Comment on Modified Stokes Parameters

It is common practice in passive microwave remote sensing (microwave radiometry) to express observables as temperatures and in the case of polarimetric radiometry to use what are called ldquomodified Stokes parameters in brightness temperaturerdquo to describe the scene. However, definitions with slightly different normalization (with and without division by bandwidth) have appeared in the literature. The purpose of this paper is to present an analysis to clarify the meaning of terms in the definition and resolve the question of the proper normalization.
