II. Equipment and Facilities
The following will be utilized to accomplish the objectives
during the 1985-86 field effort:

A. Microwave Radiometer
The Bureau of Reclamation microwave radiometer is an
important and relatively new instrumentation system
which can detect the presence and integrated amount of
liquid water along its 2.5 degree field of view. It is
a passive system monitoring incoming natural radiation
at 20.6 GHz (1.45cm) and 31.6 GHz (.95cm). It provides
no ranging information so interpretation of location of
the vapor and liquid must be inferred from other data
sources. The data are recorded on floppy discs and
transferred to the P-E computer via magnetic tape. Near
real-time data will be available through the Bureau's
PROBE (f.ortab 1 e B..E!rnote OBservat ions of the Invi ronrnent)
system, described later.

The radiometer will again be located at the Island Lake
site. A location on the top of Grand Mesa is probably
superior to the Island Lake site for radiometer obser-
vations. The only practical ontop site would be at the
GMO where the powerline ends (see Figure 2). However,
large equipment cannot be transported to or from the GMO
after significant snowfall covers the road. The
necessity to share the Bureau's sole microwave
