sonic anemometer

sonic anemometer

[′sän·ik ‚an·ə′mäm·əd·ər]
(engineering)
An anemometer which measures wind speed by means of the properties of wind-borne sound waves; it operates on the principle that the propagation velocity of a sound wave in a moving medium is equal to the velocity of sound with respect to the medium plus the velocity of the medium.

In addition, the velocity of the air generated by the sprayer was measured in the absence of any wind using a WindMaster 3D sonic anemometer (Gill Instruments, UK) according to the methodology developed by [11].
When detection is made, the algorithms process the GPS coordinate along with the wind speed and direction from the sonic anemometer to provide a methane-indication investigation area.

The high degree of agreement in 10-min-averaged wind speeds between collocated lidars and MM-mounted anemometers is in accord with a similar intercomparison conducted in Denmark that found that for a forced zero intercept the regression line for data from a sonic anemometer and a ZephIR had a slope of 0.99 (Sathe et al.
