CASA’s North Texas Urban Aviation Weather Testbed

Apoorva Bajaj, Brenda Philips (CASA Engineering Research Center) Ernest Huffman, Molly McFadden (North Central Texas Council of Governments) September 3, 2020

This research supported through NSF award numbers 1700967 and 1632193.

NEXRAD coverage at 1 km (~3200 ft) AGL.

Addressing an important weather observation gap

E.g. Radar height at McKinney, 60 miles from KFWD is 1 mile AGL. 72% of atmosphere <10,000 ft goes undersampled CASA radars (blue) fill the gaps.

CASA DFW Living Lab for Severe Weather Warning Systems

❑ Sensors-to-People Real-Time

Severe Weather Warning System covers 7+ million people

❑ Centered around X-band CASA

radars & other sensors

❑ Multidisciplinary research in live

environment (physical, technical, social/behavioral sciences)

❑ Co-Creation and technology

transfer with users through a public private partnership

CASA network covers approximately 32,000 sq. km. Radar range is 40 – 100km. Overlapping coverage improves data quality

SENSORS PRODUCTS/ DISPLAY USERS

Public-private partnership with North Central Texas cities, National Weather Service for installation and operations of radar network.

• 10 year agreement with North

Central Texas Council of Governments

• Deep rooted community

connections (EMs across 50 cities in N. Texas, Public)

• Data used by National Weather

Service and DFW Airport.

• NASA SIO Weather Avoidance

partner for Bell

• NCTCOG UAS Task Force

On-Going Research: High Resolution Rainfall data

QPE System Blends X- and S-Band Radars

Ongoing Research: Multi-Organizational Coordination & Public Response

Benefits of Urban Scale Data: NWS, EMs, Stormwater

Why establish an ‘Urban Aviation Weather Testbed’ in North Texas?

❑ Region is motivated, lots of UAS/UAM stakeholders ❑ Growing number of public safety and commercial operators ❑ Mix of urban and rural flying environments ❑ Interesting weather throughput the year ❑ Lots of weather sensors; but also lots of sensing gaps! ❑ Large research community ❑ Builds on CASA’s existing urban severe weather testbed

• Infrastructure, products, stakeholder relationships

Growing usage of drones in North Texas for public safety

May 2015: Support for flood rescue June 2019: Dallas crane collapse

• Hazardous weather response
• Search and rescue, accident response
• Structure and brush fires
• SWAT missions

• Hail damage inspection
• Bridge inspections
• Solar panel inspections
• Railway/ airport surveillance

“Rain will ruin photos/ videos.” “Tell me if rain fell in the last 24 hours; if surfaces are wet (roof/ solar panel inspections).”
