GOVERNMENT CONTRACT EXHIBIT

The radar station that Colorado State University is petitioning to license will be part of the
experimental radar network currently being deployed in the DFW Metroplex under FCC
license WD2XLI.

This experimental radar network is based on the new technologies and user research
conducted by the CASA (Collaborative Adaptive Sensing of the Atmosphere) project. CASA is
an NSF Engineering Research Center supported primarily by the Engineering Research
Centers Program of the National Science Foundation under NSF Cooperative Agreement
No. EEC­0313747. Colorado State University is a core member of the NSF’s CASA
Engineering Research Center.

CASA is dedicated to revolutionizing our ability to observe, understand, predict, and
respond to hazardous weather events. The center has pursued an innovative, densely
networked radar sensing paradigm to overcome the resolution and coverage limitations of
traditional weather radars. The low‐power, short‐range and close spacing of these radars
gives them the ability to scan low to the ground with very high spatial resolution.
Overlapping coverage allows each voxel in the network to be simultaneously viewed by two
or more radars, allowing for multi‐Doppler wind vector retrievals and a solution to the
increased attenuation experienced at X‐band. The CASA concept and related enabling
technologies developed by the CASA enterprise have been validated and evaluated in a
prototype system‐level test bed located in southwestern Oklahoma. The test bed has been
relocated to the DFW Metroplex with the following project goals:
1. To develop high‐resolution, two and three‐dimensional mapping of current and future
atmospheric conditions, focusing on the lower atmosphere, to detect and forecast severe
wind, tornado, hail, ice, and flash flood hazards.
2. To create impacts‐based, urban‐scale warnings and forecasts for a range of public and
private decision‐makers that result in measureable benefit for public safety and the
economy.
3. To demonstrate the value of collaborative, adaptive X‐band radar networks to existing
and future sensors, products, performance metrics, and decision‐making; and assess
optimal combinations of observing systems.
4. To develop models for federal/municipal/private partnerships that fund new
observation technologies and on‐going interdisciplinary weather system research.
