Abstract

In this paper we used VLIDORT procedures as a forward model in FIRE-ARMS code for modeling the spectra and Jacobian calculation in both thermal infrared (TIR) and short wavelength infrared spectral bands (SWIR). Simulated spectra are compared with spectra measured under clear sky conditions over Western Siberia by the Fourier spectrometer TANSO-FTS, on board of the GOSAT satellite. With the new software, operating simultaneously in both bands, Jacobians were calculated in order to retrieve vertical profiles of carbon dioxide and methane in TIR and SWIR. Data from NCEP/NCAR reanalysis were used as initial guess model atmosphere.
