CHAPTER 3

SELECTING LOCATION

This chapter provides information on siting the station and the sensors

correctly.

Siting the Station

Finding a suitable site for the weather station is important for getting

representative ambient measurements. Normally, the suitable site

should represent the general area of interest. When locating the weather

station, consider the items presented in the sections for each sensor. The

descriptions are not exhaustive, for further information refer to local

and WMO recommendations.

Combined Wind Sensor

Allow sufficient clearance for the wind sensor. Install the wind sensor

away from buildings or any other objects that might affect the airflow.

In general, any object of height (h) will not remarkably disturb the wind

measurement at a minimum distance of 10 × h. There should be at least

150 m (500 ft.) open area to all directions from the mast. Refer to Figure

35 on page 50.
