What is CASA?
• National Science Foundation Engineering
Research Center
– Academic, Government and Private Sector Partners
– NOAA is a CASA partner
• Developing new weather observation systems
based on low-power, low-cost networks of
radars.
• Transition research to operations.
• Year 8 of a 10-year research project
Purpose: Establish a radar network in the DallasFort Worth area using CASA technology.
• Comprehensive radar data in the lower
atmosphere
• Faster radar return rate
• Higher resolution
– Flood and Wind (thunderstorm, tornado) forecasts
– Flood and Wind decision support tools
– Base level radar data
• Public/Private Partnership
NEXRAD = 5 min between updates
CASA = 1 min between updates
•
Rapid, High Res. “smart” scans
•
Improved resolution, sensitivity, accuracy, and ability to support multiple users
and multiple applications.
– balance competing user needs for data
– adapt to changing weather
– RHIs, PPIs, dual Doppler, sector scans, within a volume scan

PROPOSED RADAR LAYOUT
FIRST FOUR SITES:
Site 7: UNT Discovery Park, Denton
Site 3: Alliance Airport, FAA building
Site 11: University of Texas, Arlington
Site 2: TBD – Carrollton, near G. Bush Tpk. And Kelly Blvd
Blue – submitted sites
Green, Yellow : new sites
NEXT FOUR SITES
Site 5: Terrell Municipal Airport
Site 9: Mesquite Metro Airport
Site 13: McKinney Public Safety Building
Site 3: TBD - Near Farm to Market Rd. 2755 and County Rd. 536
Option #1: Expand to South West as one continuous network
TOTAL NETWORK SIZE = 12 RADARS
Option #2: Expand to SW as two disjoint networks
TOTAL NETWORK SIZE = 12 RADARS
Plan for Covering the Whole COG Area
Add 3 radars to connect the disjoint networks.
Add 3 radars to expand in South East direction.
Add 2 radars to expand in North East direction (including Commerce High School
and one new site TBD at Merit, near Farm to Market Rd. 36 and County Rd. 1126)
TOTAL NETWORK SIZE = 20 RADARS
Proposed Demonstration Projects
• Public Response to Severe Weather Warnings
• Neighborhood-based Flash Flood Warnings
• Development of Impacts-based Weather
Information
• Emergency Management Training
