New Species Retrieved from MIPAS/Envisat

The Michelson Interferometer for Passive Atmospheric Sounding (MIPAS) is a limb-viewing infra-red fourier transform interferometer which operated on the Envisat satellite from July 2002 until April 2012.
MIPAS' detectors cover the spectral range 685-2410cm-1 (14.6-4.1μ),
containing the vibration-rotation bands of many trace gases, and the combination of limb-viewing geometry and high spectral resolution allows good discrimination of the signatures of many different species from the upper troposphere to the mesosphere.
The original list of ESA L2 products consisted of profiles of temperature, H2O, O3, HNO3, CH4, N2O and NO2. This was extended to include ClONO2, N2O5, CFC-11 and CFC-12 and subsequently CO, HCN, HCFC-22, CF4, CCl4 and COF2.
Here we present test results for potential new species to be included in the next reprocessing: C2H2, C2H6, OCS, PAN, SF6, SO2 and HDO.
