• Title: Weather Modification Reporting Program - 1973-1978
• Date: 6/1/1979
• Weather Modification - Doc Type: Report

~ ,I

weather modification activities carried out in or over the territory of
either country within 200 miles of their international boundary. The
Atmospheric Environment Serivce is the Canadian agency designated to
implement the information exchange with NOAA. On a broader scale, NOAA
provides information on annual activities in the United States to the
World Meteorological Organization for publication in its yearly "Register
of National Weather Modification Projects", a compilation of experiments
and operations conducted within member countries.

The reporting procedures include the submittal of Initial, Interim,
and Final Reports covering weather modification activities for individual
target areas. An Initial Report is required at least 10 days prior to
the start of the activity. Interim Reports are required for those pro-
jects active on January 1 of each year and must be filed within 45 days
from that date. A Final Report is to be submitted within 45 days after
completion of the weather modification activity or project. A weather
modification activity is considered active until a Final Report is filed
with NOAA.

A project may be carried out intermittently at one location for one
or more years, or a project may begin and end within a year. Often,
projects are completed early in a year and restarted near the end of
that year at the same location with the same techniques. In this case,
only one project at the one location would be used in summarizing the
mnnber of proj ects and target areas for the calendar year'; however
the seeding data for both projects at the one location are used in
preparing summary information.

Part I of this summary report covers nonfederal and Federa1ly-
sponsored weather modification activities reportec to NOAA in calendar
years 1976, 1977, and 1978. It includes analyses of data on project
purposes, sponsors, operators, target locations, target areas, modi-
fication techniques, apparatus, and seeding agents. Additional
information is provided on the number of modification days, duration
of seeding activities, and amounts of seeding agents. Also included
is a discussion of reported information on operational safeguards and
environmental impact associated with weather modification activities.
