sodar [′sō‚där]
(engineering) Sound-wave transmitting and receiving equipment that is used to remotely measure the vertical turbulence structure and wind profile of the lower layer of the atmosphere by analyzing sound reflected in scattering by atmospheric turbulence. Derived from sonic detection and ranging. Want to thank TFD for its existence?

Additionally, similar to the ground clutter problem with SODAR systems for wind measurements, the reflection of the sound waves from the room interior surfaces and objects may overwhelm the return signal from the scattering particles and cause the measurement to be unreliable. Similarly, some projects are aimed directly at alternative sustainable energy production, such as the application of SODAR and other technologies to the mapping of winds and to wind turbine siting, with partners such as Gordon First Nation and Cowessess First Nation. |
