Abstract : An airborne refractometer system was designed, fabricated, and installed in a C-131 type aircraft based at Patrick AFB, Florida along with a vortex thermometer, Rosemont total temperature probe, an aerograph sensing head, and a pitot-static pressure probe. A duplicate refractometer system was fabricated and delivered to the Cloud Physics Branch altitude chamber for use in calibrating the systems. A lightweight vortex thermometer was assembled and tested at the AFCRL Fog Field Site at Otis AFB. The AFCRL Fog Research Site at Otis AFB, Falmouth, Massachusetts, is fully described in this report for the 1964 Operation Cat Feet program during which most of the testing of instruments was performed. A comprehensive study of the factors involved with the measurement of gust velocities by various techniques is given in this report. Analysis of the acceleration data acquired by the Cloud Physics C-130 and the computed theoretical response of the aircraft show that this aircraft data can be used with a good degree of accuracy in determining the atmospheric gust velocities at lower frequencies of the gust spectrum.
