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

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

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

6. 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. 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
