WindTracer(R) Deployed at McCarran Airport for FAA Evaluation FAA to Conduct Analysis of Lidar Data



    BOULDER, Colo., Sept. 8 /PRNewswire/ -- CLR Photonics, Inc. -- a world
 leader in the development of lidar-based remote-sensing solutions designed for
 airport and meteorological applications -- today announced that its
 WindTracer(R) pulsed Doppler lidar system has been deployed at McCarran
 International Airport in Las Vegas in a joint program with the Federal
 Aviation Administration.  This deployment enables the demonstration and
 evaluation of WindTracer by the FAA as a wind shear detection solution and
 cost-effective complement to the Terminal Doppler Weather Radar (TDWR) system
 currently in operation at McCarran Airport.
     "We are pleased that the FAA is evaluating WindTracer as a viable wind
 shear detection system," said Dr. Stephen M. Hannon, CLR's managing director.
 "We are anxious to work with the FAA to analyze the data that confirms the
 quality of lidar technology and emphasizes WindTracer's contribution to
 aviation safety."
     CLR has provided one WindTracer system for the multi-month evaluation,
 facilitated through the FAA's Air Traffic Organization Technical Operations.
 The WindTracer is situated on McCarran Airport property with a clear view of
 the runways.
     At airports located in Western states, like McCarran Airport, the existing
 microwave TDWR can fail to detect significant dry microbursts as well as
 frontal passage events in the airport terminal area.  Due to its geographic
 location and desert climate, McCarran Airport is also prone to dramatic wind
 events, such as strong downburst winds that result from the seasonal
 "monsoonal flow," typically occurring during the late summer months.  Aircraft
 are forced to execute unexpected "go arounds" after encountering these sudden
 wind hazards.
     Air traffic control personnel are interested in an improved alerting
 capability at McCarran Airport.  A current approach is to augment the existing
 TDWR by installing an extensive network of Low Level Windshear Alert System
 (LLWAS) anemometer towers, which can be quite expensive and will generally
 encounter a variety of environmental impact concerns.  An alternate approach
 would be to augment the TDWR with WindTracer, a single-sensor installation
 that provides high-resolution glide slope coverage with little to no
 environmental impact.  During this summer's demonstration and evaluation, data
 collected by WindTracer will be compared with the TDWR data to identify the
 improvement provided for terminal-area wind hazard alerting.  Since the
 WindTracer installation in late July, several events have been recorded that
 demonstrate lidar's contribution to aviation safety and runway management.

     CLR Photonics, Inc. (www.clrphotonics.com) is a division of Coherent
 Technologies, Inc., a global leader in laser radar technologies since 1984.
 Headquartered near Boulder, Colo., CLR offers the only commercially available
 Doppler lidar system in the world today.  WindTracer is a pulsed Doppler lidar
 device that uses an infrared, eye-safe laser to bounce off aerosols less than
 the width of a human hair, providing wind and aerosol data for detecting
 airport wind hazards and wake vortices, as well as for homeland security and
 meteorological research.
