2045536 9010203 PCTABS00002 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 µm 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.
