摘要：
The total column-averaged volume mixing ratio of atmospheric carbon dioxide(XCO2)has been retrieved with high spectral resolution solar absorption data obtained from ground-based Fourier transform spectrometer(FTS)measurements at Xichong,a coastal site in the district of Shenzhen in southern China.Based on differential optical absorption spectroscopy(DOAS)theory,the XCO2was retrieved by finding the best match of observed high spectral resolution solar absorption data and monochromatic radiation transfer model calculations.The averaged XCO2in the whole observation period was about 394.9 ppm.The uncertainty of the retrieval was estimated to be 2.0 ppm(0.51%)by comparing retrievals at two bands.The preliminary results show that XCO2retrieved by this method can be used to validate satellite remote sensing of XCO2:
