Abstract
An IR solar spectrometer (ISS), which basically consists of three components: coelstat, spectrometer and data acquiring unit, was developed. With ISS we measured the solar spectra in the wavelength range of 2915 - 2920 cm-1 on the ground to derive the abundance of atmospheric CH4. In this spectrum range, CH4 is the main absorption gas and other gases' absorption can be omitted. The measurement results in the winter of 1991 show that the mixing ratio of CH4 is around 1.6 ppm, with the mean measurement error about 10%.
