摘要

摘要: 地基傅里叶变换红外光谱技术（Fourier transform infrared spectroscopy，FTIR）由于其具有高的时空分辨率、对地表大气浓度变化敏感等优点，已成为遥测温室气体柱浓度的重要技术。基于便携式的傅里叶变换红外光谱仪（EM27/SUN）采集的太阳光谱来反演北京市区CO₂与CH₄柱浓度。通过与高分辨率FTIR观测结果比对，验证了EM27/SUN观测的准确性和可靠性。同时利用正午观测的CO₂和CH₄柱浓度结果计算了CO₂与CH₄观测精度。其中CO₂的观测精度为0.16×10^-6，CH₄的观测精度为1.4×10^-9。最后，给出了CO₂与CH₄时间序列变化，CO₂与CH₄在观测期间的变化较为一致。该研究表明了便携式FTIR观测CO₂与CH₄柱浓度结果的准确性和可靠性。

Abstract: Ground-based Fourier transform infrared spectroscopy (FTIR) has become an important technology for monitoring greenhouse gas column concentration, due to its high spatiotemporal resolution and sensitivity to changes in surface atmospheric concentrations. This paper was based on the solar spectrum observed by a portable Fourier transform infrared spectrometer (EM27/SUN) to retrieve the CO₂ and CH₄ total column concentrations in Beijing. By comparing with high-resolution FTIR observation, the accuracy and reliability of EM27/SUN observation were verified. At the same time, the observation accuracy was calculated by using the concentration results of CO₂ and CH₄ column observations at noon. The accuracy of CO₂ was 0.16×10^-6, and the accuracy of CH₄ was 1.4×10^-9. Finally, the time series changes of CO₂ and CH₄ were presented, and the variation of CO₂ and CH₄ were more consistent during the observation period. This study shows that portable FTIR can accurately determine CO₂ and CH₄ column concentration.
