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

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

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, sv)
• 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, sv)

The Community in CAPRIS A Development
Partnership

• Institutional Collaboration (24 people from gt6
  groups)
• Scientific and Technical Collaboration (20
  people from gt15 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

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 RD and collaboration
