and all personnel were returned to inhabited areas prior to nightfall.
Personnel who operate motor vehicles are given instruction In safe
operation of loaded vehicles under snowpacked roadway conditions
normally encountered during wintertime.

The capablllty of WSSI to perfonn In the field Is demonstrated by the
amount and quality of meteorological data collected, processed, and
avallable from the pilot project measurement sites. During the 1971-
72 winter season, the 55 recording precipitation gages (seven
additional gages were installed for the 1972-73 season) 1n the plIot
project's instrumentation network recorded 9 8.6 percent of the com-
bined total hours of possible detailed hourly data.

2.1.7 Special Field StudY - During the 1972-73 winter season, WSSI
personnel are collecting additional meteorological data on approximately
30 to 35 experimental days over a five-month period. These data are
being collected in the vicinity of Wolf Creek Pass. Observations of
meteorological parameters made by (1) radar, (2) rawinsonde, (3) ice
nucleus counters, (4) Ice crystal repIlcators, and (5) visual methods
are being used for the dual purpose of supplying real-time informatton
to the seeding contractor and for post analyses of the experimental days.
All data are being collected without prior knowledge of whether an
experimental "seed" day or an experimental "no seed" day has been
called by the seeding contractor. The primary observation site consists
of 3 cm RHI and PPI radars and a RD-65 rawinsonde unit.
