Abstract
Altitude profiles of the stratospheric trace gases HCl and HF were simultaneously measured for the first time on 13 February 1992 at ESRANGE (68°N, 20°E, Northen Sweden) with a balloon‐borne CIMS (Chemical Ionization Mass Spectrometry) ‐instrument. The measured maximum volume mixing ratios (VMR's) for HCl and HF are 2 ppbv and 0.6 ppbv, respectively, at 25 km. A comparison of the observed HCl VMR's with data from midlatitudes and model predictions shows, that the present VMR's of HCl are similar to VMR's of out‐of‐vortex situations.This publication has 8 references indexed in Scilit:
