Projects IP1, IP2, IP3

Rain mapping, distributed hydro. modeling, flood predicting & response in urban zone.

IP2

Rain, Urban Flooding

(Houston)

Wind, storm prediction

(Oklahoma)

IP3

Rain, mountainous terrain

Project IP1 - Initial 4-Node Test Bed

  • Annual storm climatology for 7,000 sq km test bed region:

    • 4 tornado warnings (2 touchdowns)

    • 50 thunderstorms


Presented by sandra cruz pol professor electrical and computer engineering uprm casa pi

User Driven System Design

  • Users: NWS Forecast Office, Emergency Managers, & atmospheric scientists will use the Oklahoma test bed

  • Severe weather [severe thunder storms, hail, and tornados] impacts 90% of EMs in Oklahoma.

  • Tornado Pinpointing cited by EMs as important for managing deployment and protection of first responders.

  • Tornado Anticipation cited by NWS and EMs as most important for increasing lead time.

  • All users cited morefrequent updates of radar data as a critical need.

  • There is a need for lower troposphere, high resolution data for detecting: convergence lines, gust fronts, straight line winds.

Sources: Structured surveys (N=72) of Oklahoma Emergency Managers; In-Depth Interviews (N=37) of EMs and NWS using snowball sampling and content analysis to extract information; test bed user group.

Tour of the IP1 Sites

  • Avg. Separation 25.3 km

  • Coverage 6947 km2

  • 98% coverage below NEXRAD

  • 41% coverage is dual-Doppler (2850 km2)

  • 25% coverage below 250 m

  • Avg. AGL NetRad – 364 m

  • Avg. AGL NEXRAD – 1000 m


Where are we now

NetRad – prototype

Where are we now?

  • IP1 Project: End-to-End DCAS network of 4 rapid scan radar nodes.

  • 2 pol magnetron Radars cost $200k in parts; replacement cost insurance coverage was $1.5 M for 4 radars during shipment to OK.

  • Custom towers & tower-top positions to host radars.

  • Infrastructure:

    • Weight: 1,500#

    • Site: tower top

    • HVAC, radome

    • Ethernet, fiber, 802.11 access to node

    • Software: closed-loop, MC&C, policy mechanism but no decision-based policy as yet.

Est. $500k to buy & install these radars

… saving lives/property, reducing vulnerability, providing economic benefits through improved warning and response to hazards

… diverse education, outreach

… industrial opportunities, commercial development


Presented by sandra cruz pol professor electrical and computer engineering uprm casa pi
