Automated Weather Observing Systems (AWOS)

ITC SA is responsible for the design, configuration, programming, initial installation and maintenance of an automated Weather Observing Systems (AWOS).

An AWOS system consists of a set of meteorological sensors connected to one or more data-loggers connected to a computer with software that collects and stores the meteorological data in a database.

The work that ITC has successfully completed and within the project schedule is:

  • Development of meteorological data collection software in accordance with the requirements of the application such as compliance with the most stringent regulations defining meteorological systems for airline applications (full compliance with ICAO International Civil Aviation Organization specifications – Annex 3 Meteorological Service for International Air Navigation),
  • Database Design (based on MariaDB one of the most widely used open source databases in Linux environment), automated fault detection
  • Ergonomic design of a user-friendly interface (GUI) as well as design for seamless operation and collection of meteorological data, timely update in case of technical problems.
  • Configuration that includes configuration file setup over the Internet so that changes to settings can be performed remotely,
  • Provision for connecting to a central data collection computer system from many AWOS stations to collect past data for further processing or display.

The meteorological stations include the following individual sensors:

  • Ultrasonic wind sensor
  • Temperature – humidity sensor
  • Barometer
  • Pyranometer for solar irradiance
  • Rain gauge
  • Lighting level and visibility sensor
  • Nebulometer
  • Thunderbolt sensor
  • Airplane Light Intensity Sensor

Overall, detailed data are provided, in accordance with strict regulations (ICAO and FAA), which include, inter alia, the intensity, direction and trend of the last interval for wind, temperature, sunshine, visibility, humidity, atmospheric pressure, cloud coverage.

Stations are designed to be connected to the Internet and can send data to a Cloud Virtual Server, both for data storage and operation, increasing system flexibility.

A Cloud Database application has also been developed to collect operating data and data from an AWOS network where new stations can be easily imported and easily managed and monitored from the Internet, and all stations displayed on maps (Google maps) to make the administration environment extremely friendly and easy to use.

It is planned to install the stations in other environments in the future, such as oil platforms, while simultaneously having the ability of combining stations and their data with company-developed forecasting models and/or hindcasts, with the aim to analyze and evaluate meteorological conditions in areas of high interest.
