The samples were taken during routine training flights along the
flight tracks shown in Fig. 2. Normally four samples, with a sampling
time of 45 min for each, were taken during each flight, two above and
two below the tropopause. The outside air temperature was monitored
during each flight and utilized whenever possible as an indicator of the
tropopause height. In-flight wind speeds were recorded from the air-
craft’s radar bombing system, and a log of in-flight information was
taken.
Unfortunately, we were unable to collect sufficient CO, with this
sampler to determine the “C content; however, we found that the Ascarite did serve as a filter medium for nuclear debris.
