Retrievals of the atmospheric methane content with use of new spectroscopic absorption line parameters

摘要

The atmospheric solar spectra are simulated using new data on methane absorption lines. A comparison of the simulatedspectra with the atmospheric spectra, measured by a ground-based Fourier spectrometer in the methane absorption bandsin the near-infrared spectral region, is carried out. The atmospheric column-averaged volume mixing ratio of methane isretrieved from the measured spectra.
