Abstract

The results of limb radiance calculations in the 9.6 μm ozone absorption band are presented for the tangent heights 30 - 110 km. Deviations from local thermodynamic equilibrium (LTE) are taken into account for 20 vibrational transitions forming ν1 and ν3 bands. The monochromatic limb radiance in line contours has been investigated for fundamental and hot bands for LTE and non-LTE. Variations of radiance stipulated by variations of kinetic, vibrational temperatures and ozone concentration have been analyzed. For day- and night-time limb radiance spectra have been calculated for different spectral resolutions. The approach is suggested to retrieve ozone profiles under non-LTE conditions using high-resolution limb spectral measurements (e.g., obtained by space-borne devices of MIPAS type).
