Concentrated samples of stratospheric air were obtained at pressure altitudes of 18.3 km and 21.3 km aboard U‐2 aircraft, and at 28.3 km and 35.9 km aboard a balloon platform. The mixing ratios of CF 2 Cℓ 2 and N 2 O are reported for locations in California, Oregon, Texas, and Quebec, Canada. The observed mixing ratios compare within a factor of 2 to those reported by other investigators and show a more rapid decrease with altitude than predicted by a two‐dimensional (2‐D) model.
