  10. Digital Aviation Forecasts in NDFDWhy so slow? • FAA writes the rules. Following systems must be ready to accept new products: • AFSS Model I • AFSS OASIS • DUATs • WARP • ADDS • Traffic Situation Displays • Training Across the Board

  11. Digital Aviation Forecasts in NDFDWhy so slow? • All of the players involved: • NWS • FAA • Flight Standards (Regulations, transmission, pilot training) • Air Traffic (ARTCC, ATCSCC, TRACON) • Flight Service Stations • DUATs • Aviation Organizations (AOPA, ALPA, ATA, SAMA, ADF) • International Conventions (ICAO, WAFS, MSC)

  12. Digital, Gridded Data RequirementsWhy Aviation is Different • Time Resolution • Vertical Resolution • Weather Type • Cloud coverage or “cloud/no cloud” • Probability (in next 10 minutes?)

  13. Digital Aviation Requirements • Ceiling and Visibility every 15 minutes • Graphic shows Airport Arrival plan which is adjusted based on forecast.

  14. Digital Aviation Requirements • Wind direction and speed, every 5 minutes. • Graphic shows planes lined up to land at O’Hare and Midway based on current runway configuration. Jan.20, 2003: 1730 UTC ORD & MDW Arrivals

  15. Digital Aviation Requirements • In convection, every 10 minutes for the first hour. Mitre Corporation Automation-assisted Weather Problem Resolution Tool

  16. Time Resolution Hours 0-3: 15 minutes Hours 3-24: 1 hour Updates every 15 minutes. Vertical Resolution Surface-1,000 AGL: Every 100 feet 1,000-3,000 feet: Every 200 feet 3,000 feet to FL650: Every 1,000 feet Horizontal Resolution 2.5 km NWS Integrated Work Team looking at very short term aviation forecasts in a post IFPS/NDFD environment Future Domestic Requirements Gridded Data (Draft)

  17. In the Meantime… What digital products exist or are being developed today?

  18. GRIB File BUFR File National Convective Weather Forecast (NCWF) Every Five Minutes!!!

  23. Graphical Area Forecast (GFA)

  24. Graphical Area Forecast (GFA) • Replace current text Area Forecast as main product. • Text provided through product formatters • Using GAMET format • GFA replace hours 9-24 of non-international TAFs. • Assumes higher TAF refresh rate 0-9 hours. • Issued in BUFR format

  25. Graphical Area Forecast (GFA) • BUFR • Earth referenced ‘objects’. Not gridded. • Meets WMO/ICAO standard for earth-referenced objects. • Allows display of individual features at user discretion. • Much lower traffic volume. • Requires user to ‘build’ product at destination. • Already being done in the World Area Forecast System (WAFS)

  26. Graphical Area Forecast Experiment(GFAX) • Graphical Area Forecasts on experimental basis being prepared at AWC January 13-February 14. • Purpose • Identify the production tools required. • Allow users to provide input on presentation. • Produce products to help develop text formatters.
