Abstract

Due to correlations among high resolution infrared sounder radiances and retrieval computation efficiency, it is prudent to use a set of statistically less correlated channels which not only retains the majority of measurement information but also yields the most accurate atmospheric profile retrievals. The statistical procedure of these channels selection is described in the paper. The use of optimal selected channels simulated for the measurements of AIRS (Atmospheric InfRared Sounder) in the statistical / physical retrieval is discussed. Simulated AIRS inversion results demonstrate the advantages of using optimal channel set that produce the accurate and stable retrieval solution.
