Clear Air and Precip modes
Each NEXRAD site can operate in two modes, "Clear Air" mode or "Precipitation" mode. A NEXRAD site produces "Clear Air" images when no significant precipitation exists in the scanning area of the radar. In this mode the radar is very sensitive to small targets, and it can detect even minute particles such as pollen, smoke and dust. In the following reflectivity image a NEXRAD site operating in "Clear Air" mode detects insect and bird targets.
