中文摘要：

大气辐射传输模型SCIATRAN是一种较新的高光谱分辨率大气辐射传输模型。结合欧洲空间局环境卫星（ENVISAT-1）搭载的SCIAMACHY传感器在Limb观测模式下的相关参数,利用SCIATRAN模型模拟传感器辐射亮度值,将模拟得到的辐射亮度值与SCIAMACHY传感器实测数据的辐射亮度值进行对比,通过对比发现模拟值辐射亮度曲线总体走向、趋势和分布上与实测值符合较好,但存在差别。通过对臭氧廓线数据、气溶胶以及地表反照率数值进行调整分别模拟,经分析得出SCIATRAN模型中自带臭氧廓线数据和真实的臭氧廓线数据存在差异是模拟和实测辐射亮度值存在差别的主要原因。

英文摘要：

Atmospheric radiative transmission model, SCIATRAN is later high-spectral resolution atmospheric radiative transmission model. Its main control file parameters and its geo-control file parameters to simulate the value of the radiation intensity of the SCIAMACHY on European Space Agency environment satellite ENVISAT-1 are simply introduced it, and up set. Comparisons between the simulated spectral curve and the spectral curve measured by SCIAMACHY are made, the reasons of existent difference are analyzed, and the problems that should pay attention to are sumed up in using this mode. By changing the parameters i.e. ozone profiles, aerosol and surface albedo lonely in each simulation, differences between the simulated and the surveyed are caused mainly by the difference between the ozone profile in the model and the real ozone profile.
