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.enThe original publication is available at www.springerlink.comHydrochloric acidchlorine cyclemaritime troposphereTDLASboundary layerAn Upper Limit on the HCl Near-Surface Mixing Ratio at 28oN, 30oW Measured using TDLASArticlehttp://www.springerlink.com/content/100279/http://www.springerlink.com/content/t181558m06l12981/?p=2192e1e6820e4dabb18130a83f504630&pi=1
