The WMO Publication No. 8 (Guide to Meteorological Instruments and Methods of Observation), suggests multiple guidelines for site selection, sensor measurement techniques and calculation of measurement data.
One of the rules states that a "station aeronautical meteorological observatory, should make observations that describe the specific conditions of the local airfield".
Where the measuring stations are used for various purposes, the most limited condition will dictate the precise location of the sensor.
Generally, locationsairfieldsrequiresome compromises, such as obstacle-free zones on the runway-navigation equipmentand buildingslimit the number offeasiblesites.

More detailed instructions and guidelines for selecting the location of the meteorological equipment at the airport, are published in ICAO - ICAO Aeronautical Practice Manual, Fourth Edition - 1993 (Doc 8896-AN/893/4).
