What is radar clear air mode and why is it used?

Clear air mode is a radar setting used when there is little or no precipitation. It turns up the radar’s sensitivity so it can pick up very weak echoes from non-precipitation targets such as dust, pollen, insects, birds, smoke, or aerosols, and it’s tuned to reveal atmospheric motions in the absence of heavy rain. Because the radar is operating with higher sensitivity and often different timing parameters, it can extract wind fields and show atmospheric features like boundary-layer structure, turbulence, gravity waves, and shear zones. This mode is valuable for aviation weather and atmospheric research because it provides insight into wind patterns and other dynamic processes even when precipitation is scarce.
