Measurements of stratospheric HF have been made by the JPL MkIV interferometer during high-altitude balloon flights. Infrared solar absorption spectra were acquired near 35{degrees}N at altitudes between local tropopause and 38 km. Volume mixing ratio profiles of HF derived from 4 flights (1990-93), in conjunction with simultaneously observed N{sub 2}O profiles, indicate an average rate of HF increase of (5.5{+-}0.3)% per year, in agreement with time-dependent, two-dimensional model simulations (6% per year) and ATMOS measurements. 17 refs., 3 figs., 3 tabs.
