Hyper-spectral remote sensing may provide an effective solution to retrieve the methane (CH4) concentration in an atmospheric column. As a result of exploring the absorptive characteristics of CH4, an appropriate band is selected from the hyperspectral data for the detection of its column concentration with high precision. Following the most recent inversion theory and methods, the line-by-line radiative transfer model (LBLRTM) is employed to forward model the impact of four sensitive factors on inversion precision, including CH4 initial profile, temperature, overlapping gases, and surface albedo. The study results indicate that the four optimized factors could improve the inversion precision of atmospheric CH4 column concentration.
