Linearization pseudo-noise and its effect on the retrieval of atmospheric state from infrared spectral radiances
Remote sounding of earth's atmosphere from upwelling infrared radiances is highly non-linear. A linearization step is typically involved in seeking for suitable solutions. This letter discusses possible problems which arise when combining the linearization step with schemes aimed at solving the inverse problem. Possible strategies which could be able to get rid of such problems are discussed, too. Copyright 1996 by the American Geophysical Union.
