Radar-Based Aviation Weather Services Mark Weber MIT Lincoln Laboratory 8 October 2003
Outline • Improved Measurements • ASR-9 Weather Systems Processor • TDWR Processor Modernization • Improved Nowcast/Forecast Services • Medium Intensity Airport Weather System • Corridor Integrated Weather System
ASR-9 Weather Systems Processor Site Status
TDWR Measurement Enhancements(Exploit New Radar Data Acquisition Processor) Suppression of Range-Overlaid Weather Echoes Range Overlaid Echoes Current Processing Enhanced Algorithms Atmospheric Moisture Fields using “Radar Refractivity” technique
Medium Intensity Airport Weather System (MIAWS) Tower/TRACON Supervisor Display SD Pull-DownMenus Storm Position 10 & 20 Minute Extrapolation Storm Motion Vector Sites Runway Arenas
Corridor Integrated Weather SystemCIWS Benefits – 2003 Summer Storm Season FAA Facilities with CIWS Prototype Command Center Regional Office ARTCC TRACON • User-Identified CIWS Benefits: Projected Times/Year • Jet routes kept open/reopened earlier > 800 • Proactive, efficient reroutes > 300 • Identification of storm over flight opportunities > 200 • Improved handling of storm impacts on > 100 • ARTCC/TRACON interface • Better use of Ground Stop/Ground Delay TBD • Programs • Greater departures during SWAP TBD • Reduced MIT restrictions TBD • Improved interfacility coordination • Reduced user workload • (traffic manager/controllers) CIWS Products Include: 0 – 2 hr Storm Forecast (looping 15min increments or contour overlay) NEXRAD/ASR-9 Precip; Storm Motion Information • Individual CIWS Delay Reduction Event: 10 July 2003 • PHL westbound routes blocked by storms • Using CIWS Echo Tops Product – 9 hr storm over flight reroute for • PHL/NYC traffic • Delay Savings ~ $ 2.1 M Satellite Data; Storm Growth/Decay Trends Echo Tops; Lightning
Summary • Ongoing progress in enhancing weather measurement capabilities of U.S. operational radar networks • FAA fielding systems that exploit these radar networks to provide high-benefit nowcast and forecast products
