The Automated weather Observing System (AWOS) measures all of the weather parameters at airport facilities, airfields, heliports, etc., providing the processed data to the ATC and Meteorological Office, which distributes it in different ways to the aircraft pilots and the air traffic safety authorities.
Which parameters are measured will depend on the category of each airport; the following are the most important and commonly measured values:
Wind Speed and Direction
Relative Humidity of the Air
Atmospheric Pressure (QFE-QNH)
Visibility (MOR- Meteorological Optical Range)
Present Weather (intensity and type of precipitation: rain, snow, hail, etc.)
Turbulence at Altitude
In addition to these parameters, the AWOS system can take other useful measurements to provide information on the condition of runways, as it can be the case of the presence of ice. It is also possible to measure in real time the noise level generated by aircrafts by means of our Noise Mapper System.
