Dallas/Fort Worth CASARADAR TEST BED
CASA Motivation
2
NEXRAD coverage at 3 km (10,000 ft) AGL.
NEXRAD coverage at 1 km (~3200 ft) AGL.
• Dense networks of low power, dual pol, multi-Doppler, X-band radars• High spatial and temporal resolution• Adaptive scans based on weather, user needs and radar capabilities

CASA’s Solution
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 Dallas-Fort 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
7
• Rapid, High Res. “smart” scans – balance competing user needs for data– adapt to changing weather– RHIs, PPIs, dual Doppler, sector scans, within a volume scan
• Improved resolution, sensitivity, accuracy, and ability to support multiple users and multiple applications.
NEXRAD = 5 min between updates
CASA = 1 min between updates

Timeline
• May 2011 NCTCOG Approves Feasibility MOU with CASA
• June 2011 CASA WX Steering Committee
• August 2011 CASA WX Funding Subcommittee
• September 2011 NWS Funds $500K toward DFW Testbed Demonstration Projects
Timeline Continues
• October 2011 Commence relocation of Oklahoma test bed to DFW area
• November 2011 Finalize initial sites• February 2012 Complete installation of initial four
radar network• March 2012 Demonstration network operational • June 2012 Finalize second round of radar sites• October 2012 Complete installation of second round
of radars
PROPOSED RADAR LAYOUT
FIRST FOUR SITES:Site 7: UNT Discovery Park, DentonSite 3: Alliance Airport, FAA buildingSite 11: University of Texas, ArlingtonSite 2: TBD – Carrollton, near G. Bush Tpk. And Kelly BlvdBlue – submitted sitesGreen, Yellow : new sites
NEXT FOUR SITESSite 5: Terrell Municipal AirportSite 9: Mesquite Metro AirportSite 13: McKinney Public Safety BuildingSite 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 AreaAdd 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
