Abstract
A study of the gas phase mixing ratio of hydrochloric acid was made during the 1988 Polarstern expedition using tunable diode laser absorption spectroscopy (TDLAS). The measurements were made 22 m above sea level at 28° N, 30° W. The signal-to-noise ratio was unity for <50 pptv HCl, but because of wall effects in the sampling system, only an upper limit for the HCl mixing ratio of <250 pptv can be stated.
