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.
