The vertical profile and total column concentration of HCl have been measured from ground based high resolution infrared absorption spectra. The lines recorded were the R 1 and P 5 of HCl 35 at 2942.731 cm −1 and 2775.760 cm −1 respectively. Vertical profiles and column concentrations are reported for different seasons. Measurements indicate an HCl volume mixing ratio equal to (2.2 ± 0.5) × 10 −11 at 10 km increasing to (3.4 ± 0.6) × 10 −9 at 33 km.
