Midday stratospheric OH density measurements have been carried out within the altitude interval of 31 to 24 km using the laser induced fluorescence technique deployed on a balloon‐borne gondola launched from Palestine, Texas on July 15, 1987. Laser output at 282 nm is produced with a pulsed, 17 kHz repetition rate, copper vapor laser pumped tunable dye laser. The OH mixing ratio ranged from 16±5 ppt at 31 km to 4±3 ppt in the 27 to 24 km region. Simultaneous ozone and water vapor measurements were also obtained with separate instruments.
