Aviation Weather Decision Support System
In order to provide the air traffic controllers and meteorologists with the accurate operational information the IMS4 AWDSS processes the real-time data from various sources: local AWOS, ARWIS and LLWAS systems, weather radars, surface observations from the WMO/ICAO exchange networks, meteorological satellites, profilers, etc.


  • Detection, nowcast and forecast of phenomena affecting the airport operation
  • Data integration from multiple sources
  • Detection and nowcasting algorithms and forecasting models:
    • Thunderstorm
    • Low level windshear and microburst
    • Gust fronts
    • Turbulence
    • Fog
    • NWP models

The collaborative, net-centric and combined picture incorporating seamlessly all aviation relevant weather sources will enable various users at the airport to have access to all relevant information needed for tactical decision support during the flight phases:

  • Take off
  • Departure
  • Metering/descent
  • Final approach
  • Landing
Having employed the state-of-the-art algorithms and models, the system evaluates the general situation, area, airport specific and runway oriented alerts, using the color status signalization to visualize the hazards, if any.

The current as well as anticipated operational situation may be characterized by the alerts of the hazardous phenomena, current/anticipated airport/runway operational category, NATO color code or in the other way compliant with the operational procedures of the particular airport.
