AUTOMATED WEATHER OBSERVING SYSTEM (AWOS)

Automated weather observing system (awos) is another type of an automated weather station. it is sophisticated and is designed to provide the necessary information to generate weather forecasts. It serves as the primary climatology observing network.

AWOS data typically includes ceiling and sky conditions, visibility, temperature, dew point, altimeter setting and wind speed, gusts and direction.

For aviation and meteorological operation we provide automated weather observation systems. The aviation weather system reports real-time information to the traffic control, pilot, and airport-related information. Measuring the more complex observed parameters of environment condition, visibility with the latest technology, and improved processing and data collection system. AWOS more data received in a timely and continuous in all atmospheric conditions and meeting your requirements and the requirements of your end-users.

AWOS Measurements

  • Barometric pressure, altimeter setting and density altitude
  • Wind speed and wind gusts, wind direction and variable wind direction
  • Temperature and dew point
  • Visibility and variable visibility
  • Sky condition, cloud ceiling height and liquid precipitation accumulation
  • Precipitation type (e.g. rain, snow, drizzle) identification
  • Thunderstorm detection by means of a cloud-to-ground lightning detector
  • Freezing rain detection via a freezing rain sensor
  • Visibilidad vertical
  • Runway surface conditions

Weather Data Dissemination

Our AWOS systems disseminate weather data in a variety of ways:

  • A computer-generated voice message which is broadcast via radio frequency to pilots in the vicinity of an airport. The message is updated at least once per minute, and this is the only mandatory form of weather reporting for an AWOS.
  • Optionally, a computer-generated voice message, available over a telephone dial-up modem service. The message is updated at least once per minute.

Optionally (but frequently done), AWOS messages may be disseminated via ground data link in METAR format, typically once every 30 minutes.

Components of Weather Station for the Automated Weather Observation System:

Anemometer– Measures wind direction and speed.

Thermometer – Measures atmospheric temperature.

Pyranometer – Measures solar radiation levels from the sun in watts per square meter (used to calculate ‘Evapotranspiration’, the rate at which water evaporates from the soil).

Hygrometer – Measures relative humidity using a percentage measure of water vapor in the air.

Barometer – Measures atmospheric pressure to predict precipitation and visibility.
