Synthesized spectrum of gas mixture using HITRAN database

The dataset is the absorbance spectrum of a set of mixed gas (C2H6 , CH4 , CO, H2O, HBr, HCl, HF, N2O, and NO). The displayed image shows (C2H6 = 4.86  µm), (CO = 4.00  µm), (CH4 = 3.60 µm), (H2O = 8.06 µm), (HBr = 7.78  µm), (HCl = 8.36 µm), (HF = 6.28 µm), (N2O = 6.64 µm), (NO = 7.48 µm) when the SNR is 30 dB.The gas spectrum were sampled by 1, 000 pixels equally spaced between 1 µm and 7 µm wavelengths.The gas concentrations were randomly generated from a uniformly distributed between 0 − 10 µM.
