Snow depth retrieval based on a novel sea ice concentration algorithm from AMSR-E datasets

Temporal tie points have been manually selected for sea ice concentration retrieval based on the linear combination relationship between the open water and the complete ice coverage pixel. In this paper, the multichannel information has been exploited using the constrained least-squares linear unmixing algorithm from AMSR-E multi-channels brightness temperature. Snow depth can be obtained from the innovative algorithm without considering the weather effect.
