Sodar, or in full sonic detection and ranging, is a meteorological instrument used as a wind profiler to measure the scattering of sound waves by atmospheric turbulence.
What does Sodar stand for?
sound detection and ranging
What is sodar and LiDAR?
The difference between LiDAR and SoDAR is the type of wave used for measuring: LiDAR uses light which is reflected by aerosol particles in the air, SoDAR uses sound which is reflected by density variations in the air.
When was Sodar invented?
Sodar, which stands for sound detection and ranging, was first described as a research tool for probing the lower atmosphere by Little (1969) and McAllister et al. (1969).
What is sodar system?
Sodar, or in full sonic detection and ranging, is a meteorological instrument used as a wind profiler to measure the scattering of sound waves by atmospheric turbulence. Sodar systems are in fact nothing more than sonar systems used in the air rather than in water.
What does sodar measure?
A SODAR is a ground-based remote sensing instrument that transmits (via speakers) a short acoustic sinusoidal pulse (typically 50 ms) into the ABL, then listens for return signals for a short period of time, measuring the sound waves that are scattered back by turbulence caused by the thermodynamic structure of the
