II. Specific qualifications of applicant

C. Methods of expertise and project experience

1. Airborne AgI seeding: Applicant was assistant to project leader
(1978-80) during a research program at Utah State University. During
this program seeding aircraft using acetone type generators were directed
to seed for specific periods of time and at a specific rate. Detailed
cloud physics measurements were then made. Additional expertise in air~
borne seeding has been gained while being an assistant meteorologist. in
a summer (1978) hail suppression project in Southwestern North Dakota.
During this project several aircraft using acetone type generators, burn
in place pyrotechnics, and ejectable pyrotechnics were directed to po-
tential hail producing cloud systems. The aircraft were then instructed
as to where to seed and at what rates to seed these cloud systems.

2. Ground based AgI generators: Applicant helped conduct research
(1981) on the behavior of plumes generated from ground based generators
during an operational project in Southern Utah. Applicant is familiar
with the operation of ground generators, seeding rates of generators,
and meteorological conditions under which the generators best function.

3. Balloon-borne cloud seeding: Applicant is assistant to the project
leader of an ongoing research program at Utah State University where
balloon-borne seeding has been used. Seedable clouds are detected by
means of remote sensing equipment (dual frequency microwave radiometer
and Ka-band radar) and then seeded using either pyrotechnic or acetone
based payloads. Currently the acetone payload is preferred. During the
research program detailed measurements are made using ground based and
remote sensing equipment.
