Four different rocket techniques provided data on ozone at Wallops Island, Virginia, during the Aladdin 74 program. The entire altitude region from 19 to 108 km was covered, the different techniques providing overlapping profiles that included the afternoon of June 29 and the early morning of June 30 (local time). There were systematic differences between the chemiluminescent sonde and UV absorption techniques, the sonde giving the greater densities. These differences became larger with increasing altitude up to the maximum common altitude, 62 km. Both airglow and absorption techniques indicate a density minimum at 81 km of 1–3 × 107 cm−3 and agree within the experimental errors in the overlap region down to 72 km. Above 90 km the airglow experiment shows a relatively constant but structured density profile. The mass spectrometer measured a considerably higher ozone density at 90 km with a rapidly decreasing scale height up to 108 km. The experimental results are compared with photochemical‐transport models.
