Chandrasekar
Technology test bed
Work with partners to develop and evaluate
new DCAS technologies for applications
Examples:
Radiation laboratory will conduct fabrication and testing of the
antenna systems
Evaluate the polarization matching and purity of the various
NETRAD radars for DCAS application and improve design
accordingly.
Characterize the integrated side-lobe performance for predicting
performance in various terrains.
Characterize the performance of the wireless data links in intense
tropical precipitation. Study the data loss as a function of rainfall
rate.

Tropical storm/Hurricane
Testbed
Develop special DCAS operations for tropical
storm/hurricane environment.
A) Pre-landfall mode of operation, study approaching rainbands
B) During land-fall to study the complete microphysical
structure and the associated performance of DCAS,
including loss of some radars. Collaborate with Hurricane
Research Center
C) Develop and validate specific QPE algorithms tuned to
tropical storms in conjunction with in-situ sampling of the
raindrop size distribution.
D) Conduct systematic study of storm microphysics via
polarimetric radar observations for the Puerto Rico
environment .
Long-term Plan
• Expand campus testbed into island-wide
DCAS system.
• Engage National Weather Service (San
Juan)
• Integrate other end-users such as
Emergency Management and Planning,
FEMA
Visualization of radar
coverage of PR as a test-bed
