Paper Abstract

Considerable flight experience has established that CAT is frequently associated with temperature anomalies in the atmosphere. It is possible, in principle, to sense such anomalies remotely by the infrared radiation emitted by the atmosphere. This paper reviews the results of several years of flight tests conducted cooperatively by Barnes Engineering Company, and three major airlines (PAA, EA and TWA) to evaluate this technique. Initially, the instrumentation was designed to predict the horizontal temperature profile ahead of the aircraft along its flight path. While some success was obtained, much too high a false alarm rate was experienced. A vertical scan mode was then added to provide information on the vertical temperature structure. Flight results made with the vertical scan show that the radiometric signal responds to the vertical temperature structure of the atmosphere in accordance with theoretical expectations. By this additional dimension of temperature information, it is hoped that false alarm situations can be more effectively identified and eliminated.
