A prototype of the barnes infrared spectrometer proposed as a clear air turbulence detector has undergone initial flight tests while mounted on the Canadian National Aeronautical Establishment T-33 turbulence research aircraft. Advance warning of up to 8.5 nautical miles before interception of horizontal atmospheric temperature variations were recorded. A high correlation between temperature variations and mountain waves and/or turbulence was found during the tests. The necessity of pitch stabilizing such a device against spurious aircraft attitude changes has been demonstrated. (Author)
