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
