Utilization of the first three Stokes parameters for the determination of precipitation characteristics

摘要

The magnitudes of the third Stokes parameter for up- and downwelling microwave emission and scattering by layers consisting of oriented nonspherical hydrometeors are estimated. In the case of downwelling radiation, incident Sun emission is also considered. It is shown that the third Stokes parameter has measurable values under certain conditions and can be utilized in addition to the first and the second Stokes vector components in order to derive microphysical parameters of the precipitation.
