High-resolution solar absorption spectra were continuously collected by a ground-based Fourier transform infrared (FTIR) spectrometer to retrieve the total column of carbon monoxide (CO), hydrogen cyanide (HCN), ethane (C 2 H 6 ), acetylene and formaldehyde (H CO). The time series variation characteristics these gases analyzed. biomass combustion process is identified using correlations between monthly mean deviations HCN, C , CO versus satellite fire point data. months with high correlation coefficients (R > 0.8) peaks number are considered be occurrence. emissions in Anhui estimated enhancement ratios when was main driving factor gas concentration change. study proved ability FTIR system inferring period during estimating trace concerning combustion.
