ClO infrared emission spectrum retrieval using the Michelson Interferometer for Passive Atmospheric Sounding (MIPAS)
Infrared emission spectra for atmospheric profiles consisting of 17 gases, including chlorine monox-ide (ClO) corresponding to maximum observed lev-els (Antarctic winter), were simulated using the Ref-erence Forward Model (RFM) developed at the Uni-versity of Oxford for the forthcoming European Spac...
