Some peculiarities of polarimetric classification for winter data takes

The paper demonstrates a difference in polarimetric classification results for winter and summer data takes. 30 PALSAR scenes over 2 Siberian test sites were processed, and the results were compared with meteoarchive data. Scattering matrix elements decrease in different way under freezing conditions, so the dominant scattering mechanism changes. Thus in winter the surface type of scattering becomes the prevailing mechanism even for forests, whereas in summer they demonstrate volume scattering.
