  1. Community Airborne Platform Remote-sensing Interdisciplinary Suite MPAR Working Group Meeting Office of the Federal Coordinator for Meteorology NCAR Earth Observing Laboratory James Moore, Wen-Chau Lee, J. Vivekanandan, Eric Loew, Scot Spuler, www.eol.ucar.edu/developments/capris

  2. CAPRIS Research Highlights • Addressing Mesoscale processes • TC research and forecasting • Measuring Aerosol and Cloud Structure • BL and full depth structure and tracking • Climate Change Components (e.g. clouds, • Precipitation, water vapor, aeorsols) • Impacts local , regional and global • Data assimilation and model validation

  3. CAPRIS Technology Highlights • Eye safe Lidars • Phased array CM radar • World class aircraft platforms • Real-time Data processing and display • Processed data satellite relay to the ground • Ground based deployment

  4. The NSF Opportunity • Mid-Size Infrastructure for Atmospheric Sciences • ATM maintains a mid-size infrastructure account that can be used to build and/or acquire community facilities. • Several groups will be competing for available funds • General Considerations (highlights) • Community facility • Available funds for larger projects • Instrumentation and observing platforms are eligible • Partnerships with university, federal, private, or international institutions are encouraged. • EOL has been encouraged to submit a White-paper for CAPRIS • Key time for community comment and advice on present concepts • Revised White Paper Document due to NSF Mid March 2007 • NSF ‘go-ahead’ decision for full proposal expected in summer 2007 • NSF funding decision anticipated in fall 2007

  5. Community Airborne Platform Remote-sensing Interdisciplinary Suite (CAPRIS)

  6. Examples of Combined Measurements Cai et al. (2006)

  7. CAPRIS Configurations -- Airborne CM-Radar • Four active element scanning array (AESA) conformal antennas • C band side-looking • X band top, bottom looking • Dual Doppler (V, σv) • 4 x resolution of current system due to simultaneous fore and aft beams from all four antennas • Dual polarization H,V linear • ZH, ZDR, KDP, LDR, RHOHV MM-Radar • Dual polarization H,V linear • ZH, ZDR, KDP, LDR, RHOHV • Dual wavelength (W,Ka) • Pod-based scanning • Doppler (V, σv)

  8. Possible CAPRIS Radar Positions on C-130 Upper AESA W, Ka band Pod Starboard AESA Port AESA Lower AESA C-130 front view

  9. Composite Surveillance Scan for C-130 using CAPRIS CM radar and Onboard Weather Surveillance radar Port AESA Top AESA Rear Ramp AESA WXR 700 C Weather Avoidance Radar Starboard AESA

  10. HIAPER Cloud Radar (HCR) Position in the Pod on the GV

  11. General Locations of AESA antenna beams (blue tint), MM radar Beams (green tint) and Lidar beams (purple) on NCAR C-130 Aircraft

  12. The ‘Community’ in CAPRIS A Development Partnership • Institutional Collaboration (24 people from >6 groups) • Scientific and Technical Collaboration (20 people from >15 Educational Institutions) • Town Hall Meetings at Major Conferences (ERAD, AGU, AMS • Special Visit to institutions for seminars • Special Focus Round tables (Mesoscale and Biogeosciences • Seminars adjunct to Project Workshops • International Exchange (e.g. ICMCS, Taiwan, Japan, Germany)

  13. Three Major AESA Options • X-band dual-pol, alternating H,V transmit/receive • C-band dual-pol, simultaneous H,V transmit/receive • Wide-band (X,C) dual-pol, simultaneous H,V transmit/receive

  14. Technical Characteristics AESA Airborne Configurations

  15. Some Final Thoughts on CAPRIS • Community resource for addressing key science questions • Airborne and ground based deployment options • Radar and lidar components • Community input to design requirements • Seeking collaboration with community, agencies and industry • Active testbed for R&D and collaboration
