Abstract

Two approaches have been explored for the retrieval of atmospheric constituent and aerosol extinction profiles from radiance measurements made by a limb sounding satellite radiometer. One of the retrieval schemes can be used with different signal to noise ratios and with measurements from different spectral regions. Multiple constituents can be retrieved simultaneously. Characterization and error analysis of the retrieved products arise naturally from theoretical considerations. The algorithms have been implemented on CLAES, an infrared limb sounder on the upper atmospheric research satellite. The CLAES measurement technique requires the level 1 extracted radiance data from CLAES to be processed before they are input to the NCAR research retrieval algorithm. The algorithms are applied to blocker 3 radiance measurements and some initial results are presented.
