Modernization of the automated weather observation system (AWOS) at Sofia atc centre
The Automated Weather Observation System (AWOS) at Sofia AТC Centre is designed to measure, process, visualize, disseminate and provide meteorological information, representative of Sofia aerodrome area, for the needs of the aircraft crews departing from or arriving to Sofia airport, ATS units, aerodrome meteorological services and aviation operators.
A project for Modernization of the Automated Weather Observation System (AWOS) at Sofia ATC Centre is forthcoming to be implemented in 2017. The scope of the project includes replacement of part of the sensors with new ones – the latest model of scatter meter and an automatic MET station offered by company VAISALA. The AWOS software along with the servers which approach the end of their life cycle also will be replaced. The new version of the AWOS software shall enable the reporting of vertical visibility and cloud-base with 15ft accuracy. These activities shall improve the accuracy of measurement and reporting the cloud-base or vertical visibility, which shall contribute to the improvement of flight safety in Sofia terminal area in the conditions of low visibility.
