  1. Planning for DWL Airborne Demonstration - Discussion Ken Miller Lidar Working Group Monterey CA February 7, 2008

  2. Topics • Discuss airborne mission possibilities • Capabilities needing demonstration • Approximate schedule • Campaign opportunities

  3. Airborne Objectives • Advance instrument TRLs • Performance and functionality • Robustness and reliability • Demonstrate technology for space mission • DD & Coherent subsystems and components • Hybrid DWL data • Down-looking • High altitudes • Validate atmosphere and instrument models • Signal processing

  4. Airborne Objectives 2 • Demonstrate technology • Optics • Separate for Coherent and Direct Detection • HOE for Direct Detection • Scanners (Step-stare, not multiple fixed apertures) • Calibration and Validation • Cross-validation of DD & Coherent • Other instruments and models • Overfly ground instruments • Underfly satellites

  5. Airborne Objectives 3 • Science Campaigns • Hurricane Genesis Mission 2010 • Forecast impacts • Hurricane studies • Future Operational Use: hurricanes, winter storms?

  6. Status • Recent NASA planning decisions • Provides some direction • Includes • WB-57 flights for TWiLiTE • DC-8 hybrid shirtsleeves flight • Funded • TWiLiTE DC-8 accommodation, flight test? • DAWN DC-8 readiness, flight test?

  7. Status 2 • Planned – Hybrid DC-8 • Engineering flights • Hurricane Genesis Mission 2010 • Beyond current planning • WB-57 TWiLiTE campaigns • DC-8 hybrid other than Hurricane Genesis • WB-57 autonomous hybrid capability and high altitude flights • UAV flight

  8. GWOS (2016) Shirtsleeves Hybrid DC-8 Hurricane Mission Summer 10 AutonomousHybrid, WB-57 2012 ? Roadmap to Operational DWLon Nex-Gen NPOESS Nex-Gen NPOESS (2026) Operational 3-D global wind measurements ESA ADM (2009) ADM DD & Coh Winter 08 Demo 3-D global wind measurements TODWL & Airborne Demo (2002 ----) Single LOS global wind measurements DWL Airborne Campaigns, ADM Simulator, etc. TWiLiTE WB-57 Summer 09

  9. NASA Chart

  10. Direct Detection Solo

  11. Hybrid Shirtsleeves DC-8

  12. Hybrid Autonomous WB-57

  13. Variations • Sources of funding for measurement campaigns • UAV – Global Hawk • Joint flights with other lidars

  14. Airborne Shared Optics Unlikely • Aircraft • Not needed? • Would limit flexibility • Shared optics in GWOS Space demonstration

  15. Preliminary Time Line • TWiLiTE Solo • Test Flights • WB-57 Flights • UAV • Hybrid • Shirtsleeves, Hurricane Mission, DC-8 • Autonomous WB-57 • CAMEX 6 • Hurricane Genesis Mission 2008 2009 2010 2011 2012
