Jaramillo, J., de Zafra, R.L., Barrett, J., Emmons, L.K., Solomon, P.M. and Parrish, A. (1989). Measurements of stratospheric hydrogen cyanide at McMurdo Station, Antarctica: Further evidence of winter stratospheric subsidence?. Journal of Geophysical Research 94: doi: 10.1029/89JD00931. issn: 0148-0227.

We have made measurements of hydrogen cyanide (HCN) in the springtime Antarctic stratosphere using ground-based millimeter wave spectroscopy. We find a steeper decrease in volume mixing ratio with altitude than that found at tropical latitudes, from an assumed value of ~160 pptv in the troposphere to a value of 65¿30 pptv at 40 km, which may be further evidence of substantial vertical subsidence of the Antarctic winter stratosphere. ¿ American Geophysical Union 1989
