The Retrieval of Vertical Profiles of Chlorine Source Gases and N2O5 from MIPAS-B-92 Limb Emission Spectra

Abstract

During the European Arctic Stratospheric Ozone Experiment (EASOE) the balloon-borne cryogenic Fourier transform spectrometer MIPAS (Michelson Interferometer for Passive Atmospheric Sounding) recorded several sequences of mid infrared limb emission spectra, which were used for the retrieval of vertical profiles of CFC-11, CFC-12, HCFC-22, CF4, and N2O5. These gases are characterized by very dense emission bands of unresolved lines. Results are consistent with the current theories of stratospheric dynamics and chemistry.
