N2 - Hydrochlorofluorocarbons (HCFCs) are the first, but temporary, substitution products for the strong ozonedepleting chlorofluorocarbons (CFCs). HCFC consumption and production are currently regulated under the Montreal Protocol on Substances that Deplete the Ozone Layer and their emissions have started to stabilize or even decrease. As HCFC-22 (CHClF2) is by far the most abundant HCFC in today's atmosphere, it is crucial to continue to monitor the evolution of its atmospheric concentration. In this study, we describe an improved HCFC-22 retrieval strategy from groundbased high-resolution Fourier transform infrared (FTIR) solar spectra recorded at the high-Altitude scientific station of Jungfraujoch, the Swiss Alps, 3580ma.m.s.l.
