2CAPRIS 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
3CAPRIS 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
4The 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

7CAPRIS 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)

12The 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)
13Three 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

15Some 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
