Q. Consider the following statements:
1. SODAR (Sonic Detection and Ranging) is used to measure the wind speed.
2. One of the defects of SODAR is relatively hard to transport and assemble.
Which of the statements given above is/are correct?
As the wind energy industry expands and larger-scale projects are developed, wind turbines are becoming larger in rotor diameter as well as in hub height.
- Accordingly, it is becoming difficult to accurately assess the wind resource with standard cup anemometers mounted on standard height (60m) meteorological (met) towers.
- For this reason, attention is being directed to other methods of wind speed measurement, such as SODAR (Sonic Detection and Ranging).
- Since the SODAR can measure wind speed as a function of height and is relatively easy to transport and assemble, the technology is very appealing.
