High resolution methane spectrometry for the atmosphere of the Earth
Methane (CH4) is the most abundant anthropogenic greenhouse gas after CO2 in the atmosphere of the Earth. To properly
assess its impact on the climate and to measure its concentration in the atmosphere using remote sensing techniques,
detailed knowledge of the infrared absorption spectrum of methane is crucial. This spectrum is complex. Despite
numerous laboratory studies devoted to them, the spectroscopic parameters characterizing the effects of pressure on the
profile of methane lines can still be improved. Our project aims to contribute to the improvement of this important information.
It focuses on the measurement of air broadening, shift and line mixing coefficients for methane lines observed in the
infrared range, starting with the pentad region between 2500 and 3300 cm-1, using Fourier transform spectroscopy and multi-spectrum
fitting techniques. The temperature dependence of these parameters will also be measured.
