Interpretive Summary:

Technical Abstract: The effect of ice on the polarimetric 4th Stokes component observations is investigated using WindSat data over Antarctica. The difference in the magnitude of the signal observed during (July 2003) and summer (February 2004) months is investigated using a second harmonic sine function of the azimuth look angle. The seasonal variations are further investigated by a time series of the 4th Stokes component for a location in Wilkes Land in east Antarctica and compared with a time series observed by the ERS scatterometer (EScat) from a previous work. The paper discusses the potential of a polarimetric radiometer in providing information about scattering and thermal properties of a snow ice pack.
