Automated Weather Observing System


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, locations airfields require some compromises, such as obstacle-free zones on the runway - navigation equipment and buildings limit the number of feasible sites. Typically, however, an airfield is so large open area at which WMO recommendations for a good spot metering Weather with surfaces free of obstacles, eventually apply. For the location of the sensors Low Level Wind shear (wind gradient) Alert System - Alert of Wind Turbulence at Low Level - always consults the

NCAR. The performance LLWAS is directly related to the accuracy of the sensor network measurement, network coverage, and geometry. Therefore, it is required an analysis and thorough research of the exact location of the sensor locations where measurements of heights and potential obstacles, should be evaluated. 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).
