ABN 72 112 121 801
Upper-air wind profiler
Typical radar installation
KEY FEATURES
- Upper-air wind profiling system
- Sampling range from 1 km to 20 km AGL
- Real-time wind profiles
- Low operating costs
- Fully automated allows unattended operation
- Doppler Beam Swinging (DBS) operation
- Remote monitoring and control
- BUFR output for easy data assimilation
- Unaffected by precipitation, bird or insect migration
ATRAD wind profilers provide a highly cost-effective measuring solution with a very low total cost of ownership. Ongoing maintenance requirements are minimal, operation is unattended and there are no recurring consumable costs. Any number of radars may be remotely controlled from a central location. BUFR data output is provided to enable easy data assimilation into existing observation networks.
Example Windbarb display
The ATRAD Upper-Air Windprofiler uses Doppler Beam Swinging (DBS) techniques to provide real-time vertical profiles of horizontal wind speed and direction at heights of up to 15 - 20km above ground level. It operates in the low-VHF frequency range, providing significant cost benefits and eliminating data contamination arising from precipitation, birds or insects.
The Upper-Air Windprofiler provides a low-cost alternative to meteorological balloon stations for wind profiling applica- tions. Alternatively, it may be used in conjunction with a meteorological balloon station to reduce the number of costly balloon flights per day. It also has applications in rocket & space launch operations and scientific research.

OTHER NOTES
Maximum height coverage achieved by radar is determined by radar power, atmospheric conditions and is subject to seasonal and diurnal variation. Minimum height coverage is affected by local clutter conditions.
