Short summary

The photolysis of CFCs, and to a lesser extent of HCFCs, in the stratosphere leads to the appearance of so-called ozone holes. We improve the retrieval strategies for deriving CFC-11, CFC-12, and HCFC-22 from ground–based IR solar radiation spectra measured by a Bruker FS125HR spectrometer, analyze the time series at the Network for the Detection of Atmospheric Composition Change (NDACC) site in St. Petersburg, Russia, and compare them to the independent data.
