Abstract
Traditionally the temperature dependent characteristics of the CO2 band structures have been used by infrared atmospheric sounders to derive the temperature profiles of the troposphere and stratosphere. Since individual pressure/Doppler broadened CO2 line structures are also temperature dependent, it is possible to derive the temperature profiles of the atmosphere by resolving single CO2 spectral lines with high spectral resolution infrared sounder. In this paper, we first compare the techniques of deriving atmospheric temperature profiles from the CO2 band structures and the pressure/Doppler broadened spectral line structures. Then, we discuss a new IR sounder concept based on the high resolution Fabry-Perot interferometer, which derives the temperature profiles of the atmosphere by resolving individual CO2 spectral lines. Retrieval simulations using two different techniques are conducted to evaluate its performance relative to other IR sounders.
