Upper-air wind profiler


Example Windbarb display		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.

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.
