• Project Name: Sierra Cooperative Pilot Project
• Title: Sierra Cooperative Pilot Project - Operations Plan - 1986-1987
• Date: 10/1/1986
• Weather Modification - Doc Type: Report

Snow Lab (USFS) are obtained in the form of copies of original gauge charts.
These charts will be reduced using the same procedures used on the SCPP charts
in past years. In addition, two high resolution snowmass gauges will be oper-
ated by Bureau personnel to compliment the ground microphysical observations
at Kingvale. Information pertaining to these special gauges is given in table
3-6.

Data from other cooperators are received in tabular form and are entered as
hourly amounts into the SCPP data base. SMUD, DRI, PGE, and Sacramento County
provide this data. Gauge locations and elevations for these cooperator net-
works are given in tables 3-7 to 3-10. Fig. 3-9 is a map showing cooperator
gauge location relative to the ARB.

F. SURFACE METEOROLOGICAL MEASUREMENTS
Six PROBE stations will be operated during the 1986-87 field season in order
to obtain weather conditions according to the instrument sensor layout pro-
vided in Table 3-11. The stations locations are shown in fig. 3-10. Table
3-12 also lists the station identification along with other information
regarding GOES transmission.

Three new stations have been sited for the 1986-87 field season. SIG (Signal
Peak) is colocated with a microwave relay station operated by Western
Telecommunications. The site has very similar exposure to that of Squaw Peak.
SSR (Sierra Ski Ranch) is located on top of the Sierra Ski Ranch downhill ski
resort. SLM (Slide Mountain) is located in Nevada, and will be maintained by
the Desert Research Institute.

The point of contact for access to SIG will be Mr. David Jarvinen of Western
Telecommunications, Inc. (Sacramento 447-7708). Access to station SSR can be
coordinated through Mr. Vern Sprock of Sierra Ski Ranch (659-7453).
