Abstract：Recently, the greenhouse effect is well known and is of great worldwide concern. CO2 and CH4 are two of the main human activity-induced greenhouse gases in the atmosphere. It is important for environmental scientists to monitor their long-term variation. A Fourier transform infrared spectrometer was used to monitor the concentrations of CO2 and CH4 at a specific site in Beijing. The pollution air was passed through a long open path and the absorption spectra were collected over a period of a month. Quantitative analysis was performed by means of the nonlinear least square method using synthetically generated spectra, which was than convolved with instrumental line shape function. Ambient levels of CO2 and CH4 are reported with a time resolution of five minutes for 4-10, September 2005, and some analysis is present.
