Williamson. these flights, at a float altitude of 28km, carried instruments to measure ozone overburden, ozone density, water vapor, x-ray radiation, CO2 and methane. The balloons remained aloft for periods of 31, 83, and 121 days making several circumnavigations of the globe at latitudes varying from 14 degrees south to 70 degrees south carrying a 28kg payload.
