A Doppler-SODAR (SOnic Detection And Ranging) system is a ground based remote sensing system for the measurement of vertical profiles of the horizontal wind vector and turbulence in the lower parts of the atmosphere.

It is an acoustic wind and turbulence profiler which is mobile and gives a continuous near real-time three-dimensional vertical profile of the overhead wind structure. Temperature profiles can also be included using the optional RASS extension.

SODARs do not require any planning permission, structural masts or permanent fixings and can be transported conveniently in a standard van which simplifies the installation at remote sites. The system installation will take one trained operator less than one hour.

They are an excellent tool for many applications, in particular:

  • atmospheric research a SODAR allows the user a better understanding of the boundary layer and any local effects of wind on meteorology.
  • airport site evaluation (including wing tip vortex studies, low level wind shear or other turbulent structure monitoring along the glide path or elsewhere on the airfield).
      
  • plume modeling, flow dispersion, inversion levels or pollution monitoring are easily done with the graphic interface and imaging of the data from the SODAR.
      
  • ballistic meteorology such as artillery  This is far more cost effective than traditional radio-sonde flight releases during events and also allows a degree of independence as no consumables are required for continued operation.
      
  • wind farm siting research (they can show the all important effects that turbulence structures will have on the blades of  turbines, as well as aiding in establishing the power curve output for different sites). SODARs can be calibrated for wind energy applications and have been accepted by accredited organisations such as RISO.

Our SODARs are delivered as turn-key solutions, complete with SODAR antenna, SODAR control unit (PC-unit), software for the SODAR control and comprehensive Graphic Routine "METEK grafik.exe" for data visualization and analysis. No additional purchase of hardware or software is necessary to get the comprehensive SODAR data set. The toolkit even includes gloves and any small tools that might become necessary.

For use at remote sites there is a low power version for DC powered operation. This version can be supplied with weatherproof housing for the PC so that the whole SODAR system can be operated outdoors if required.

An optional GSM modem can be used to remotely log in and check or change settings and operation as well as allowing an SMS message to be sent when any potential problem should arise such as power fallout.
