Model “PRO”- Weather Station
Cozz GT27145B
(a) TEMPERATURE AND
RELATIVE HUMIDITY:
Sensors should be located over an open
level turf area at least 30 feet in
diameter. The surface should be the
typical turfgrass of the area in interest.
Sensors should be located a distance
away of at least four (4) times the height
of any nearby obstruction and at least 90
feet from large paved areas. Sensors
should be protected from thermal
radiation, and adequately ventilated.
Situations to avoid include:
• large industrial heat sources
• rooftops
• steep slopes
• sheltered hollows
• high vegetation
• shaded areas
• top of a hill
• bottom of a swale
• swamps
• areas where snow drifts occur
• low places holding standing
water
(b) SOLAR RADIATION:
Pyranometers should be located to avoid
shadows on the sensor at any time.
Mounting it on the southern most portion
(northern hemisphere) of the weather
station will minimize the chance of
shading from other weather station
structures. Reflective surfaces and
sources of artificial radiation should be
avoided. The height at which the sensor
is mounted is not critical.
(c ) PRECIPITATION
