Résumé	Through most of the period from January 1969 to June 1971, a USAF RB-57F high altitude weather reconnaissance aircraft has carried special NRC instrumentation to measure and record stratospheric turbulence and horizontal temperature gradients encountered on routine flights at altitudes from 40,000 to 65,000 feet. The main purpose of this cooperative program, named "Coldscan", was to collect data on atmospheric conditions at altitudes to be flown by the supersonic transports. Eighty-eight missions were flown covering over 136,000 nautical miles, the major portion being over central and western United States, the Pacific Ocean south of Panama, and on proposed SST routes off the east coast of North America. This is the third Coldscan data report and includes a summary of the results of all 88 flights. Data are presented on the correlation between measured stratospheric turbulence and horizontal temperature gradients, on the altitude and geographical distributions of the turbulence and temperature change encounters, and on the positions of the recorded incidents relative to the jet stream. Part 2 of the report gives detailed accounts of a selection of 15 events from Flights 57 through 92 that showed significant temperature gradients or light to moderate turbulence. These presentations include time histories of the recorded variables, flight tracks showing event positions, and meteorological analyses.
