Retrieval of CLAES Filter Shapes from Spectral Calibration Data

Abstract

The Cryogenic Limb Array Etalon Spectrometer (CLAES) will derive Stratospheric temperatures and constituent number densities from the measurement of infrared spectral emissions, during its 18 month mission on board the NASA Upper Atmosphere Research Satellite (UARS). Overviews of the CLAES experiment and hardware are given by Roche et al (1) and Burriesci et al. (2). This paper describes the mathematical inversion of system cold test calibration data described by James et al.(3) to retrieve system spectral blocker filter profiles in the pressure and temperature retrieval channel centered at 791.5 cm-1.
