(d)
Maximum and minimum thermometers were mounted in the shelter in the
standard manner (on the cross-beam, just forward of the back of the shelter, facing
the door).
These were Standard Weather Bureau instruments:
mercury-in-glass and
alcohol-in-glass.
(e)
A standard hygrothermograph was kept in the shelter.
This was a Friez
recording instrument, with a 7-day setting (7-day chart), and with a hair-and-lever
mechanism for recording relative humidity.
(f)
Direct dry-bulb and wet-bulb temperature readings were made using a Friez
psychron (mercury-in-glass thermometers graduated in whole-degrees Fahrenheit and
mounted in a unit with a battery-driven fan).
The psychron was placed in the shelter
and the reading was made at the time of lowest wet-bulb reading.
Site Description;
Figures 11 and 13 show the location of instruments on KEITH and
Plate II shows views of these instruments.
These figures and the photographs in the
Plate give detailed information as to the nature and distribution of ground cover and
as to topography.
The ground was barren beneath the shelter, anemometer, and rain-
gage, and consisted of beach-rock covered by a thin veneer of coralline sand and
gravel.
Instruments:
The instruments used were identical with those for BRUCE (above).
Figures 11
and 13 and Plate II provide information concerning instrument exposure.
ELMER
Site Description:
Observations were made at two different sites.
Through February
28, 1958, observations were made near the northeastern end of ELMEh, with the raingage
and the shelter in a large open area lying between a tank farm (to the NE) and quonset
huts (to the SW)e
Effective March lst, rainfall observations were taken near the
dispatchers shack at the airstrip toward the SW side of EIMER.
At both sites, the
instruments were well out in the open and were underlain by barren ground consisting
of coralline sand and gravel.
Shelter and raingage locations with reference to
buildings are shown in Figure 8.
Instruments:
