Impact of difference in absorption line parameters in spectroscopic databases on CO2 and CH4 atmospheric content retrievals

摘要

The impact of uncertainties in CH4 and CO2 absorption line parameters in modern spectroscopic databases on the atmospheric transmission simulation in the near-infrared region is investigated. The atmospheric contents of CH4 and CO2 are retrieved from the absorption solar spectra measured by a ground-based Fourier transform spectrometer. Different spectroscopic databases are used in the forward radiative transfer model and a comparison of the retrieved results is made. (C) 2016 Elsevier Inc. All rights reserved.
