Abstract
Project COLD CAN, supported by the Advanced Research Projects Agency, the United States Air Force and the Defence Research Board of Canada, was a program devised for synoptic study of the composition and latitudinal and seasonal variations of the upper atmosphere. The project ran for 3 1/2 years using the high-altitude RB-57F aircraft as an instrument platform. A summary of the organization, instrumentation and operations is presented along with a brief resume of the results obtained and data extracted. The Dry Stratosphere was confirmed, the concentration of water vapor lying between 1 and 2 mg/kg, with evidence of both latitudinal and seasonal variations. Carbon dioxide was found to be uniformly mixed over the altitude studied with an average concentration of about 300 parts per million by volume and an indication of decreasing concentration from north to south in the northern hemisphere.
