  • Why Does the Non-Orthogonal Sonic Anemometer Underestimate

    The performance of non-orthogonal sonic anemometers has been the subject of much discussion in recent years.  It followed findings that they underestimated vertical winds and vertical heat fluxes by 10-15%.  For agricultural and forestry scientists who depended on them for their large-scale energy balance studies this was a bad surprise.  They had collected turbulence data from ...

  • Verification of wind energy related measurements with a SODAR system

    Abstract Complex terrain and growing wind energy converters (WEC) in wind parks generate increasing interest in determining wind profiles and turbulence besides the general forecast of annual energy production. Increasing hub heights and growing rotor diameters of advanced WEC make SODAR systems a valuable alternative to meteorological towers. SODAR systems provide wind profiles as well as ...

  • Effects of spatial filtering, prefiltering, and aliasing in measurements from applied technologies` Sonic K-Probe

    The Applied Technologies' Inc. (ATI) K-probe measures wind components along three mutually orthogonal axes separated spatially from each other to minimize flow distortion errors. The sonic anemometer samples the wind at a 100-Hz rate but constructs 0.1-s (10-point) non-overlapping block averages to provide. a 10-Hz data train for internal processing. This digital prefiltering is designed to ...

  • Amassing Wind Information

    Wind is a variable resource, but not an indecipherable one. Second Wind encourages harnessing the full range of wind sensing technologies that are available today. When it comes to wind information, much attention is focused on the choice of wind measurement technology and data collection practices in wind resource assessment and project design. Right now, wind data plays a limited role in the ...
