b) runway visual range, when all changes of one or more steps on the reporting scale in use are being reported to the local air traffic services unit by an observer on the aerodrome. Local special reports shall also be made available to the operators and to other users at the aerodrome. 4. OBSERVING AND REPORTING OF METEOROLOGICAL ELEMENTS Introductory Note.— Selected criteria applicable to meteorological information referred to under 4.1 to 4.8 for inclusion in aerodrome reports are given in tabular form at Attachment D. 4.1 Surface wind 4.1.1 Siting 4.1.1.1 Recommendation.— Surface wind should be observed at a height of approximately 10 m (30 ft) above the runway(s). 4.1.1.2 Recommendation.— Representative surface wind observations should be obtained by the use of sensors appropriately sited. Sensors for surface wind observations for local routine and special reports should be sited to give the best practicable indication of conditions along the runway and touchdown zones. At aerodromes where topography or prevalent weather conditions cause significant differences in surface wind at various sections of the runway, additional sensors should be provided. Note.— Since, in practice, the surface wind cannot be measured directly on the runway, surface wind observations for take-off and landing are expected to be the best practicable indication of the winds which an aircraft will encounter during take-off and landing. 4.1.2 Displays 4.1.2.1 Surface wind displays relating to each sensor shall be located in the meteorological station with corresponding displays in the appropriate air traffic services units. The displays in the meteorological station and in the air traffic services units shall relate to the same sensors, and where separate sensors are required as specified in 4.1.1.2, the displays shall be clearly marked to identify the runway and section of runway monitored by each sensor. 4.1.2.2 Recommendation.— The mean values of, and significant variations in, the surface wind direction and speed for each sensor should be derived and displayed by automated equipment. 4.1.3 Averaging 4.1.3.1 The averaging period for surface wind observations shall be:
