| Research Abstract |
In this study, novel techniques on application of microwave remote sensing data for monitoring permafrost ecosystem and for mapping snow-covered area have been developed. Previous studies on monitoring thaw and refreeze states of permafrost environment have a limited spatial scale of 25-50km. In this study, a new technique to detect freeze/thaw states of the Siberian ecosystem in the spatial resolution of 1km was originally developed. In addition, a new method to map seasonal snow-covered area from radar remote sensing image was developed based on the characteristic seasonal changes of polarimetric parameters and a new data fusion method. Experimental results applied to Niigata Prefecture, indicate that the fully polarimetric L-band data can be a useful tool for mapping seasonal snow-covered area.
