SODAR

SODAR (Sonic Detection and Ranging) is a remote sensing tool that uses sound waves to measure atmospheric conditions. It emits sound pulses upward and analyzes the returning echoes caused by airflow and temperature variations in the atmosphere. This allows it to determine factors like wind speed, direction, and turbulence at different heights. SODAR is useful for studying weather, guiding wind energy projects, and monitoring atmospheric stability, providing real-time data without direct contact with the environment. It is a non-invasive, efficient way to understand the vertical structure of the atmosphere around us.
