COSE III DATA SUMMARY LOGBOOK

Dec. 1, 1981 - Feb. 28, 1982

PART I - OVERVIEW

The COSE III Project is a continuation of an ongoing study

conducted by Colorado State University to study the characteristics

of clouds in the Northern Colorado River Basin and their potential

for modification. The specific objectives of the experiment are to:

I) Describe the microphysical processes governing the growth
and development of prec.ipitation in northern Colorado
orographic systems.

2) Quantitatively define the dispersion and transport of
seeding materials in complex terrain.

3) Identify atmospheric covariates (predictors) needed
for analyses of weather modification programs.

4) Establish a baseline for air quality measurements in
the Yampa Valley.

The project was conducted primarily during the months of

December 1981 and January 1982, in Steamboat Springs, Colorado.

Additional measurements were conducted on some days in February 1982.

The following is a list of the instrumentation utilized during the

project:

1) Aircraft: Cheyenne II:: Colorado International Corp.
WP3D: National Oceanic and Atmospheric Admin.
Seeder Aircraft: Colorado International Corp.
Cessna N9l025: Colorado State University
Ultra-lite: Colorado State University

2) Remote Sensing: K-Band radar: National Oceanic and Atmos.
Admin.
