The simultaneous measurement of the 1--0 bands of HCl and HF has been achieved from near-infrared solar absorption spectra obtained during a balloon flight near Fairbanks, Alaska (65 ¿N, 148 ¿W) in the evening of May 22, 1976. Several lines from each band have been measured to provide volume mixing ratio profiles for both constituents from 15 to 30 km. The HCl profile is consistent with the results of other workers, however the HF profile shows a substantially larger concentration than a recent determination.
