Abstract: An improved clear air turbulence (CAT) detector (100) sensing infrared radiation in the 27-33 micrometer range of the water vapor rotational wavelength band. The improved clear air turbulence detector (100) for use on an aircraft includes a forward looking and upwardly oriented between 8 to 12 optical assembly (300) having a thallium bromoiodide infrared lens (410), a 27-33 micrometer wavelength interference filter (420) and an infrared detector (430); a radiometer amplifier (320) for amplifying the output of the optical assembly (300) and for generating an analog voltage signal (330) related to the received infrared intensity, a processing unit (340) for analyzing the analog signal, and a display unit (360) for generating a first signal (370) when no clear air turbulence is detected, a second signal (380) when a moderate turbulence is detected, and a third signal (390) when extreme turbulence is detected. A method for determining the advance time for entering the clear air turbulence after detection is based upon the altitude of the aircraft.

Abstract: Air turbulence (windshear as well as clear air turbulence) in navigable airspace is detected by remotely sensing changes in the spatial temperature profile of an air column ahead of an aircraft by repeatedly sensing the intensity of the thermal radiation from the column of atmospheric air in at least two spectral peaks in the 4.17 to 4.2 νm region of the CO2 spectral emission band, and comparing the relative intensity of the spectral peaks over time. Apparatus which includes a tunable Fabry-Perot etalon is provided for the practice of the method.
