Abstract

The retrieval ofthe non-LTE ro-vibrational populations ofthe CO2 molecules and line source functions has been performed from numerically simulated high resolution limb spectra in the 15 m and 4.3 p.m spectral region, which imitate the limb radiance measurements to be obtained by the MIPAS (Michelson Interferometer for Passive Atmospheric Sounding) experiment on board the European Space Agency's ENVISAT- 1. The possibility of retrieving kinetic and vibrational temperatures in the middle and upper atmosphere from the values of populations and source functions is studied.
