An upper limit on the HCl near-surface mixing ratio over the Atlantic measured using TDLAS

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 degree N, 30 degree W. The signal-to-noise ratio was unity for < 50 pptv HCl,...

Zusammenfassung: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 degree N, 30 degree 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.
