This paper describes new measurements and modelling of the absorption of methane gas between 0.6 to 1.1µm, one of the most important gases observed in the atmospheres of the outer planets and Titan.
A series of methane spectra were measured at the UK's Natural Environment Research Council (NERC) Molecular Spectroscopy Facility (based at the Rutherford Appleton Laboratory, Oxfordshire, UK) using a Brüker 125HR Fourier Transform spectrometer. To approximate the conditions found in outer planet atmospheres, the spectra were measured over a wide range of pressures (5bar to 38 mbar) and temperatures (290-150K) with a path length of 14.4m. The spectra were recorded at a moderate resolution of 0.12cm-1, comparable with the expected Doppler line width at these wavelengths.
The measured spectra were then compared with calculated spectra using existing data. Finally, the new data set was used to derive transmittance functions by fitting a variety of physically based band models, which were then used to generate k coefficients to allow use in scattering radiative transfer calculations.
This work was supported by the UK Particle Physics and Astronomy Research Council and the UK Natural Environment Research Council.
