抽象的。在实验室典型大气条件下，测量了全球臭氧监测实验2(GOME-2)飞行模型(FM)的臭氧吸收截面光谱，温度为203~293K，波长范围230~790 nm，中等光谱分辨率0.24~0.54 nm。由于所使用的气体流动系统中臭氧的确切数量是未知的，因此需要使用已发表的文献数据将测量的臭氧横截面定标为绝对横截面单位。同时记录了Hartley带、Huggins带和Chappuis带，它们的温度依赖关系与前人的研究(Hartley带和Chappuis带的温度效应较弱)符合得很好。GOME-2 FM截面与文献数据的总体一致性在3%以内。使用新的截面数据从GOME-2/MetOp-A卫星反演的臭氧总量与从对GOME-2执行的标准反演得到的臭氧总量相比在1%以内。
Abstract. The Global Ozone Monitoring Experiment-2 (GOME-2) Flight Model (FM) absorption cross section spectra of ozone were measured under representative atmospheric conditions in the laboratory setup at temperatures between 203 K and 293 K in the wavelength range of 230–790 nm at a medium spectral resolution of 0.24 to 0.54 nm. Since the exact ozone amounts were unknown in the gas flow system used, the measured ozone cross sections were required to be scaled to absolute cross section units using published literature data. The Hartley, Huggins and Chappuis bands were recorded simultaneously and their temperature dependence is in good agreement with previous studies (strong temperature effect in the Huggins band and weak in the Hartley and Chappuis bands). The overall agreement of the GOME-2 FM cross sections with the literature data is well within 3%. The total ozone column retrieved from the GOME-2/MetOp-A satellite using the new cross section data is within 1% compared to the ozone amounts retrieved from the standard retrieval performed for GOME-2.
