragraphs (a)
and
(b)
of this section are subject to initial reporting.
However, after the Administrator has received initial notification of a planned activity, he may
waive some of the subsequent reporting requirements. This decision to waive certain reporting
requirements will be based on the general acceptability, from a technical or scientific viewpoint, of
the apparatus and techniques to be used.
(e) Other reporting exceptions may be made in the future by rule of the Administrator.
Is there a specific form to submit?
The following forms should be used:
●
17-4
- Initial Report on Weather Modification Activities (Approved Information collection
0684-0025)
●
17-4A
- Interim Activity Reports and Final Report (Approved Information collection
0648-0025)
When creating your reports, please use the following coding system as your NOAA file name: year,
state, first four digits of the project name, and the respective report number. For instance, for a
project that takes place in 2021 in Maryland and is titled Rock Canyon, the code would be
2021MDROCK-1 (initial report) and 2021MDROCK-2 (final report). You may also use this naming
convention to save your files prior to submitting.
How do I submit the form(s)?
Please submit reports via email to
weather.modification@noaa.gov
.
General Information
How long before my submission is available in the NOAA
Repository?
Submissions will usually be available in the repository within two (2) months after the end of the
fiscal quarter.
