Measures and reports weather conditions for aviation applications. AWOS are installed in a variety of locations, including commercial and private airports, military air bases, and heliports.


Automated Weather Observing Systems (AWOS) are the most advanced of their kind in the world. AWOS is a suite of weather sensors, which measure, collect and disseminate weather data to help meteorologists, pilots and flight dispatchers prepare and monitor weather forecasts, plan flight routes, and provide necessary information for correct takeoffs and landings.


 The data is all collected and processed in the weather room at either a PC or a server (depending on the scale of data distribution). The data is then sent to one or several display devices, other PCs, a LAN/WAN, and a voice output for broadcast.


A typical AWOS consists of the following Field Meteorological Sensors:

  •          Wind speed and direction
  •          Barometric pressure (altimeter setting)
  •          Dew point (relative humidity)
  •          Air temperature
  •          Visibility
  •          Cloud height
  •          Precipitation amount and identification (present weather)
  •          Freezing rain
  •          Lightning detection (thunderstorm)
  •          RVR (Runway Visual Range)
  •          Ambient light
  •          Runway light intensity monitor (RLIM)
  •          Solar radiation
  •          Runway surface condition
