Atmospheric Sounding

The Michelson Interferometer for Passive Atmospheric Sounding (MIPAS) instrument which operated on the Envisat satellite from 2002-2012 is a Fourier transform spectrometer for the measurement of high-resolution gaseous emission spectra at the Earth's limb. It operates in the near- to mid-infrared, where many of the main atmospheric trace gases have important emission features. The initial operational products were profiles of Temperature, H2O, O3, CH4, N2O, HNO3, and NO2, and this list was recently extended to include N2O5, ClONO2, CFC-11 and CFC-12. Here we present preliminary results of retrievals of the third set of species under consideration for inclusion in the operational processor: HCN, CF4, HCFC-22, COF2 and CCl4.

Absorption Features

We report the results of our observations of liquid parahydrogen in the mid-infrared and of liquid parahydrogen and orthodeuterium in their first and second overtone regions using a Bruker IFS 120 HR Fourier transform spectrometer. We have determined intensity parameters for individual absorption features where possible and indicate analogies between the spectrum of the liquid and the corresponding spectrum of the solid phase of the hydrogens.
