The Best Air Turbulence Probe, also known as the BAT probe, was invented in the late 1980’s by NOAA in an effort to better measure wind turbulence. The bat-shaped probe is equipped with a number of pressure sensors and a temperature sensor. Perturbations measured by those probes are then translated into wind flow measurements. Although the bat probe has been used on a number of different aircraft, it is most commonly used on the Airborne Laboratory Atmospheric Research (ALAR), which is owned and operated by Purdue University.
