Abstract
Ground‐based infrared solar spectra at 0.02 cm−1 resolution obtained at the Amundsen‐Scott South Pole station in December 1986 have been analysed for the atmospheric content of HCl. Nonlinear least‐squares spectral fitting applied to the spectra yields a total HCl column amount of (6.4 ± 0.8) × 1015 molec/cm², most being stratospheric. This amount is larger than that extrapolated from earlier results on the latitudinal distribution of atmospheric HCl.Keywords
