Radar Wind Profiler

Definition

A radar wind profiler is an advanced remote sensing instrument that uses radar technology to measure the vertical profile of wind speed and direction in the atmosphere. This system provides crucial data about atmospheric conditions by emitting microwave signals that reflect off atmospheric structures, enabling meteorologists to monitor wind patterns at various altitudes. This real-time information is essential for weather forecasting, research, and understanding atmospheric dynamics.
