[1] Nonlocal thermodynamic equilibrium (non-LTE) simulations of the (CO)-C-12-O-16(1 -> 0) fundamental band, the (CO)-C-12-O-16(2 -> 1) hot band, and the isotopic (CO)-C-13-O-16(1 -> 0) band performed with the Generic Radiative Transfer and non-LTE population Algorithm (GRANADA) and the Karlsruhe Optimized and Precise Radiative Transfer Algorithm (KOPRA) have been compared to spectrally resolved 4.7 mu m radiances measured by the Michelson Interferometer for Passive Atmospheric Sounding (MIPAS). The performance of the non-LTE simulation has been assessed in terms of band radiance ratios in order to avoid a compensation of possible non-LTE model errors by retrieval errors in the CO abundances inferred from MIPAS data with the same non-LTE algorithms. The agreement with the measurements is within 5% for the fundamental band and within 10% for the hot band. Simulated (CO)-C-13-O-16 radiances agree with the measurements within the instrumental noise error. Solar reflectance at the surface or clouds has been identified as an important additional excitation mechanism for the CO( 2) state. The study represents a thorough validation of the non-LTE scheme used in the retrieval of CO abundances from MIPAS data. |
