Abstract

Instruments with very high spectral resolution are needed to sound stratospheric temperatures from satellite. Maximizing the contributions of the stratosphere to the upwelling radiance measured by a particular channel can be achieved by using high spectral resolution channels positioned at strong carbon dioxide (CO₂) line centers. In this paper, the techniques of stratospheric temperature sounding from satellite are briefly reviewed. The feasibility of high resolution stratospheric temperature sounding with the multi-order etalon sounder (MOES), a high resolution Fabry-Perot array spectrometer, is discussed. Our simulation studies indicate that stratospheric temperatures can be derived with a root-mean-square (RMS) error of about 2 - 3 K with MOES. A scenario to add MOES to the next generation high resolution infrared sounder (HIRS/3) currently under development with minimal cost is suggested. With its compact size and ruggedness, MOES is an ideal candidate as the stratospheric temperature sounding unit for small environmental satellite platforms.
