    Abstract
  • In order to precisely retrieve the atmospheric CO 2, a retrieval method based on both near infrared (NIR) and thermal infrared (TIR) is established firstly. Then a look-up-table (LUT) based fast line-by-line radiative transfer model (RTM) was integrated into the retrieval procedure to accelerate radiative transfer calculations. The LUT stores gas absorption cross-sections as a function of temperature, pressure and wavenumber. It could greatly reduce calculating time in radiative transfer compared to direct line-by-line method. Then retrieval was simulated using NIR, TIR and both bands. The retrieved CO 2profiles suggest joint approach could reconstruct CO 2profile better than those using NIR or TIR alone. Joint retrieval using both bands simultaneously could provide better constrain to CO 2vertical distribution in the whole troposphere.
