Magnetic dipole and electric quadrupole absorption in carbon dioxide
Montmessin, F.; Fedorova, A.; Korablev, O. I. +3 more
Magnetic dipole and electric quadrupole absorption in carbon dioxide are addressed in details. The selection rules for both processes are presented. The equations for the line intensities are given. In the case of the quadrupole absorption the Herman-Wallis functions are derived. The results of the present paper were used in the analysis of the ca…
Machine learning for automatic identification of new minor species
Erwin, Justin; Daerden, Frank; Ristic, Bojan +9 more
One of the main difficulties to analyze modern spectroscopic datasets is due to the large amount of data. For example, in atmospheric transmittance spectroscopy, the solar occultation channel (SO) of the NOMAD instrument onboard the ESA ExoMars2016 satellite called Trace Gas Orbiter (TGO) had produced ~ 10 millions of spectra in ~ 20000 acquisitio…
The RISOTTO radiative transfer and retrieval pipeline for the analysis of occultation spectra
Montmessin, F.; Ferron, S.; Braude, A. S.
We present a new radiative transfer and retrieval pipeline, referred to as RISOTTO, designed for observations made in occultation geometry. RISOTTO can retrieve accurate vertical profiles of the constituents of a planetary atmosphere using a Bayesian approach while simultaneously correcting for instrumental artefacts and uncertainties. The algorit…
