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.
