摘要

The fundamentals on non-local thermodynamic equilibrium (non-LTE) in the atmosphere are briefly described as well as for which atmospheric emissions, in which regions and for which instruments (viewing geometry, spectral coverage and resolution), non-LTE processes are more important. The retrieval of atmospheric species from non-LTE infrared emissions and the different options for performing non-LTE retrievals are discussed. The IMK/IAA non-LTE retrieval scheme for inverting atmospheric species from the MIPAS spectra and its application to the retrievals of the CO and NO abundances and non-LTE parameters related to the CO_2 levels emitting near 4.3 μm are described. Finally, a non-LTE parameterization of the CO_2 4.3 μm daytime outgoing radiation in the nadir view is described and its potential application to low altitude atmospheric temperature sounding from nadir infrared instruments is discussed.
