Locating the ISS and Anemometer
For the weather station to perform at its best, use these guidelines to select the optimum
mounting locations for the ISS and anemometer. Be sure to take into consideration ease
of access for maintenance, sensor cable lengths and wireless transmission range when
siting the station.
Note: When selecting a location for installing your ISS, especially on a rooftop, make sure it is a location
far from power lines. Seek professional help if you uncertain about the safety of your installation.
General ISS Siting Guidelines
• Place the ISS away from sources of heat such as chimneys, heaters, air conditioners
and exhaust vents.
• Place the ISS at least 100' (30 m) away from any asphalt or concrete roadway that
readily absorbs and radiates heat in the sun. Avoid installations near fences or sides of
buildings that receive a lot of sun during the day.
• Ideally, place the radiation shield of the ISS 5' (1.5 m) above the ground in the middle
of gently sloping or flat, regularly mowed grassy or naturally landscaped area that
drains well when it rains. For areas with average maximum yearly snow depths over 3'
(0.9 m), mount the ISS 2' (0.6 m) above this depth.
• Never install the ISS where it will be directly sprayed by a sprinkler system because it
will adversely affect the readings.
• Avoid installations near bodies of water such as swimming pools or ponds.
• Do not locate the ISS under tree canopies or near the side of buildings that create “rain
shadows”. For heavily forested areas, site the ISS in a clearing or meadow.
• Site the ISS in a location with good sun exposure throughout the day if the ISS is
wireless or includes solar radiation or UV radiation sensors.
