  1. ADDS TMU Weather Needs Volcanic Ash Coordination Tool Advanced Convective Tool Lynn Sherretz, NOAA FSL FPAW Forum 22 October 2002 Progress in Ground-based Dissemination

  2. ADDS Funded by: FAA Aviation Weather Research Program Built by: FAA PDT for Aviation Forecasts and Quality Assessment FPAW Forum 23 October 2002

  3. No matter how much utility ADDS has to aviation operations…... …...our job will not be done until ADDS is “owned” by NWS and supported 24/7 New URL: adds.aviationweather.gov

  4. ADDS Ops Implementation • Top priority for FY 03 • Target Date: July 2003 • Agreement with NWS calls for ops&exp versions FPAW Forum 23 October 2002

  5. Ops Version of ADDS • Supported 24/7 by AWC • All functions and “look and feel” of current ADDS --but no exp products • Conforms to FAA criteria for Internet providers • Enhancements may require formal notice FPAW Forum 23 October 2002

  6. Exp Version of ADDS • Supported 8/5 by AF&QA PDT • Has all that ops version has--enables comparing exp products with ops products • Not required to conform to FAA Internet criteria • Has exp products and viewing tools • Enhancements announced via home page FPAW Forum 23 October 2002

  7. Recent Comments • “ADDS is an example of government at its best.” • “Frankly, I thought I’d never say this about any Web service from the government. The Java tools are incredible. I am completely stunned.” FPAW Forum 23 October 2002

  8. Tailoring and Evaluating Advanced Convective Products for FAA Traffic Managers Our work responds to requirements based on identified needs Decision-Based Weather Needs for Air Route Traffic Control Center Traffic Management Unit November 1999

  9. Objectives • Tailor (from existing products & research) graphics that support strategic decisions • Consolidate critical information from automated and human-generated forecasts • Assess met validity and ops utility via RTVS FPAW Forum 23 October 2002

  10. High-level Goal Convective SIGMET Convective SIGMET Outlook CWA & MIS TCWF & RCWF CCFP-1 Present NCWF-1 CWA Tactical Convective Forecast Strategic Convective Forecast Future 0 hrs 1 hr 4 hrs 6 hrs 2 hrs FPAW Forum 23 October 2002

  11. Concept for Initial Strategic Product Consolidate NCWD/NCWF and Convective SIGMETs Advect C-SIG polygon with NCWF FPAW Forum 23 October 2002

  12. Volcanic Ash Coordination Tool: Test/Evaluate for Alaska

  13. Proposal to FAA • Use FSL’s FX-C workstation to enable….. • Anchorage ARTCC CWSU • AAWU Volcanic Ash Advisory Center • Alaska Volcano Observatory • …..to collaborate in real-time (viewing identical data) to generate time-critical advisories for ash. FPAW Forum 23 October 2002

  14. Aviation Operations Problem More than 200 flights cross North Pacific each day….. …...and 100 active volcanoes may emit ash in that airspace. Ash/aircraft = sodium/water FPAW Forum 23 October 2002

  15. Advanced Convective Tool (ACT) Explore concepts for AWC to generate 0-6 hr gridded probabilistic convective fcsts based on automation&forecaster input. Explore utility to aviation end users--subjectively and objectively via RTVS. FPAW Forum 23 October 2002

  16. Advanced Convective Tool (ACT) • Develop/test concepts for AWC to generate 0-6 hr seamless probabilistic gridded fcsts of convection based on automation&forecaster input. • Explore utility of probability forecasts to aviation end users--subjectively & objectively via RTVS. FPAW Forum 23 October 2002

  17. Why Probabilistic Forecasts • Accurate explicit forecasts are not possible now. • Current CCFP has a “probabilistic” component. • Some users want NWS fcsts to include “confidence.” • Enable FAA traffic mgrs (in concert with air carriers) to “manage” risk based on ops costs.
