Striping Removal in MOS-B Data

Abstract

MOS-B data corrected by standard calibration procedures are affected by "striping" in most channels. Striping arises because of the imperfect calibration of the detector characteristics. In this paper, we present a method for removing striping, in which the euqualization curves are estimated by explointing a data base of carefully selected homogeneous targets. We present the results obtained on sea target images. Such a case study is of great interest because it is related to ocean color applications, for which the MOS-B sensor was especially designed. We also estimate the reduction of striping noise in the equalized image by means of two appropriate indexes of quality.
