Abstract. Water vapor is an important greenhouse gas. The atmospheric water vapor content is monitored by remote methods, which require accurate spectroscopic information about H2O absorption line parameters. The problems of accuracy of accounting the selective water vapor absorption in the simulation of atmospheric transfer of solar radiation are considered in this work. The atmospheric spectra are simulated using different versions of spectroscopic databases of H2O absorption line parameters and compared with the solar spectra measured by a ground-based Fourier transform spectrometer. The total column (TC) water vapor is retrieved from the solar spectra measured. The effect of the differences in absorption line parameters in modern spectroscopic databases on the results of retrieval of the TC water vapor from high-resolution spectra is estimated.

光谱信息对近红外光谱区总柱水汽反演的影响

摘要。水蒸气是一种重要的温室气体。大气水蒸气含量是通过远程方法监测的，这需要有关 H2O 吸收线参数的准确光谱信息。本工作考虑了在模拟太阳辐射的大气转移中对选择性水汽吸收进行计算的准确性问题。大气光谱使用不同版本的 H2O 吸收线参数光谱数据库进行模拟，并与由地面傅立叶变换光谱仪测量的太阳光谱进行比较。从测量的太阳光谱中检索总柱 (TC) 水蒸气。估计现代光谱数据库中吸收线参数的差异对从高分辨率光谱中提取 TC 水蒸气的结果的影响。
