SODAR (SOnic Detection And Ranging) is a tool used in the wind energy industry to measure wind speeds and directions at different heights. Think of it like a special weather radar that uses sound waves instead of radio waves. Wind energy companies use SODAR to figure out the best locations for wind turbines and to monitor wind conditions. It's similar to other wind measurement tools like LIDAR or met masts, but SODAR is particularly valuable because it's portable and can be moved from site to site easily. When you see this term on a resume, it usually means the person has experience with wind resource assessment or wind farm planning.
