INTRODUCTION
The Colorado WDMP research project was joined with the Denver Water Department’s operational cloud seeding program in the central Colorado Rocky
Mountains for the 2003-2004 winter season.
DWD’s cloud seeding program was operated by Western
Weather Consultants, LLC - Larry Hjermstad
WWC seeding generator site V1 (Ellison),
elevation 7,088 ft, looking SE
Up to 56 ground-based seeding generators were used to release silver Iodide over a mountainous target area of about 3700 sq. km.

GOAL
To provide a physical
evaluation of the operational cloud seeding using the well-established Colorado State
University Regional
Atmospheric Modeling System
(RAMS), with a fine 3-km horizontal
grid spacing covering the entire
seeding area. RAMS 3-km grid with target area boundary, towns,
seeding generator locations, Snotel sites

OBJECTIVES
Use RAMS to develop a better understanding of the transport and dispersion of seeding materials and to
provide guidance as to what meteorological conditions are most favorable for augmenting snowfall from orographic clouds over the Colorado mountains.
