Retrieval of Atmospheric CO2 and CH4 Variations Using Ground-Based High Resolution Fourier Transform Infrared Spectra
Figure 3
CH4 spectral fitting within 5938 cm−1 window: the spectrum was recorded on October 8, 2014, 0:47 (UTC). Black lines are the measurements, orange lines are the fitted transmittance, and contributions from individual gases are shown in color. Fitting residuals () for CH4 are 0.3535%.
